What Is a Private Onsen (Kashikiri)?

Kashikiri (貸切) means "for rent" or "reserved." A kashikiri bath is a private hot spring you book for a set period—typically 45–60 minutes—for you and your party. No strangers, no mixed-gender rules, and often no tattoo restrictions. Many ryokan also have rotenburo (outdoor) private baths with mountain or garden views.
