The traditional Japanese comedic form of rakugo has some pretty stiff physical requirements. Performers must use a fan and a small hand towel to help tell their stories; what they can’t use are their legs. Now that the 300-year-old form has made its way to English-speaking audiences, rakugo performers can finally joke that their comedy is “sit-down” instead of “standup.” But the difference between the form and, say, the oeuvre of Carlos Mencia doesn’t end with limited leg motion. Instead of milking laughs from topical one-liners, rakugo performers play every role in an extended situational comedy from the comfort of their floor pillow. English rakugo performer Kaishi Katsura is a master of translating the form for American audiences: He’s equally at home building a tale around the traditional characters of “geisha” and “ninja” as he is around “imprisoned dude in a tiger costume.” Sometimes, at the end, he falls down. The performance begins at 6:30 p.m. at the Japan Information and Culture Center, 1155 21st St. NW. Free. (202) 238-6949.
