Ondonoseto is a sake brand from KK Fujioka Shuzouten, a brewery whose name ties the label to the Ondo-no-seto strait on the Seto Inland Sea near Kure, Hiroshima, a waterway with strong regional cultural identity. The strait is historically notable as the site of a legendary feat attributed to the 12th-century military leader Taira no Kiyomori and remains a defining geographic landmark of this coastal corner of Hiroshima Prefecture. The brand carries that regional maritime character, connecting its sake to the landscape and heritage of the Seto Inland Sea.
