About Seisen International School

Seisen International School is a girls-only, Catholic school situated in the ward of Setagaya in Tokyo, Japan. It is an English language private school that is a member of Handmaids Schools, an organisation which has a large number of different schools all around the world, in five continents across the globe, from the UK and Europe all the way to South America and Africa.

Seisen began as a Kindergarten in 1962 operated by the Handmaids of the Sacred Heart of Jesus before expanding up to third grade by 1964. By the time it had moved to yoga in 1972, it was ready to expand so that it catered for students from kindergarten up to grade 12 as it does today. It became Japan’s third school to authorise IB Diplomas in 1986, which expanded into the ability to offer the IB Primary Years programme in 2007. The current head has been serving since 2015.

Values and Vision

Seisen focuses on providing an international education to students in order to prepare “today’s students for tomorrow’s world”. Using its school motto of “learning to love, loving to learn”, it is a school that promotes a positive attitude to learning through its high expectations as well as support for students. As an all-girls school, it believes this is a format that is ideal for letting its students know that there is no limit to their achievements.

Strongly influenced by its Catholic faith, the school has regular services in its very own Seisen Chapel, including masses every Sunday and First Friday as well as for events in the Catholic calendar.
