This hotel-resort is well loved by young Japanese families. For a tourist passing through Uno area it is 20 minutes from Uno by bus or taxi. The hotel sits alone in this area with a beautiful beach. Staff is very helpful

last minute booking… what a surprise! Beautiful hotel and location, excellent service. Some of the hotel is a bit dated but was nostalgic for me. Kinda like Hawaii 5-0 old series feel. The view was incredible!!!! Will be back when the wisteria is in bloom across the street as well as to enjoy the beach!

fabulous location, helpful staff but hotel itself needs a good refurbishment, carpets dirty and smelly, paintwork worn. Other floors of the hotel might be better but the foor I was on was way overdue for a spring clean.

They advertised having several restaurants one of which was the buffet which they charge over ¥5,000 for and they weren't even serving anything other than dessert and one type of meat even though they advertised it as having many different types of food. Only one of the other restaurants was open and there is only one other restaurant in town that serves dinner. The rugs and sheets and everything were stained and the hallway rugs looked like they hadn't been cleaned since installation 30 years ago. The onsen and service was good but did not make up for the false advertising of everything else.
