Tsurunoyu's records go back to 1638, when the lords of the Akita domain used it as a bathing retreat. The inn keeps its thatched-roof honjin building and a riverside open-air bath whose water bubbles up from the gravel bed.

Why visit

It is one of Japan's most atmospheric surviving onsen: cloudy white sulphur water, wooden bath houses, snow-buried winters, and a mixed open-air bath fed directly from the source.
