Naburi, an area in Ogatsu town, Miyagi, which was struck heavily by the tsunami of 2011, has a traditional fire-warding festival that takes place on January 24th. An improv show utilizing explicitly sexual, bawdy humor with phallic and yonic props is held during the event. This year (2013) was the second time the event was held following the East Japan Earthquake.
