Esashi, in the Hiyama subprefecture on the Sea of Japan coast of southern Hokkaido, was one of the wealthiest fishing towns in nineteenth-century Hokkaido when the great herring boom transformed this coastal community into a prosperous port, its legacy preserved in the extraordinary collection of traditional herring merchant mansions (nishin goten) and the Esashi Oiwake folk song — one of Japan's most celebrated regional folk songs, sung in the distinctive pentatonic style of the Hokkaido coast. Esashi Onsen Hokkaido Extended draws on chloride-rich coastal thermal waters from the marine geological formations of the Hiyama Sea of Japan coast, offering warming maritime baths in a town of exceptional historical depth whose herring merchant mansion heritage, the Esashi Oiwake traditional music culture, and the coastal scenery of the Hokkaido outer Sea of Japan create a richly nostalgic and historically layered spa setting. The Esashi nishin goten herring merchant mansion preservation district, the Esashi Oiwake All Japan Folk Song Competition held annually in September, and the historic Esashi port and coastal road scenery of the traditional Hokkaido herring fishing culture make Esashi one of Hokkaido's most musically and historically distinctive coastal thermal spa destinations.
