Only the open-air bath is onsen (heated and with water added); the indoor bath in the same room is not.

Some room types are kakenagashi, others recirculated. Some plans serve meals in a private dining room instead.

Getting this room

  1. Book it by name. Choose "Room with onsen open-air bath" (温泉露天風呂付客室). Only some rooms have the bath.
  2. Ask what the website doesn't say. It doesn't mention free-flowing spring, the view, the beds.
  3. Check the confirmation. It should name the room with the bath. If it doesn't, contact the property.
