Getting this room

  1. Book it by name. Choose "Room with open-air onsen bath" (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 the view, where dinner is served, the beds.
  3. Check the confirmation. It should name the room with the bath. If it doesn't, contact the property.
