Mutsu Yatate Onsen is located in Mutsu, Aomori prefecture, at the northern tip of Japan's main island. Its sulfurous thermal water emerges at around 42°C, recognizable by its characteristic smell. The bath house has an indoor pool, an outdoor rotenburo bath and a sauna.
Insider tip — Mutsu city is the gateway to the Shimokita Peninsula — Japan's northernmost and most remote mainland peninsula, shaped like an axe head jutting into the Tsugaru Strait. At its volcanic heart sits Osorezan (Mount Fear) — one of Japan's three great 'afterlife mountains,' where a caldera lake of vivid green and yellow sulfurous vents surround stone Buddha figures in one of Asia's most otherworldly sacred landscapes. Yatate Onsen draws from the same volcanic system as Osorezan's sulfurous springs — bathing in waters connected to Japan's most spiritually intense landscape.
