The purpose of this study is to create 'ESD Community of Practice' through the 'ESD training experience' in school and to narrate the 'experience' and the 'story' of the teachers who are teaching ESD classes in school. The teachers found out that ESD includes various school subjects through the ESD teaching training. Through the training for teachers, the ESD Community of Practice was formed and the members of the community began to communicate each other about ESD in natural order. Moreover, the training experience made the members bond by forming a common ground. The Community of Practice was being vigorously active as the place to exchange of opinions to achieve ESD, linked to diverse school subjects. The teachers could verify that the students learned the importance of educational environment -not only from the ESD class room teachings but also in general - and in overall, the teachers also could confirm that the students got mature very much. Over the study, we learned that the Community of Practice can vigorously active and can be such influential. We also realized that an individual can have various learning and experiences from participating in the community.
