Komoro Grand Castle Hotel
Nagano Prefecture／KomoroEnjoy dining at a city Hotel, perfect as a base for sightseeing.
A city Hotel with natural Onsen, conveniently located just a 1-minute walk from Komoro Castle Ruins Kaikoen and a 5-minute walk from Komoro Station. It caters to a wide range of needs from sightseeing to business use, and also offers conference rooms and banquet halls. We recommend the high-floor rooms on the 7th floor and above, where you can enjoy a view of the historic townscape.
Three elderly women stayed here together. We arrived by car, and the location was easy to find. The underground parking garage was spacious, so we could park with peace of mind. Kaikoen Garden is right next door, and the view was wonderful. The bath also had a great view, with large windows that made it easy to relax. We always stay at Itoen Hotel properties. The all-you-can-eat and all-you-can-drink options are affordable and very appreciated for seniors. The front desk staff were also friendly, and we enjoyed chatting at checkout, which made it a great trip. Thank you very much.
Yahoo!トラベルユー... 7/30/2026Itoen Hotels are reliably consistent as always. Affordable, with buffet-style breakfast and dinner, plus all-you-can-drink in the evening. With seasonal fairs, there’s always something new to enjoy, making you want to come back again and again. What’s especially great here is how spacious the dining venue is. Even with a large number of guests, it never feels crowded. The baths are Onsen as well, truly relaxing. I’ll be back again, and I look forward to staying with you then.
