The environment is excellent! Bathing in open-air hot spring while snowing is enjoyable. The room is spacious and with beautiful view. However, the electricity wiring inside the room needed to be improved. When we tried to boil water, the fuse blew. The heater in the room shut down. It's 11 o'clock at night and there's no staff in the reception desk. We could not find any phone no. for emergency contact as well. Fortunately, there's air-conditioning in the room and it could bearly keep the room warm in the sub-zero temperature. When we told the staff about no heater last night, the staff told us "OK" and do nothing, like he didn't care at all. We were a bit disappointed as Japanese is well known for their service, perhaps not this hotel.
