Shizuoka Prefecture／Central IzuAn Onsen Accommodation featuring a private open-air bath with free-flowing natural hot spring water

Facilities include a yukata selection service and complimentary computers. Various Room types are available to cater to a wide range of needs, from couples to groups, including barrier-free Rooms for a comfortable stay.
We stayed as a three-generation family trip.We have stayed here several times, and we are always grateful that you arrange a Room near the elevator for my husband, who has leg pain.My elderly parents were also happy to be able to use the private bath. Getting to the main building is convenient with the shuttle bus. Every dish at the renovated restaurant was delicious, and we especially enjoyed the ramen—both soy sauce and miso were very satisfying.The fugu hot pot was also great. The staff were kind and attentive, making it a wonderful trip.We look forward to visiting again.
Yahoo!トラベルユー... 2/15/2026This was my second stay, for one night on a weekday. The building itself isn’t luxurious, but with only a small number of rooms, it’s quiet and relaxing since you rarely run into other guests. Unless it was right after check-in, at least one of the private baths was usually available. The water temperature felt just right at first and gradually got hotter while soaking, so the 1-hour time limit didn’t feel too short—especially since I also wanted to try another bath. I was satisfied with both the variety and taste of the meals. Personally, I found the Chinese dishes a bit strongly seasoned and the desserts a little too sweet. The red miso soup at dinner was delicious. Everything was clean with no complaints, and they clearly put effort into the baths. At this price, I’m very satisfied with this Accommodation. It may feel underwhelming for those looking for something flashy or luxurious, but for me it felt like a very well-balanced Accommodation.
