This onsen is a small traditional Japanese inn. We were there for 3 days, and loved it! The food was incredible, and the rooms are beautiful. Our room had a private outside tub, and the inn had two different outside bathing areas that you could reserve. Overall, the most relaxing, enjoyable three days.
The area had a fun fish market to visit, and is easy travel distance to the Satta Pass, a hike with a view of Mt. Fuji.
