Ubayu Onsen Masugataya

1 Osawa Ubayu, Yonezawa-shi, Yamagata-ken Ubayu Onsen Masugataya


Secret hot water! The mysterious spectacular outdoor bath is very popular!

Located in a deep valley at an altitude of 1,300m, you can enjoy milky colored springs in a wild environment surrounded by a precipitous cliff.

A wooden, 2-storey inn standing on a cliff featuring 13 rooms (all rooms with toilets and washlets), electricity is self-generated though mobile phones are usually out of service in the mountains.

Although it can be inconvenient, the euphoric impression of the stunning scenery attracts many secret fans!

The main fountain-sourced outdoor baths have 2 types: a mixed bath and a women’s only bath. The mixed bath allows guests to use towels to cover themselves while inside, so even women can enter without worry.

The cypress-made inner bath is different for men and women, but the number of washing stations and showers is few so it can get crowded. It is best to avoid crowded times!

If you go by car, you will have to take the mountain roads which can be very windy, so please be careful.
