Maybe you love the idea of Japanese hot springs but aren’t quite ready to go “completely naked” with strangers. Maybe you have tattoos and are worried about entry rules. Or perhaps you just want a quiet, intimate moment with your partner or family.
Whatever your reason, a private onsen is the perfect solution. In Beppu, we call these Kashikiri-buro (reserved baths) or Kazoku-buro (family baths), and they are the secret to a stress-free, luxurious experience without the high price tag.
What is a Private Onsen?
Unlike public baths where you share the water with others, a private onsen is a room reserved for a set amount of time (usually 50–60 minutes). You get your own changing area, washing area, and a beautiful hot spring tub all to yourself.While many people think you have to stay at an expensive ryokan (traditional inn) to get this privacy, Beppu is famous for offering “day-use” private baths. You can simply show up, pay a small fee, and enjoy world-class volcanic waters in total seclusion.
Why Beppu is the Best Place for a Private Onsen Experience
Located on the coast of Kyushu, Beppu produces more hot spring water than anywhere else in Japan. This abundance means the variety of private onsen in Beppu is staggering. You can choose from:
- Milky-blue sulfur waters in the mountains.
- Modern, chic rooms near the city center.
- Classic wooden tubs with forest views.
Best of all, many facilities use a system where the tub is completely drained and refilled with fresh hot spring water the moment you insert your coin or key!

Practical Tips: Prices, Booking, and Etiquette
How much does a private onsen cost?
In 2026, prices generally range from 2,000 to 4,000 yen per hour per room. Since these rooms usually accommodate 2 to 4 people, they offer incredible value compared to spa prices at Western hotels.
How to book your session
- Walk-ins: Most standalone “family bath” facilities operate on a first-come, first-served basis. You might have to wait 15–30 minutes on weekends.
- Phone/Online: Some larger facilities and hotel-based onsen allow reservations.
- The “Monitor” System: Many Beppu spots have a screen at the entrance showing pictures of each room. If the light is green, the room is available!
