The International School of the Sacred Heart (ISSH) is guided by the Sacred Heart tradition, which blends rigorous academics with character formation and service. The school emphasizes five goals often associated with Sacred Heart education: a personal and active faith, intellectual values, social awareness that impels to action, building of community, and personal growth. In practice, this means classrooms that cultivate inquiry and critical thinking, counseling that nurtures wellbeing, and age-appropriate service learning that ties compassion to concrete action.

Is ISSH only for Catholic students?

No. While ISSH is a Catholic girls’ school, it welcomes students of all faiths and those with no religious affiliation. Prayer services, liturgies, retreats, and religion classes are designed to be inclusive and respectful. The goal is not proselytization, but the development of conscience, reflection, and a commitment to justice—values that resonate across cultures and beliefs.

What grades and age levels does ISSH serve?

ISSH typically enrolls students from early years through Grade 12. The program is organized into developmental divisions (early childhood/elementary, middle school, and high school) to align academic expectations and pastoral care with each stage of growth. Families can apply for entry at multiple points, though early years and Grade 9 are common intake levels.

What curriculum does the high school follow?

The high school offers a college-preparatory, standards-based curriculum taught primarily in English. Students build a strong foundation in English, mathematics, sciences, social studies, world languages, and the arts. Advanced and honors pathways may include externally recognized options such as Advanced Placement-style coursework, alongside electives in technology, design, and the creative arts. Academic counseling guides students in choosing courses that match interests, challenge level, and university ambitions.

How strong are university outcomes for ISSH graduates?

Graduates matriculate to a wide range of universities worldwide, including institutions in North America, Europe, Asia, and Oceania. Outcomes reflect personalized counseling, coherent course planning, and a profile that highlights leadership and service. ISSH encourages students to develop authentic portfolios—capstone work, arts performances, research projects, and community initiatives—that help applications stand out beyond test scores.

What is the approach to student wellbeing and pastoral care?

Wellbeing is woven into daily life. Homeroom teachers and counselors monitor academic progress and social-emotional health, while advisory periods address topics such as study skills, digital citizenship, friendships, and stress management. Age-appropriate retreats and reflection days give students space to process experiences. The school partners closely with families and, when needed, external specialists to provide layered support.

Which languages are offered, and do students learn Japanese?

English is the language of instruction, and students typically study Japanese as a host-country language to support integration into life in Tokyo. Additional world languages may be available as students move into higher grades. Language placement considers prior exposure, proficiency, and long-term goals, and support is available for English language learners to ensure access across the curriculum.

What co-curricular activities can students join?

ISSH offers a broad co-curricular program to encourage balanced growth. Teams and clubs commonly include volleyball, basketball, soccer, track and field, music ensembles, choir, theater productions, visual arts studio, STEM/robotics, debate, Model United Nations, student council, service clubs, and culture or language societies. Participation fosters leadership, time management, and friendship across grade levels.

How does service learning work at a Sacred Heart school?

Service is not an add-on; it is curricular. Students examine local and global issues, connect them to coursework, and design age-appropriate actions—fundraising for partner organizations, volunteering with community groups, environmental projects, or awareness campaigns. Reflection is essential: students analyze root causes, personal impact, and ethical dimensions, developing empathy and a lifelong habit of responsible citizenship.

What are the campus facilities like?

The campus supports both study and creativity. Typical facilities include bright classrooms with modern displays, science and computer labs, a library and media center, makerspaces or design labs, music rooms, art studios, a chapel, a gymnasium and outdoor athletics areas, and spaces for performances and assemblies. Technology access and safe, supervised common areas allow students to collaborate and explore interests responsibly.

How are new students supported during transition?

Transitions are guided with care. Orientation sessions help students and families understand routines, expectations, and support systems. Buddy programs pair new students with classmates who can answer questions and model school culture. Counselors monitor academic load and social integration during the first semester, and teachers provide targeted feedback to build confidence quickly.

What is the admissions process like?

Admissions typically involves an online application, school records, teacher recommendations, and age-appropriate assessments or interviews. ISSH evaluates readiness for an English-medium, college-prep environment as well as the family’s alignment with the school’s mission. Because places can be limited, families are encouraged to apply early and provide complete documentation to facilitate timely review.

