Iizuka Yamakasa, a summer festival cherished by the citizens, is said to have started during the Kyoho era and has a history of more than 40 years since its revival. On the day of the "Oi-yama" finale, about 3,000 men dress in traditional water happi coats. The sight of them dashing through the streets, soaked with water splashed by spectators along the roadside, brings excitement and a momentary refreshment to the city of Iizuka!
