Wake up a little early tomorrow and try the other!

We have two open-air baths with different atmospheres.
Listen to the beautiful music of seasonal nature surrounded by tranquility.

Shinyasunami Onsen, the source spring, is known for its gentle water.
Each bath alternates between men and women every morning and evening, so you can enjoy both in different atmospheres.
