The Nagahama Hikiyama Festival takes place at Lake Biwa, Shiga Prefecture in April each year. It is one of the Three Great Float Festivals in Japan and designated as a national important intangible folk cultural property. On December 1, 2016, UNESCO registered thirty-two Yama, Hoko, and Yatai float festivals in Japan, including the Nagahama Hikiyama Festival, in its list of Intangible Cultural Heritages.
The festival is said to have begun over 400 years ago during the Azuchi-Momoyama period (1568–1600) when Toyotomi Hideyoshi—one of the most celebrated warlords in Japan—gave gold to the townspeople to celebrate the birth of his first son. The townspeople used the gold to build floats.
