International School of the Sacred Heart

A Mission Rooted in 116 Years of Tradition

The International School of the Sacred Heart (ISSH) was founded in 1908 by Religious of the Society of the Sacred Heart — the same global network of Catholic educators that operates over 150 schools worldwide. At its core, ISSH is guided by five Sacred Heart Goals: a personal faith in God, a deep respect for intellectual values, a social awareness which impels to action, the building of community as a Christian value, and personal growth in an atmosphere of wise freedom.

This framework is not merely decorative. It permeates how teachers design lessons, how students are assessed, and how the school community resolves conflict. Students are encouraged not only to achieve academically but to reflect on the purpose of that achievement — to become women who make a positive difference in the world.

From Mission Statement to Daily Practice

The official mission reads: "Rooted in the goals of the Society of the Sacred Heart, we educate young women of the international community in Tokyo to believe, learn, serve, connect and grow." Each verb in this statement corresponds to a pillar of school life: service learning programs, inter-cultural connection events, spiritual retreats, and academic rigor.

Teachers at ISSH are expected to integrate values education into every subject area. A science class might close with a discussion of ethical responsibilities in research; a literature class might connect a text's themes to questions of social justice. This approach distinguishes ISSH from purely academically-oriented international schools.

Holistic Assessment and Whole-Person Development

Assessment at ISSH deliberately spans multiple modalities — written examinations, projects, oral presentations, group discussions, and end-of-year comprehensive finals in Grades 8–12. This design reflects the belief that no single test can capture the full dimensions of a young person's growth. Students are evaluated not only on content mastery but on how well they articulate ideas, collaborate with peers, and demonstrate intellectual curiosity.

Implications for Families

For families considering ISSH, the philosophy means that the school is a strong fit for those who value character development alongside academic excellence. Students who thrive here tend to be reflective, socially engaged, and open to spiritual and ethical inquiry — regardless of their own religious background. The school welcomes students of all faiths, though the Catholic ethos is clearly present in the chapel, the liturgical calendar, and the service culture.

Origins in Meiji Japan

In 1908, four French Religious of the Society of the Sacred Heart crossed the Pacific to Yokohama during the Meiji era of rapid modernization. Their mission was to establish a school offering a Catholic, bilingual education to girls in Japan's growing international community. The school they founded would become the International School of the Sacred Heart.

The timing was significant. Meiji Japan was actively engaging with Western culture and education, and elite families — both Japanese and foreign — were seeking institutions that combined intellectual rigor with moral formation. The Sacred Heart network, with schools already operating in Europe and the Americas, was well-positioned to fill this niche.

Relocation and Resilience

The 1923 Great Kanto Earthquake devastated much of Yokohama and Tokyo. Like many institutions, the school was forced to relocate. It reestablished itself in Hiroo, in the Shibuya ward of Tokyo — a leafy, residential neighborhood that would become home to many foreign embassies and expatriate families. This location remains the school's home today.

Through World War II and the postwar reconstruction, ISSH maintained its identity as an English-medium institution with deep ties to the international community. It was among the first schools in Japan to gain recognition from Western accreditation bodies: WASC accreditation was achieved in 1979, and CIS accreditation followed in 1997.

Growth into the 21st Century

Today ISSH enrolls approximately 585 students from around 50 nationalities, spanning Kindergarten 3 through Grade 12. The school is a founding member of the Japan Council of International Schools (JCIS), a member of EARCOS, and affiliated with the Kanto Plain Association of Secondary Schools (KPASS) for interscholastic athletics and arts competitions.

The school has grown its academic program over the decades, adding 23 Advanced Placement (AP) courses at the high school level and building out robust programs in music, drama, visual arts, and STEM. Yet despite this growth, ISSH retains the intimate atmosphere and values-centered culture that have defined it for over a century.

A Deep and Broad AP Offering

At the high school level, ISSH offers 23 Advanced Placement (AP) courses — an unusually comprehensive catalogue for a school of approximately 585 students. Subjects span English Language and Composition, English Literature, Computer Science A, Biology, Chemistry, Physics I and II, Calculus AB and BC, Statistics, French Language, Japanese Language, World History, European History, 2D and 3D Art & Design, Music Theory, Macroeconomics, Microeconomics, AP Seminar, and AP Research.

This breadth allows students to pursue genuine depth in their areas of interest, whether they are aspiring scientists, artists, economists, or writers. The AP Capstone program (Seminar + Research) is particularly noteworthy, as it trains students in independent research, academic writing, and scholarly presentation — skills that translate directly to university success.

