"On arriving Japan back in 2007 we were warmly welcomed by Seisen and our four year old quickly settled into Bluebell kindergarten class. Since that time Seisen has been very much part of our daily lives not only from the aspect of providing a well rounded education to our three daughters but a strong sense of belonging.
Our whole family has found friendships within the Seisen community and we can rely on access to structured support from within the school to informal contact with teachers and other mums and dads in the area.
A strong and stable faculty, an excellent IB program and a diverse and fun social calendar all make us proud to be part of the Seisen family!"
Mary Chu, Seisen Former Students's Association President
“Every memory of Seisen is wonderful which includes the Sisters, my friends, teachers, staff, classes, participating in extracurricular activities, and being involved at school. What they all have in common is that as a child and student, I knew that I belonged at Seisen. As students, we always accepted each other even for our differences in culture, religion, and opinions. We didn’t judge and were never judged. I’m grateful to my parents for choosing Seisen for me since Seisen is a big part of who I am today."
Ms. Tontcheva, Kindergarten
"I am from Bulgaria and I have been teaching kindergarten since 1994.
I knew that I wanted to be a teacher at the age of fourteen. The reason I love teaching this age group is because everything begins in Kindergarten. This is a very special time in a person's life when the foundation for future learning is laid. It's really inspiring being in a Kindergarten classroom. Seeing the children's enthusiasm for life, innocence and curiosity about the world reassures me of a better, peaceful tomorrow. Coming from a small country I truly appreciate the opportunity to work in a vibrant international environment. I have learnt so much and grown both as a teacher and a person here at Seisen.
At Seisen every child is valued as an individual and is given opportunities to develop his/her unique strengths and talents, while being an important member of the community."

What does it mean to be a Seisen family?
My daughter Ayame has been a student at Seisen for over 12 years. She entered kindergarten and is now undertaking her IB studies in grade 11
We chose Seisen because of its academic reputation, and the ability to undertake the IB curriculum
Over the years we have seen our daughter grow and become a confident open-minded young lady. Through the dedicated and caring teachers and the open and flexible mantra of the school
We have also grown up with Ayame. Passionately following her participation is basketball Volleyball and many other activities. Meeting many of her friend’s parents and building strong and lasting relationship with them all.
The school has a wonderfully international and diverse population It actively empowers our daughters and encourages them to thrive in everything that they do.
We are passionate about Seisen and actively promote the school to all we meet.
