Niihama Taiko Festival in Niihama
Niihama Taiko Festival, held each autumn in Ehime Prefecture, traces to Heian or Kamakura-period harvest rites and centers on taikodai, five-meter gold floats carried by up to 150 men each around a massive drum. Historically a kenka matsuri, or fight festival, involving float collisions, it phased out formal clashes roughly twelve years ago, though its high-energy atmosphere still occasionally produces friction.
The Niihama Taiko Festival is believed to trace its roots to the Heian or Kamakura periods, emerging originally as a harvest celebration in which communities gave thanks to local deities for agricultural bounty, a devotional function that has since layered over centuries into something considerably more physical and competitive.