Outstanding Results

The school's AP outcomes data (from the 2020-21 school profile) is striking:

• 2018: 65 of 70 students scored 3 or above — a 92.9% pass rate
• 2019: 73 of 79 students scored 3 or above — a 92.4% pass rate
• 2020: 100 of 100 students scored 3 or above — a 100% pass rate

In 2020, 46% of exam scores were 5s (the maximum), and 69% were 4 or above. The average AP score that year was 4.11, placing ISSH well above the global average of approximately 2.9. A total of 61 AP Scholars (students averaging 3.5 or above across multiple exams) were recognized in 2020.

What This Means for University Admissions

Strong AP results translate directly into university admissions advantages, particularly for US institutions. ISSH graduates go on to universities including Harvard, Yale, UC Berkeley, University of Toronto, University of Melbourne, and Tokyo University, among others. The 100% university acceptance rate, combined with AP results of this caliber, positions ISSH graduates as highly competitive candidates at selective institutions worldwide.

Location and Atmosphere

Nestled in the Hiroo district of Shibuya-ku, the ISSH campus is described as a peaceful, tree-lined space that feels removed from the bustle of central Tokyo — yet sits just one minute on foot from Hiroo Station on the Tokyo Metro Hibiya Line. This combination of accessibility and calm is unusual for a central Tokyo school and is frequently cited as one of the campus's defining qualities.

The neighborhood itself is significant. Hiroo is one of Tokyo's most internationally oriented residential areas, home to numerous foreign embassies, international supermarkets, and a large expatriate community. Students arriving from abroad quickly find themselves in a community that feels familiar, while still being immersed in Japanese culture.

Facilities

Despite its urban location, ISSH offers a surprisingly comprehensive range of facilities:

• Sports: Indoor gymnasium, artificial turf (AstroTurf) field, and tennis courts
• Performing Arts: Multipurpose drama/assembly hall, orchestra and choir practice rooms, music practice rooms
• Visual Arts: Art studios, ceramics workshop
• STEM: Science laboratories, food technology kitchen
• Community: Chapel (used for assemblies and spiritual events), junior school playground
• Academic: Library, standard classrooms

The food technology kitchen and ceramics studio speak to ISSH's commitment to practical, hands-on learning beyond traditional academics. The chapel anchors the community spiritually and serves as a gathering point for school ceremonies.

Daily Life on Campus

The school runs a 2-semester academic year beginning in late August and ending in early June. Students in Grades 1–12 follow a predominantly female-only academic environment (K3–K5 is coeducational), which the school maintains is conducive to confident self-expression and leadership development. Lunch is available through an optional catering service (Cezar's Kitchen bento delivery), and the school requires a uniform — a distinctive green check skirt design.

A Genuinely International Community

ISH's approximately 585 students represent around 50 nationalities, making it one of Tokyo's most diverse international schools relative to its size. This diversity is not incidental — it is central to the school's educational mission. The Sacred Heart philosophy explicitly values the building of community across difference, and this shows in how the school structures student life.

Service as a Core Pillar

Service learning is embedded throughout the curriculum and co-curriculum at ISSH. The school runs a well-developed Social Service Council at the high school level, and the entire school participates in events such as the annual Rice Drive (a food donation campaign). Students organize charity fundraisers, community clean-ups, and awareness campaigns from a young age.

At the club level, organizations like Amnesty International, the Animal Rights Club, the Global Issues Network, and Youth Impact Club channel student energy into real-world action. The GSA (Gay-Straight Alliance) reflects the school's commitment to inclusive community values.

Global Competencies Through Competition

ISH students regularly participate in the Kanto Plain Association of Secondary Schools (KPASS) competitions in athletics, music, and performing arts, as well as Model United Nations (MUN) conferences, the Speech Festival, and Debate competitions. These activities build public speaking, critical thinking, and collaborative skills that complement the AP academic program.

Parent and Family Engagement

The school holds an annual Family Festival and regular open house events for prospective families. Parents are expected to have at least one English-proficient member, reflecting the school's commitment to maintaining a coherent English-medium community. School tours are available on Thursday mornings throughout the year, and the admissions team is accessible via both email ([email protected]) and phone.

A Community for the Long Term

Many ISSH families are long-term Tokyo residents — embassy staff, corporate expatriates, and Japanese returnee families — who value the continuity and stability the school provides. The tight-knit community, small class sizes (averaging 20–23 students), and low student-teacher ratio (approximately 7:1) mean that students are known individually and supported throughout their time at the school.

Admissions Overview

The International School of the Sacred Heart (ISSH) operates a rolling admissions model, accepting applications year-round for the following school year. Applications open each September and are processed as they arrive, allowing families to apply up to 12 months before intended enrollment. However, the school strongly recommends finalizing applications by early December for Grades 1–12 to secure consideration for available seats.

