Yako Aru Teiji Seikoko no Monogatari.

Hino Mitsunari runs evening classes at a high school attended by foreigners, the elderly, and students struggling with various difficulties. The lessons are called “Community Ball” and involve everyone, including the teacher, sitting in a circle and thinking together on a question under the rule that no one should argue while someone is speaking. The various perspectives of the students all inform the film.
