International School of the Sacred Heart (ISSH or Sacred Heart), is an all-girls K-12 school located in Hiroo. It is one of a global network of schools and colleges under the direction of the religious order of the Sacred Heart, and incorporates Catholic value principles into its curriculums and character development frameworks. Established in 1908, ISSH has sustained its goal to provide an education for girls and young women to prepare them for success in an ever-changing world for over a century. With a network of nearly 5,000 alumni worldwide as well as the alumni networks of sister schools both internationally and domestically, Sacred Heart students and alumni maintain a well-connected sense of community long after graduation.
Sacred Heart is a small school, with a graduating class size of around 50 pupils. The school maintains a typical US-based progression, offering AP classes in High School. Its in-house curriculum combines elements of US, UK, Canada, and Australian curricula, and all aspects of teaching and learning are tailored to girls, designed purposely to develop their confidence and potential, and empower them to pursue whichever direction their talents lead them. Due to the small class size, each student develops a meaningful rapport with teachers and classmates, and is able to feel supported and valued within the school community. The school is also religiously diverse, with students who identify with more than 15 unique religions, denominations, or belief systems, as well as those who do not identify with any religion.
Sacred Heart is dedicated to serving the educational needs of the daughters of foreign nationals in the Tokyo area. The school offers programs for Pre-K (ages 3-4), Kindergarten (age 5) and Grades 1-12. Boys aged 3-5 years are accepted into the Pre-K and Kindergarten programs. The school community is predominantly made up of internationally mobile families for whom the Japanese education system is not an option. The school accepts students transferring from accredited International Schools in Tokyo on a case by case basis. At least one of the parents must be able to speak and read English.
The application process consists of an online application, followed by a screening or assessment and then an interview. The admissions committee considers factors such as language, educational ability and background as part of the admissions process to ensure diversity and balance throughout the student body.
The all-English curriculum at Sacred Heart brings together a mixture of different educational philosophies. Fundamentally following the standard US progression, the curriculum builds to AP classes and exams as the focal point for the last two years. However, curricula from other English-speaking countries worldwide, as well as elements of the IB system are also incorporated with ToK, or Theory of Knowledge, being a required class for graduation.
Sacred Heart’s coeducational kindergarten offers a play-based curriculum for children between ages 3 and 5. Students build foundational skills in numeracy and English literacy, and have time each day to play together in the multiage Open Area with children from other classes. Students in the all-girls Junior School take English language arts and mathematics, and all students in Kindergarten and Junior School learn social studies and science through the International Primary Curriculum, which centers learning around a themed unit with a heavy focus on interdisciplinary and real-world learning. All students learn Japanese from K3 through Grade 2, and then starting from Grade 3, they can select Japanese or French for their second language. They take art, music, physical education, and have a lesson in the library weekly with specialist teachers.
Middle School students at ISSH take English, mathematics, social studies, science, and foreign language as their core subjects. Each student also takes both 2D and 3D art, drama, and music, as well as PE and food technology. Students in both middle and high school have the opportunity to take Options courses, a program which allows students to take elective courses in subject areas they might not normally have access to, or that allow them to further develop an area of interest. Some examples of Options courses include musical theater, photography, filmmaking, robotics, AI foundations, programming in Java, and journalism.
In the High School, ISSH offers 22 AP courses, which is comparable to schools with a much larger student body. It is well-covered across STEM, offering AP Biology, AP Chemistry, AP Physics, AP Computer Science A, AP Calculus AB and BC, and AP Statistics. All three AP visual art courses are offered, as is AP Music Theory. The school offers both AP English courses, AP Japanese, and AP French, and a range of social studies and history courses including both AP Micro and Macroeconomics, AP World History, and AP European History. When a student wishes to study for an AP exam not offered as a part of Sacred Heart’s course listings, they are able to take it as an independent study. Sacred Heart offers both AP Research and AP Seminar as a part of the AP Capstone Diploma program.
In order to ensure students are able to schedule the AP courses that best fit their goals and university aspirations, each ISSH student receives individualized counseling to ensure student success. They first attend a session in Grade 10 about Grade 11 and 12 course choices with HS leadership and the college counselor, and then, following the session, are given the opportunity to take part in course selection consultations with current Seniors, who are able to give first-hand advice regarding the scheduling process, as well as current AP faculty. Like many smaller schools, Sacred Heart offers each course a limited number of periods per semester, so the school ensures that students are prepared and informed to make the course selection choices best suited to their needs. A small handful of AP courses at ISSH require a prerequisite course and therefore must be taken in senior year, but all others can be taken prior to Grade 12. For enrollments into Grades 10 and 11, HS leadership consults with the family during the admissions process to ensure a good fit.
Sacred Heart takes a holistic approach to opportunity and character development, offering students a range of activities in sports, the arts, volunteering and leadership. In addition, the school offers a number of extracurriculars in cooperation with St. Mary’s International School and Seisen International School to allow for co-ed activities, such as the annual musical.
Sacred Heart maintains a robust Student Council, with elected 30 leadership positions available each year. An executive council presides over five individual councils pertaining to different areas of student life: the Academic Council, the Fine Arts Council, the Sports Council, the Social Service Council, and the World Council. There are also three elected representative positions at each grade level, allowing students to get involved with leadership from Grade 9.
ISSH is a member of the Kanto Plain Association of Secondary Schools (KPASS) league and offers 6 competitive teams across the three athletic seasons. The school strives to ensure that all players have a chance to participate in matches regardless of experience and ability level, offering both an A and B team in middle school and both a JV and Varsity team in high school for each sport. A number of athletic clubs outside of the KPASS league are available as well, depending on student interest. Some recent examples include fencing and Japanese ekiden.
Arts extracurriculars are offered through KPASS and independently, and the music program is particularly strong. Choir is particularly popular, with 70–80 students in each of the school’s three choirs. Many students are involved in orchestra or the rock band, a unique extracurricular that records its own music and music video each year. ISSH hosts the KPASS event Artscape each year for visual arts, and participates in the KPASS drama festival. The school’s dance club is very popular and performs at school events.
ISSH also participates in Model United Nations, Debate, Brain Bowl, Math Field Day, and Speech Contest. The school’s VEX robotics team participates in competitions against both local and international opponents, and has received a variety of awards and trophies since its inception.
Social awareness organizations are also widely popular at ISSH. The school has partnered with the US 501(c)(3) nonprofit organization Nepal SEEDS for more than a decade, working together with two local schools to create lasting solutions to improve and sustain the quality of the schools, water, health, and environment. Students who participate in the program have the opportunity to travel to Nepal and visit the schools that ISSH partners with. Other popular social awareness and service groups include Amnesty International, a human rights advocacy group; TASSEL, a group dedicated to helping alleviate poverty in rural Cambodia by teaching high-quality English to underprivileged children, and the GSA, the school’s student-run LGBTQ+ advocacy group.
Sacred Heart maintains a system for establishing interest groups that allows any student interested in leadership to create her own club. Students can pitch new club ideas each year to a panel of faculty and Student Council executive council members, and, if the pitch is successful and they meet the minimum membership and sponsorship requirements, can then establish clubs which they may lead for the rest of the school year and in subsequent years if they wish.
In 2024, approximately 100 pupils at the school sat AP® exams with a total of approx. 300 exams administered. Sacred Heart reports that 100% of AP® students received scores of 3+. The percentage of AP® students receiving scores of 4+ or 5 was not reported on their website.