Application Timeline

Kindergarten (K3–K5) follows a more structured timeline compared to upper grades:

• Kindergarten 3–4 (ages 3–4): First-round application deadline was December 12, 2025, with interviews conducted January–February 2026. A possible second interview round may occur in March 2026 if spaces become available.

• Kindergarten 5 (age 5): Features a priority application period from September 1 to November 14, 2025, followed by group screening on January 10, 2026. Candidate interviews take place January–February 2026, with enrollment decisions issued by February 2026.

Grades 1–12 operate on the standard rolling basis, though early submission is advantageous given space limitations.

Application Requirements

Financial Commitment

Before beginning the application process, families must pay a ¥30,000 non-refundable application fee via bank transfer. This fee applies to each applicant and must be paid before accessing the online Veracross application portal.

• Family support for the school's values-driven education
• Willingness to engage in service learning and social justice initiatives

Diversity Goals

The school actively seeks cultural and ethnic diversity in each grade, aiming for a balance of language proficiencies and international perspectives across its 50+ represented nationalities.

Nationality Requirements

Critical eligibility rule: For Grades K3–9, either the student or one parent must hold a non-Japanese passport. Students with only Japanese nationality (and Japanese-only parents) are eligible only for Grades 10–12. This policy reflects ISSH's mission to serve the international expatriate community.

Priority & Waiting Pool

Admissions Priority

Siblings of currently enrolled students and children of alumnae receive priority consideration over other applicants, provided:

• Space is available in the desired grade
• The candidate passes standard screening and interview processes

When a grade level or the ELA programme reaches capacity, qualified applicants are placed in a waiting pool for that specific school year. Important details:

• Placement lasts only through the applied school year
• Families must reapply for subsequent years if still interested
• No tuition deposits or spots are held beyond the initial application year
• The school contacts families if spaces open

Practical Requirements

Kindergarten Readiness

Students applying to Kindergarten (K3–K5) must be fully toilet-trained by August 1 before school entry. No diapers or pull-ups are permitted at school.

Gender Policy

Boys are accepted only in Kindergarten 3–5 (ages 3–5). From Grade 1 onward, ISSH is an all-girls school.

Application Strategy Tips

Early submission is advantageous: While admissions are rolling, applying early in the cycle (September–December) maximizes chances for available seats.

Prepare English documentation: International families should budget time for professional translation of academic records.

Understand the values framework: Families should research and genuinely align with Sacred Heart Goals, as values fit is a significant selection factor.

Consider ELA limitations: Students requiring intensive English support should apply to lower grades where ELA services are more readily available.

Plan for multiple steps: The process includes payment, document submission, screening tests, and family interviews—typically spanning 2–3 months.

No feedback or appeals: Admissions decisions are final; families should have backup school options.

Contact & Next Steps

Prospective families are encouraged to:

• Attend school tours and information sessions
• Contact the Director of Admissions with specific questions
• Review the complete application checklist on the Veracross portal
• Submit applications well before desired enrollment dates

ISSH's thorough admissions process ensures that accepted students can thrive academically, embrace the school's values-driven mission, and contribute to its diverse international community.

University Placement Overview

Academic Preparation

Advanced Placement Program

ISSH's university placement success is underpinned by an exceptionally broad Advanced Placement curriculum offering 22 AP courses across all major disciplines:

STEM Subjects:

• AP Biology
• AP Chemistry
• AP Physics
• AP Calculus AB and BC
• AP Statistics
• AP Computer Science

Languages and Humanities:

• AP English Language and Composition
• AP English Literature
• AP Japanese

• AP European History

Arts:

• All three AP Studio Art courses
• AP Music Theory

Social Sciences:

• AP Macroeconomics
• AP Microeconomics

AP Capstone:

• AP Seminar
• AP Research

This comprehensive AP offering is notably broad for a school of ISSH's size (approximately 585 students), providing students with college-level rigor and the opportunity to earn advanced standing at universities worldwide.

AP Examination Performance

In May 2024, ISSH's AP results demonstrated strong academic preparation:

• Approximately 100 students took AP examinations
• Total of roughly 300 AP exams administered
• 100% of candidates scored 3 or above (the College Board's benchmark for college credit eligibility)

This perfect pass rate indicates that virtually all ISSH students taking AP courses reach college-level mastery of the material. While the school does not publicly report the breakdown of scores 4 and 5, the universal achievement of qualifying scores suggests effective instruction and appropriate course placement.

