Learning to Love, Loving to Learn

High School Gr10-12

For over 50 years, Seisen has been educating independent young women to become leaders in their home countries and around the world.

Young women in grades 9-12 have the option of participating in a range of sports and activities. Older students have the option of joining in a summer service project abroad. They are offered a rigorous academic curriculum that includes optional IGCSE certificates and the International Baccalaureate Diploma. Seisen High School’s teachers are exceptional. They are highly skilled in their academic disciplines and deeply committed to the values of the school. They are also leaders within the international school community in Japan: their activities include serving as IB and IGCSE examiners, coaching girls in basketball summer camps in Afghanistan, building houses in developing countries, and offering workshops to other educators both locally and abroad.

Please take time to browse our website and contact us should you require further information – or better still – come visit us to see the future in our wonderful students.
