Sodaturukai's Origin

old The Sodaterukai was established in 1968 by teachers, parents and education-experienced people.

At the time, Japan's economy was soaring and the materialistic development of the country could be felt with every passing day. However, the environment in which kids were raised also went through a tremendous upheaval, which brought several problems to the surface in the children's education.

It was through this tumultuous period that the Sodaterukai came up with ideas to preserve the ideas such as "True knowledge can be obtained through direct experience" and "For kids to learn the true independence through various nature experiences and everyday life experience is needed." Unfortunately, these ideas were being washed away by this fast-changing era.

Sodaterukai's Ideology

Every child has his or her own potential. That is why they should have the opportunity to ignite the potential and grow it on their own. This is the Sodaterukai's ideology.

Sodaterukai's Instruction Policy

instructor The Sodaterukai seeks to dig out the potential out of each kid while letting them think, act and learn on their own.

Upon meeting a challenge, kids need to learn how to think, draw a conclusion and act on their own. Instructors should be there only for supervision and to offer advices.
