One of Japan’s three great riverside festivals. It is a majestic and brilliant riverside festival with a history dating back nearly 600 years. The boats decorated with the chochin lanterns that color the river during the Yoi Matsuri at night, and the Asa Matsuri in the morning where 10 young individuals swim in the river to offer cloth halberds to the shrine, are the main events of the festival.
It was one of 33 “mountain, halberd and stall events” in Japan to be registered as a UNESCO Intangible Cultural Heritage in December 2016, along with the Danjiribune event of the Owari Tsushima Tennoh Festival.
