In this session we have Mr. Katsura Shuncho the Thid, the master of rakugo storyteller, to share the image how the indistinct correlations such as the class consciousness and the master-disciple relationships in the world of rakugo have had impact on the storytellers performance. Likewise, we will consider about the effectiveness of the laughter in the sport coaching environments. There are some possibilities that the laughter created by both coach and athletes will bring the favorable atmosphere and make the more desirable relationships between them. In that case, such connection will provide the athletes the environments which will enable them to learn proactively and to boost up the performance.
