A grand rock bath of overwhelming scale, seasonal charm, and an all-you-can-drink dinner.

The property at Oyu Onsen, with a history of 1300 years since its opening, boasts a large rock bath with water flowing directly from the source. There is also an open-air bath where you can feel the four seasons of Uonuma. From the main building and riverside, you can view Echigo Komagatake, one of the Echigo Sanzan mountains, and the clear stream of the Sarugawa River. Alcohol and soft drinks are all-you-can-drink during dinner. Additionally, there are private karaoke rooms and indoor recreational facilities such as table tennis, which are available for free.

  • The Facilities and meals are standard for an Itoen Group Hotel and are by no means luxurious, but the value for money is excellent. More than that, the staff were cheerful and very courteous, which made our stay truly pleasant. Thank you very much.
