Unique property in a quiet location but close to Upopoy Ainu Park and Museum. Awesome architectural features, especially for the outdoor osen facility. A relaxing break from busy tourist spots Sapporo north and Hakkodate south sides. NOT for families with young kids looking for city attractions or ones seeking night life but for couples for romantic getaway or seniors seeking an awesome, relaxing day/night. One of the BEST onsen experiences ever. Worth an overnight stay on way from Sapporo to Hakodate or reverse. Don't be stupid and carry your heavy luggage to here. Carry only day or two essentials and forward heavy luggage to your next stop from your previous hotel instead as transportation option is basically taxi or walk 20 minutes. I don't know why more people don't take advantage of this service.

The half board Japanese meals were one of the best we have had. The onsen was fabulous, especially the outdoor part. Though I should have been mindful that the one called O was opened to public during certain hours. It was a bit crowded during those times. All in all, a lovely stay !

Newer, gorgeous property with Ainu elements at a serene part of the small town. Nice, minimally designed room with great view of the lake, great for a relax trip. Onsen water is brownish and feels v therapeutic, smoothening for the skin. Food is alright, breakfast portion is a little small. Unlike other similar grade onsen hotels, there is no drinks provided in the room - only a jug of water, this is rather disappointing. Can't be sure the water is fresh. If this is due to environmental practice, the hotel could have provided water in aluminium can...

The area was beautiful and peaceful and very calming. The onsen felt realy nice and rejuvenating after our snowboarding crash course. They also had dryers in the hotels for snowboards and boots and where more than happy to turn it on for us.
