Kurokawa Onsen Yū Irodori Bekkan

A small hotel, acquired by Yukyonohibiki Yusai. At check-in they give you a ticket to use the baths at the main hotel (across the street, 2 minutes on foot). Rooms are in classic style — some with tatami, some with beds. The hotel itself has 2 baths (men's and women's, no rotation). Photos from Google. The men's bath temperature at the time of visit was 45-46, with a posted sign asking people to stir the water to cool it down. Outside near the entrance there's a large foot bath.
