The Akishima Citizen Whale Festival will take place on the first weekend at the Showa Park (athletics stadium). The nearest station is the Higashi-Nakagami Station on JR Ome Line. Hihglights include a giant whale being pushed through the streets and a fireworks display which usually takes place on the Saturday night. While you may be questioning the audacity of Japan in holding a fesival celebrating whales, this event is held to commemorate the discovery of an ancient whale fossil found in the town in 1961.
