“As an international school graduate and father of two boys , I have gotten to know Seisen and its environment from many angles throughout the years. I share many precious memories with Seisen graduates and have been blessed to get to know the faculty and staff after enrolling both my sons in Seisen kindergarten. My wife and I wanted my eldest son to experience a Montessori education before St.Mary’s and my youngest son is currently following in his footsteps. I was delighted to see both my sons enjoy and learn so much in Seisen’s unique environment and am grateful to share this special experience with them. Seisen’s education system had always impressed me as a student, and now as a father, I feel the curriculum has kept evolving and enhancing year after year. Needless to say, I have utmost faith in Seisen’s highly trained and experienced teachers who continue to provide a priceless education to all. 

We love Seisen and are proud to be a part of the greater Seisen family!”

“What does it mean to be a Seisen family? 

To me, it's an opportunity to be a part of an international community here in Japan of families that want the best possible futures for their daughters. 

The school community provides a nurturing environment where our daughter can grow and develop. She knows that while she always has a helping hand when she needs it, that she is empowered to step out of her comfort zone and to 'find her voice'. The school recognises and understands that every girl is unique and provides them with the support and guidance, as and when they need it. 

The school community provides a strong stable base helping our daughter to be globally minded in a complex and ever-changing world. We see this coming through, both via the education provided by the school but also the diverse international student population that she sees in class every day. This gives us confidence as parents, that our daughter will be able to navigate whatever challenges she finds in the future. 

Maybe most importantly, we have had the opportunity to meet some amazing families here in Tokyo and we look forward to remaining friends for many years to come as our daughters grow up together.”