College Counseling Support

Individualized Guidance

ISSH provides comprehensive, personalized college counseling:

• Grade 10: Students meet with school leadership and college counselors to begin planning senior-year course selection
• Peer Consultation: Grade 10 students consult with current seniors about AP course choices and workload management
• Ongoing Support: Dedicated college counseling program guides students through application planning, essay writing, and university matching

This multi-year, individualized approach ensures students build appropriate academic profiles and apply to universities well-matched to their goals and abilities.

Curriculum Alignment

While ISSH does not offer the International Baccalaureate (IB) Diploma despite its Sacred Heart network heritage, the school's AP-focused approach has proven highly effective for university placement. The AP curriculum's flexibility allows students to pursue deep specialization in areas of strength while meeting broad liberal arts requirements.

Graduation and Matriculation Rates

ISSH reports that all graduates proceed to tertiary education, reflecting an effective 100% graduation rate combined with 100% university enrollment. This outcome indicates:

• Strong student retention through Grade 12
• Effective academic support preventing dropout
• Universal college-going culture
• Successful preparation meeting university admissions standards globally

No gap-year statistics are provided, suggesting most students proceed directly to university enrollment.

All-Girls Advantage

The school emphasizes that its all-girls environment (Grades 1-12) contributes to university placement success by:

• Building confidence in academic risk-taking
• Encouraging leadership development
• Supporting STEM participation without gender stereotyping
• Fostering "girls take center stage" mentality that translates to university success

ISSH's philosophy holds that this single-sex environment prepares students to advocate for themselves and pursue any academic direction without limitations.

Comparison Context

While specific university matriculation data (percentage attending each institution) is not published, the breadth of acceptances spanning Ivy League schools, Oxbridge, top Japanese universities, and selective institutions across multiple countries demonstrates that ISSH students compete successfully in diverse admissions landscapes.

The 100% acceptance rate should be understood in context: students receive counseling to apply to appropriate-reach, match, and safety schools, and the supportive environment likely encourages realistic list-building rather than purely aspirational applications.

Scholarships and Recognition

The research data does not detail merit scholarships or honors awarded to graduating students by universities. However, acceptance to highly selective institutions (Harvard, Cambridge, etc.) implies some graduates likely receive merit recognition and financial aid from their chosen universities.

Limitations and Considerations

Prospective families should note:

• Detailed matriculation data (where students actually enroll versus acceptance offers) is not published
• No breakdown of acceptances by academic major or field of study
• Merit scholarship data from universities not disclosed
• Sample sizes are relatively small given ISSH's enrollment (graduation classes likely 40-60 students)

Despite these limitations, the consistent pattern of acceptances to top-tier global universities over multiple years provides strong evidence of effective university preparation and counseling.

Overview

The International School of the Sacred Heart (ISSH) cultivates a distinctive educational community centered on its all-girls model, international diversity, and Catholic-rooted values. With approximately 585 students representing around 50 nationalities and 15+ religious or belief traditions, the school creates a globally-minded environment where girls take center stage academically and socially. While Catholic in heritage through the Society of the Sacred Heart, ISSH welcomes families of all faiths and operates as an inclusive international school.

Student Body Composition

Demographics and Diversity

ISSH serves a highly international student population spanning ages 3-18 across four divisions: Pre-Kindergarten (K3-K5, co-educational), Junior School (Grades 1-4), Middle School (Grades 5-8), and High School (Grades 9-12). The school is exclusively for girls from Grade 1 onwards, with boys accepted only in the co-educational kindergarten years.

The student body's international character is intentional and protected by admissions criteria. For Grades 9 and below, either the student or one parent must hold a non-Japanese passport. Students with only Japanese passports are eligible only for Grades 10-12. This policy ensures the school maintains its expatriate-focused mission of serving daughters of foreign nationals for whom the Japanese education system is not viable.

Nearly all families are internationally mobile expatriates, creating a transient but tightly-knit community. The diversity extends beyond nationality to include multiple religious and belief systems, though all families must support the school's Sacred Heart Goals and Criteria.

Educational Philosophy and Values

Sacred Heart Goals Framework

ISSH's educational approach is grounded in five Sacred Heart Goals that shape daily life and learning:

Goal 1: A Personal and Active Faith in God
Goal 2: Deep Respect for Intellectual Values
Goal 3: Social Awareness Which Impels to Action
Goal 4: Building Community as a Christian Value
Goal 5: Personal Growth in an Atmosphere of Wise Freedom

These goals translate into a curriculum that cultivates strong belonging, critical thinking about global issues, and service as a natural part of life. The school emphasizes developing the whole person—intellectual, spiritual, physical, and emotional dimensions—preparing students to become confident, inspirational, and transformational leaders.

