Highlights
UtaseyuAbout
Masa-no-hinoki-yu is a single open-air bath at Yuki Onsen, booked by one private party at a time, up to six people. The tub is hinoki cypress, and the water runs straight from the source without recirculating. A 2022 renovation added a second tub of unheated source water next to a hot waterfall spout, for hot-cold contrast bathing. Bathers describe the water as soft on the skin and the cypress scent as relaxing, with a river running just below the bath. The bath had stood closed for nineteen years until community donations and support brought it back, with Hiroshima-born entertainers cutting the cypress for the tub themselves. There is no lodging here: guests collect the key at a reception building a short drive away before heading over to bathe in private.
