All rooms feature private baths with free-flowing natural hot spring water. Enjoy a relaxing escape from the hustle and bustle of everyday life.

The Okuyamaga Onsen Ryokan, established during the Showa era, retains the nostalgic atmosphere of that time. While Hirayama Onsen is known for its mild temperatures, at Okuyamaga Onsen Ryokan, you can enjoy onsen with a spring temperature of 60 degrees. The onsen water flows directly from the source to the large communal bath and all guest rooms, and you can bathe at any time in the private baths of your room.