Religious Identity and Inclusion

Despite its Catholic heritage, ISSH does not offer religious instruction or require mass attendance. Instead, the school teaches a secular Values programme exploring ethics, world religions, and personal responsibility. This approach honors the Sacred Heart tradition while remaining inclusive of all faiths represented in the student body.

Symbolic religious elements include a weekly Still Point meditation session on Wednesday mornings and Thursday morning prayer services, both designed for inclusive participation and quiet reflection rather than religious instruction.

The All-Girls Advantage

Confidence and Leadership

ISSH explicitly positions its all-girls environment as a key strength. The school asserts that girls at ISSH take center stage, building confidence in leadership and academic risk-taking without competing for attention or opportunities with male peers. This single-gender model aims to cultivate an atmosphere of wise freedom where students develop into leaders who pursue their talents in whatever direction they choose.

The school has operated as an all-girls institution since 1908 and maintains this tradition as central to its mission of developing confident, independent thinkers.

Community Engagement

Parent Involvement

Family engagement is deeply embedded in school culture. ISSH maintains active communication through bi-weekly newsletters from each division principal and a monthly Head of School newsletter. The Parents Association (PA) plays a central role, organizing events, orientations, coffee mornings, and fundraisers throughout the year.

Parents routinely attend assemblies, parent-teacher conferences, and school ceremonies, creating multiple touchpoints between home and school. The PA works closely with administration to bring families together, fostering the tight-knit community ethos that defines ISSH. At least one parent must be proficient in English (able to speak and read comfortably) to support their daughter's education in this English-medium environment.

Alumni Connections

Former students emphasize lifelong friendships and an extended family feeling among Sacred Heart graduates. The school's connection to the global network of 150+ Sacred Heart schools worldwide provides additional identity connection and cultural exchange opportunities that extend well beyond graduation.

Extracurricular Life

Athletics

As a member of the Kanto Plain Association of Secondary Schools (KPASS), ISSH fields competitive sports teams across six sports in three seasons. The school maintains A/B and JV/Varsity teams to ensure players of all skill levels can participate. Beyond KPASS sports, students access niche offerings including fencing and Japanese ekiden (long-distance relay races).

Arts and Performance

The fine arts represent a hallmark of ISSH culture. The school supports multiple choirs, each with 70-80 members, a full orchestra, and even a student-led rock band that annually records an album and video and performs at school events. ISSH hosts KPASS arts events including the Artscape visual arts exhibition and drama festivals. High school students can pursue all three AP studio art courses, AP Music Theory, and various drama and performance electives.

Academic Competitions and Clubs

Students participate in Model United Nations, debate team, Brain Bowl, math competitions, and speech contests. The school fields a VEX robotics team with a record of awards and trophies since its inception.

Service and Social Awareness

Aligning with Sacred Heart Goal 3 (social awareness which impels to action), ISSH offers diverse service-oriented clubs including:

• Amnesty International (human rights advocacy)
• TASSEL (language teaching charity supporting education in Cambodia)
• GSA (LGBTQ+ advocacy group)
• Support for Nepal SEEDS (an NGO in Nepal)

These opportunities reflect the school's commitment to service as a natural part of life and preparing students to engage meaningfully with global challenges.

Student Leadership

ISSH maintains a robust student government structure with over 30 elected leadership positions annually, spanning Academic, Arts, Sports, Social Service, and World Councils, plus grade-level representatives. Leadership opportunities begin in Grade 9 and continue through graduation.

The school encourages student initiative: any student can pitch a club idea to faculty, and if approved, it becomes an official student-led club. This system empowers students to shape their own community and pursue their interests.

Pastoral Care and Wellbeing

Support Systems

ISSH provides comprehensive pastoral care through multiple layers:

Homeroom System: Every student is assigned to a homeroom (typically two per grade) where the homeroom teacher monitors integration and wellbeing. Homerooms meet daily for announcements and community building.

New Student Support: Orientation programs and peer-support systems, including High School Peer Support leaders, help newcomers acclimate to the school community.

Counseling: A school counselor is available to support student mental health and wellbeing.

Grade-Level Excursions: Annual three-day overnight trips for Grades 5-12 foster friendship and cultural exposure to Japan, providing opportunities to explore the country both geographically and culturally.

Community Integration

The transient nature of the international community makes integration support especially important. ISSH's pastoral care framework ensures that new families feel welcomed and that students build meaningful connections despite the community's mobility.

School Motto and Identity

ISSH's culture centers on its motto emphasizing Community, Confidence, and Courage. These three pillars manifest in:

• Community: The diverse, supportive environment where 50 nationalities learn together
• Confidence: The all-girls model that puts young women center stage in all activities
• Courage: The values-driven education that prepares students to be transformational leaders

This identity, combined with rigorous academics, diverse international exposure, and values-focused enrichment, defines the ISSH educational experience and distinguishes it within Tokyo's international school landscape.

