Overview
Osenkaku is the only inn at Takaragawa Onsen, at the top of the Tone River system north of Minakami. Its four open-air baths sit along the river below the building, built from large boulders and filled from four wells without added water, heating or circulation; three are mixed, with bathing wear provided for women, and one is women-only. Rooms are in a 1955 cypress-wood main building, a 1936 wooden annex and a concrete east wing. Dinner features mountain dishes such as river fish and mushrooms, served in a restaurant or bamboo-screened dining booths; breakfast is a buffet. Free shuttles run from Jomo-Kogen and Minakami stations.
