Renovated Japanese-style Business Hotel with Onsen large bath and free Wi-Fi.

The Property, which reopened in June 2020, is a simple and affordable Japanese-style Business Hotel, complete with an Onsen large bath. Conveniently located for sightseeing, it also offers free parking for up to 100 vehicles. The new Business wing features 20 single rooms, each equipped with a semi-double bed and clean, stylish flooring. Facilities include free Wi-Fi, a 32-inch TV, and individual air conditioning. Additionally, guests can enjoy the beautifying effects of the Onsen and dishes made with locally sourced Yamagata rice.

  • This was my first time staying here.I was able to stay at a very reasonable rate.The staff were also very helpful.The Room felt simple.It would have been nice if there had been an air purifier or a humidifier.The lobby and other areas were spacious and relaxing.There were three baths, but I was a bit disappointed with the open-air bath in the basement, as the view was just stacked stones and it felt like it had been forced into an open-air style by removing a wall.

  • Although it was a single Room, it felt very spacious. There were three baths, and the open-air bath was especially relaxing! Above all, the breakfast miso soup was hearty with lots of ingredients—warm and homey—and it alone made the rice go down easily. This Accommodation truly made me feel glad to be Japanese.