Complete Cost Breakdown

One-Time Enrollment Fees

Families enrolling at the International School of the Sacred Heart face substantial upfront costs totaling ¥930,000 per student:

• Application Fee: ¥30,000 (non-refundable, paid before application submission)
• Registration Fee: ¥300,000 (non-refundable, one-time at enrollment)
• Educational & Building Development Fee: ¥600,000 (non-refundable, one-time at enrollment)

These fees are standard for all students regardless of grade level and represent a significant initial investment that families must budget for before their child begins classes.

Annual Tuition (2026-2027)

Tuition varies by grade level, with higher grades commanding higher fees:

All students also pay an annual Building/Maintenance Fee of ¥220,000 (non-refundable), which is charged each year in addition to tuition.

First-Year Total Investment

For a family enrolling one child, the first-year costs are substantial:

• Kindergarten 3-4: ¥3,710,000 (¥930K fees + ¥2,560K tuition + ¥220K maintenance)
• Elementary (Grades 1-8): ¥3,920,000 (¥930K fees + ¥2,770K tuition + ¥220K maintenance)
• High School (Grade 9): ¥3,940,000 (¥930K fees + ¥2,790K tuition + ¥220K maintenance)
• Senior Year (Grade 12): ¥4,030,000 (¥930K fees + ¥2,880K tuition + ¥220K maintenance)

Subsequent years eliminate the one-time enrollment fees but retain the annual tuition plus maintenance fee.

Additional Costs to Consider

School Uniforms

Students in Grades 1-12 are required to wear full uniforms daily. While ISSH does not publish uniform costs on its website, families should budget for:

• Initial uniform purchase (multiple sets recommended)
• Replacement items as children grow
• Seasonal variations (summer/winter uniforms)
• Physical education uniforms
• Kindergarten students require a school smock

Uniform costs are not included in tuition and represent an additional out-of-pocket expense.

Optional Services

Hot Lunch Program: ISSH offers an optional daily hot lunch service through Cezar's Kitchen. Parents can purchase lunches individually (pricing not published), with vegetarian options and "Meat-Free Monday" available. Kindergarten students receive lunch in the classroom, while older students may purchase from the cafeteria. Families choosing not to participate must provide packed lunches.

Extended Day Program: For Kindergarten and Junior School families needing after-school care, ISSH offers supervision until 6:00 PM. The program charges a flat fee per semester (specific amounts not published) and includes homework time and supervised play.

Transportation: ISSH does not operate a school bus service. Families must arrange their own transportation, typically via Tokyo public transit or personal vehicles. The school offers bicycle parking on campus.

Academic and Extracurricular Expenses

Standardized Testing: High school students taking AP exams incur College Board fees (approximately $95-100 USD per exam, or roughly ¥13,000-14,000). With 22 AP courses offered and students typically taking 4-8 AP exams during junior and senior years, testing fees can total ¥50,000-110,000 over two years.

Grade-Level Excursions: Annual overnight trips for Grades 5-12 (3-day cultural excursions within Japan) require additional payment. Costs vary by destination but are not included in tuition.

Materials and Supplies: While textbooks and classroom materials appear to be covered within tuition (no separate technology or textbook fees are published), families may need to purchase supplementary materials or supplies for specific courses.

Multi-Child Cost Implications

No Sibling Discounts

ISsH does not offer sibling tuition discounts. Families with multiple children pay full tuition and fees for each enrolled student. While siblings of current students receive admissions priority, this preference does not extend to financial relief.

For a family enrolling two children simultaneously:

• Two elementary students (Grades 1-8): First-year total = ¥7,840,000
• Ongoing annual costs (two students): ¥5,980,000 per year

This represents a significant financial commitment for multi-child families.

Financial Aid Options

Need-Based Scholarships Only

ISsH offers limited need-based financial assistance through the Sister Culhane and d'Huart Scholarship Funds. These scholarships were established to support "students each year for whom paying full tuition would be prohibitive."

Important limitations:

• No merit-based scholarships are offered
• No academic performance scholarships
• No multi-child family discounts
• Application criteria, eligibility thresholds, and award amounts are not publicly disclosed
• Interested families must contact the school directly for information

The limited scope of financial aid means most families should plan to pay full tuition unless facing genuine financial hardship.

Payment Terms

All tuition and fees must be paid in advance via bank transfer before the school year begins. For students enrolling mid-year, tuition is prorated and charged quarterly. There are no published installment payment plans, suggesting families must have substantial liquid assets available at enrollment.

