The oldest record of a float festival held at Shioya Ko Shrine is from Bunkyu 2 (1862), in Shibahara family documents that mention floats. The float festival tradition was passed down among hamaotoko, or male salt farm workers, starting in the late Edo period. Now, in addition to the large floats representing the eastern and western districts, floats such as those for children have been added to the festival. It is a traditional event including both elegance and bravery; at the shrine, “Ise Ondo” (a traditional folk song performed by musicians, singers, and dancers) is performed, and brave men alternate between pulling a float and hoisting it above their heads. Of all the float festivals that occur in the city, this is the only one where one can see large floats being hoisted. This festival represents the unique culture of a region where people make their livelihoods from salt production, and it was designated as an Intangible Cultural Property of Ako City in Heisei 28 (2016).
