Liked: Cleanliness, staff & service, amenities, property conditions & facilities
We stayed in rm 106 it was awesome it had a sauna, private outdoor Onsen, with hot spring water and a wooden soaker tub. Tatoos allowed in the public Nonsense. If you get a smaller room they have 2 private Onsens that can be reserved. Traditional Japanese Breakfast was great. We will stay again.
