The Japanese tradition of rakugo (comedic storytelling) depends largely on a quick wit and a way with words. So when storyteller Hayashiya Kanpei became speech-impaired due to a stroke, the challenge he faced getting back on stage was a momentous one.

Kanpei, 67, and his struggles are the subject of a new documentary film titled "Namida no Kazu dake Warao Yo" ("Let's Laugh As Many Times As We Cry").

The artist was 41 when he suffered a brain hemorrhage. It left him paralyzed on the right side of his body, which also affected his speech. Popular for his brisk way of speaking and specializing in classic rakugo stories, Kanpei had been promoted only five years earlier to the status of master storyteller or shin-uchi.