Comparative Context

Compared to other Tokyo international schools:

• American School in Japan (ASIJ): ¥3,425,000-¥3,533,000 for Grades 6-12 (higher than ISSH)
• Seisen International School: ¥2,650,000 (Grades 1-5) and ¥2,700,000 (Grades 6-12) (slightly lower than ISSH)

ISsH's tuition of ¥2,770,000-¥2,880,000 positions it in the moderate-to-high range for Tokyo international schools—less expensive than the larger co-educational schools like ASIJ but comparable to similar all-girls Catholic international institutions like Seisen.

Total 13-Year Cost Estimate

For a student attending ISSH from Kindergarten 3 through Grade 12 graduation:

• One-time fees: ¥930,000
• 10 years at lower tuition (K3-K5, Grades 1-8): approximately ¥27,000,000
• 4 years at higher tuition (Grades 9-12): approximately ¥11,260,000
• 13 years of maintenance fees: ¥2,860,000
• Estimated total: ¥42,050,000 (approximately $280,000-300,000 USD at current exchange rates)

This estimate excludes uniforms, lunch, testing fees, trips, and other incidental costs, which could add ¥500,000-1,000,000 over 13 years.

Budget Planning Recommendations

Families considering ISSH should:

1. Prepare liquid assets of ¥4-5 million for first-year enrollment (one child)
2. Budget ¥3+ million annually for ongoing tuition and fees per child
3. Add 10-15% for uniforms, lunch, trips, and testing
4. Investigate corporate sponsorship if relocating for work (many expatriate families receive education allowances)
5. Contact admissions early if financial aid may be necessary, as the scholarship fund is limited
6. Plan for currency fluctuations if earning in non-yen currencies

The total cost of an ISSH education represents a significant investment, positioning the school as accessible primarily to upper-middle-class and affluent families, expatriates with corporate education benefits, or those willing to prioritize education spending above other expenses.

Ideal Student Profile

Academic Background

ISSH is best suited for academically capable girls who can thrive in a rigorous, college-preparatory environment. The school offers 22 Advanced Placement courses and reports that 100% of AP test-takers score 3 or above, reflecting high academic standards. Students should arrive with solid foundational skills and a willingness to engage in challenging coursework, particularly as they progress toward the AP-heavy junior and senior years.

The school achieves 100% university acceptance annually, with graduates matriculating to top-tier institutions including Harvard, Yale, Brown, Cornell, University of Pennsylvania, UC Berkeley, Cambridge, UCL, University of Tokyo, and Waseda. Students targeting competitive universities in the U.S., U.K., Canada, or Asia will find ISSH's college counseling program and AP curriculum well-aligned with their goals.

Language Requirements

English proficiency is essential. At least one parent must be able to speak and read English comfortably, as all school communications and the educational program are conducted in English. Students must have sufficient English to access the curriculum:

• Elementary/Middle School: Basic English literacy required; limited English Language Acquisition (ELA) support available on a space-available basis
• High School (Grades 9-12): Independent English proficiency required; ELA support not offered at upper levels
• Grade 10+: Students must enter with at least intermediate English skills

Non-native English speakers can be considered for the ELA program in lower grades, but families should understand that English support is limited and students are expected to transition to mainstream classes relatively quickly.

Nationality and Residency

ISSH primarily serves internationally mobile expatriate families. The school explicitly notes it was founded for "daughters of foreign nationals for whom the Japanese education system is not a viable option." Key eligibility requirements:

• Grades K3-9: Student OR at least one parent must hold a non-Japanese passport
• Grades 10-12: Japanese nationals may apply (even if both parents are Japanese)
• The school serves approximately 585 students representing 50 nationalities

Families on diplomatic assignments, international corporate postings, or long-term expatriate placements in Tokyo form the core community. Dual-national families are welcome, but those seeking a Japanese-language education or Japanese national curriculum should look elsewhere.

Family Values and Philosophy Fit

Sacred Heart Values Alignment

Families who resonate with the Sacred Heart Goals and Criteria will find the strongest cultural fit. While ISSH is Catholic in heritage, it welcomes all faiths and does not require religious observance or mass attendance. Instead, the school emphasizes:

• Personal and active faith (in one's own tradition)
• Intellectual values and academic excellence
• Social awareness and service to others
• Community building across differences
• Personal growth in an atmosphere of wise freedom

The admissions committee explicitly considers "alignment of family values with the Sacred Heart Goals and Criteria" as a selection factor. Families who prioritize service learning, social justice, ethical leadership, and whole-child development over purely academic metrics will appreciate ISSH's values-driven approach.

