The hotel in Noboribetsu was very nice.  When we first arrived the staff was lined up to greet us.  The rooms were very spacious and nice.  I enjoyed the baths very much but the water was tooo hot.  Every 4 hours the bath area would switch from male to female. You must be very carefull and notice/read the noren before going into the changing room.  I could read the kanji character for man and woman.  I could also tell by the color of the noren.