Does the school offer financial assistance?

Some international schools provide limited financial support, such as need-based aid or partial tuition assistance. Availability and criteria vary by year and applicant profile. Families should consult the latest admissions materials, deadlines, and required forms, and be prepared to share financial documentation in confidence for equitable assessment.

How does ISSH communicate with parents?

Clear communication is a hallmark of the home–school partnership. Parents can expect regular newsletters, a parent portal or learning management system for assignments and grades, teacher emails, and scheduled conferences. Many classes use transparent rubrics and formative feedback so families can see not just final grades but the learning journey and next steps.

What is the homework and assessment philosophy?

Homework is calibrated for purpose and age, emphasizing retrieval practice, independent reading, skill reinforcement, and long-term projects rather than busywork. Assessment blends formative checks for understanding with summative tasks—essays, labs, presentations, performances, and exams. Students receive actionable feedback aligned to standards, and opportunities for revision promote growth mindset over perfectionism.

Is transportation or school lunch available?

International schools in Tokyo often coordinate optional bus routes depending on demand and location; availability can change yearly. Food options may include a cafeteria, meal vendors, or space for students to bring packed lunches. The school prioritizes allergies and dietary needs with clear labeling and communication protocols. Families should review current-year offerings during enrollment.

How does the school ensure safety and digital responsibility?

Safety includes campus access controls, trained supervision, drills, and child protection policies. Digital responsibility is taught explicitly: acceptable-use agreements, media literacy, citation ethics, cyberbullying prevention, and healthy screen habits. Classroom devices are used for purposeful learning, with filters and monitoring that balance freedom to explore with a duty of care.

What makes an all-girls environment distinctive?

Research suggests that girls’ schools can amplify student voice, reduce stereotype threat in STEM fields, and increase participation in leadership roles. In practice, ISSH classrooms are designed to invite risk-taking, thoughtful debate, and ambition without social penalties. Athletics, arts, and student government provide plentiful opportunities to lead and to see women leading.

How can families engage with the community?

Parent–teacher associations, volunteer committees, and cultural events strengthen the sense of belonging. Families often support school productions, service drives, and international festivals. Workshops—on adolescent development, university planning, or digital wellness—equip parents to partner effectively with the school during key milestones.

What tips help applicants present a strong application?

Start early, read requirements carefully, and tell your story. Share report cards that reflect consistent effort, teacher recommendations that speak to character and collaboration, and any evidence of initiative—clubs started, competitions entered, or service projects led. If English is a second language, include results from recognized proficiency tests if requested, and be candid about support needs so the school can plan appropriate scaffolds.

How does ISSH support diversity and global citizenship?

Diversity is a daily reality on campus, and the curriculum treats it as a strength. Literature, history, and social studies courses foreground multiple perspectives; student clubs celebrate languages and cultures; and global issues—climate, migration, public health—are approached with data, empathy, and action. The goal is not only to understand the world but to improve it.

What should families know about life in Hiroo and Tokyo?

Hiroo is a well-connected, international neighborhood with embassies, parks, and cafés within walking distance. Public transit makes commuting straightforward, and students benefit from cultural institutions across the city—museums, universities, and performance venues—often integrated into fieldwork and excursions. The location enriches learning and offers safe, convenient access to world-class resources.

How can we learn more or visit the campus?

Prospective families typically begin with an inquiry form and attend information sessions or open days. Campus tours (in-person or virtual) allow families to see facilities, observe classes when possible, and meet students and staff. If you cannot attend in person, request a meeting with admissions and counseling to discuss your daughter’s goals and how ISSH can help her thrive.

What’s the best way to decide if ISSH is the right fit?

Match mission, program, and culture. Review the school’s educational goals and consider your daughter’s interests, learning style, and aspirations. Ask about course pathways, co-curriculars, counseling, and support services. Speak with current families if possible. A strong fit feels like alignment: shared values, appropriate challenge, and a community where your daughter will be known and encouraged to lead.
