Leaf-Colored Treasure Box

This collection brings together thirteen tales drawn from real life. The opening story centers on Yoshihiro, a sixth grader at Nakasu Elementary School in Moriyama, who has been asked to learn a story by heart and recite it before his classmates. A visit from Ichiryusai Teisui, a storyteller recognized as a human cultural asset, is also on the school's calendar.

On the morning of his speech, Yoshihiro finds himself unable to say a word in front of a large audience. The summary ends at this point, so the rest of his story and the other twelve tales are not described.
