Thank you for picking us up at the station—it was very helpful. The seafood dinner and kamameshi were incredibly delicious, and we ate a lot! The bath was wonderful, and the Room was spacious and very comfortable. The front desk staff were also kind and helpful.
Yahoo!トラベルユー... 7/10/2026The Facility is old, but I think they do a great job keeping prices low. It’s hard to call it outstanding, but it offers good value for the Accommodation Fee. The selection isn’t large, but we were satisfied with the sashimi, grilled seafood, and sushi. The sake we ordered additionally was delicious. We also loved that the Onsen water temperature was just right. We’d like to stay again if we have the chance.