All-Girls Environment

ISSH is an all-girls school from Grade 1-12 (boys are accepted only in co-educational kindergarten K3-K5). The school frames this as a strategic advantage, noting that girls "take center stage" and develop confidence, leadership skills, and academic risk-taking in an environment free from gender-based stereotypes.

Ideal families:

• Value single-gender education and its developmental benefits
• Seek an environment where daughters can assume all leadership roles
• Want their daughters to pursue interests in STEM, arts, sports, and humanities without gender limitations
• Appreciate the global Sacred Heart network of 150+ schools and alumnae connections

Families expecting or preferring co-educational settings should consider other Tokyo international schools.

Student Characteristics That Thrive

Leadership and Community Engagement

ISSH offers over 30 elected student leadership positions across Academic, Arts, Sports, Social Service, and World Councils. Students who are:

• Naturally curious and independent thinkers
• Interested in social justice, human rights, or community service
• Eager to start clubs or initiatives (students can pitch and launch their own clubs)
• Comfortable taking on leadership responsibilities from Grade 9 onward

will find abundant opportunities to grow.

Extracurricular Breadth

The school suits students with diverse interests beyond academics:

• Athletes: KPASS member with A/B and JV/Varsity teams across six sports, plus niche offerings like fencing and ekiden
• Artists and musicians: Multiple choirs (70-80 members each), full orchestra, student rock band, all three AP studio art courses, drama, and visual arts
• STEM enthusiasts: VEX robotics team, math competitions, Brain Bowl
• Advocates and activists: Model UN, debate, Amnesty International, LGBTQ+ advocacy (GSA), language-teaching charity work

Social and Emotional Readiness

ISSH maintains a comprehensive pastoral care system with daily homeroom meetings, peer support programs, and a school counselor. Students who will thrive:

• Can adapt to a diverse, multicultural environment (50 nationalities, 15+ religious traditions)
• Are comfortable with frequent transitions (expatriate families often move)
• Appreciate reflective practices (weekly "Still Point" meditation sessions, values curriculum)
• Benefit from structured support while exercising "wise freedom"

Who May Struggle or Find a Mismatch

Limited Support Services

ISSH is not equipped for extensive special education needs. The school explicitly states that applicants requiring services beyond its capacity (academic or behavioral) may not be admitted or may be counseled to withdraw. Families seeking:

• Dedicated learning disabilities support beyond middle school
• Extensive ESL/ELA beyond elementary levels
• Behavioral intervention programs
• Significant academic accommodations

should inquire carefully about available support before applying.

Cultural and Structural Preferences

Students and families who may not fit:

• Strongly prefer co-education: ISSH is single-gender from Grade 1 onward
• Seek Japanese curriculum: The school offers an international, English-medium program; Japanese is taught as a subject but not the instruction language
• Need extensive financial aid: Only the Sister Culhane and d'Huart need-based scholarships are available; no merit scholarships or multi-child discounts are offered
• Cannot meet English requirements: Both student and at least one parent must be English-proficient
• Want IB Diploma: ISSH offers only AP curriculum, not IB

Practical Considerations

• No school bus service: Families must arrange transportation via public transit or private means
• Boys above kindergarten: Not accepted after Grade K5
• Mid-year transfers: Limited availability; rolling admissions prioritizes early applicants
• Toilet training: K3-K5 applicants must be fully toilet-trained by August 1 before enrollment

Special Admissions Considerations

Priority Groups

Siblings of current students and children of alumnae receive admissions priority (not guaranteed admission) over other candidates, subject to passing screening and interviews. Families with existing Sacred Heart connections globally may find cultural continuity appealing.

Financial Profile

With annual tuition ranging from ¥2,560,000 (K3-4) to ¥2,880,000 (Grade 12), plus ¥900,000 in one-time enrollment fees (registration + development fee) and ¥220,000 annual building/maintenance fees, ISSH requires significant financial investment. Families should budget for:

• Uniforms (required Grade 1+)
• Optional hot lunch program
• Extended Day Program (if needed for K-Grade 4)
• Grade-level overnight excursions
• Standardized test fees (AP, TOEFL, etc.)

The school is best suited to families with stable employment benefits or international relocation packages that cover international school tuition.

Bottom Line

The International School of the Sacred Heart is ideal for globally mobile families with academically capable daughters who value:

• Rigorous college preparation (especially for U.S./U.K. universities)
• All-girls education with strong leadership development
• Values-based community with service and social justice emphasis
• Diverse, multicultural environment
• English-medium instruction with Japanese or French language study
• Access to the global Sacred Heart network

Families seeking co-education, extensive learning support, IB curriculum, or Japanese-language instruction should explore other options. Those aligned with Sacred Heart values and comfortable with the all-girls model will find a supportive, academically excellent community preparing students for top universities worldwide.
