International Baccalaureate

 Seisen International School has been an International Baccalaureate school since 1986.

We were the third school in Japan to offer the IB  Diploma Programme. The programme has continued to grow over the last 35 years. Critical thinking, community service, and an exposure to a wide variety of intellectual viewpoints reflect what both Seisen and the IB value.

In 2007 the Elementary School became authorised to offer the IB Primary Years Programme (PYP). The PYP is a curriculum framework for international education. The programme focuses on the holistic development of the child addressing the physical, social, emotional, cultural and academic well-being of each student and reflects our strong belief that education must address the development of the whole child. Seisen is one of just two schools in the Asia Pacific region blending the elements of Montessori and the PYP.

In July of 2020 Seisen became authorized to offer the IB Middle Years Programme.

As of July 2020 Seisen International School is authorized to offer the PYP, MYP and DP, making us the first All-Girls IB Continuum school in Japan.

Student-Teacher Profile at Seisen


We are all leaders. We are positive role models for each other. We recognize and utilize the many talents in our learning community. As leaders we understand the importance of intellectual, physical and emotional balance to achieve personal wellbeing for ourselves and others.


We represent many cultures, and are all open to and respectful of the perspectives, values and beliefs of others. We are eager to expand our awareness and understanding of the world and the global dimensions of situations and subjects. We are developing as global citizens, motivated to participate in and equipped to live in an ever-changing world. We are committed to making a difference, just as St. Raphaela did in her day. We are interactive members of a global network of Handmaids of the Sacred Heart of Jesus schools.


For Seisen International School, God comes first - His loving presence and action pervades the school and calls each one to live as value-based, ethical women and men. We reverence the spiritual treasures of the Catholic faith and other faiths and enter into dialogue with them. We encourage each other to develop our own religious beliefs.
