A hot spring flowing along the road to the UNESCO World Heritage Nachi Falls. Ease your travel fatigue and refresh yourself completely.
Play the role of "yumori" (bath keeper) and fill the tub yourself to your preferred temperature. The spacious tub comfortably fits three adults with room to spare. Since you have the whole house to yourselves, you can soak any time, 24 hours a day, once the water is drawn.

Bedroom, manga corner, and dining area come together in one spacious, relaxing interior. After a full renovation in April 2026, up to 4 guests can stay comfortably.
The king-size bed (180cm wide) offers plenty of room for couples or solo travelers. A dimmable bedside light sets the mood in the evening.
Climb the ladder to the tatami loft, a cozy space to relax for parties of two. For 3–4 guests, or if two guests prefer separate beds, a queen-size mattress (160cm wide) is provided.
Perfect for meals, or for spreading out a manga after your bath. Compact, but seats up to 4.
Unwind after your bath with unlimited reading from our library of 300 English manga (plus 1,000 more in Japanese). Losing yourself in a story while lounging around is a luxury unique to this stay.
Everything you need for simple, comfortable living is here — perfect for both short stays and longer therapeutic onsen retreats ("toji").
A key box lets you check in anytime, day or night — no staff required. Check-in instructions will be sent after your reservation is confirmed. Check-in from 3:00 PM, check-out by 12:00 PM.
A compact but full kitchen with a refrigerator, microwave, toaster, and rice cooker. Cookware, dishes, and basic seasonings are also provided.
The changing room, renovated in June 2026, includes a washer-dryer — ideal for longer stays.
The entire building is step-free. The bathroom is wheelchair-accessible and fitted with handrails.
Nachi Falls, the Kumano Kodo trail, Katsuura's tuna, the onsen, and manga — to enjoy it all, we recommend staying two nights or more.
These are actual reviews posted on Airbnb and Booking.com, shown exactly as written.
We recommend arriving by car. There are few restaurants within walking distance, which can make dining and shopping inconvenient. By car, many restaurants are within 10 minutes, and it's also convenient for exploring the area.
Yakisugi is a traditional Japanese technique in which the surface of cedar boards is charred, making the wood more resistant to weather and pests and giving it a distinctive black texture. We charred and installed every board ourselves, using cedar grown locally here in Kumano.
In a June 2026 renovation, most of the walls were finished with "shikkui," a natural lime plaster. Shikkui absorbs and releases moisture to help regulate humidity, and has long been used in traditional Japanese storehouses and castles.
That's why the bedroom has soundproof inner windows and a soundproof door. Since installing them, we've had zero reviews mentioning noise. For anyone still concerned, earplugs are also available.
We don't provide single-use plastic amenities like toothbrushes. Our soap is chosen for high biodegradability, and our shampoo and conditioner are selected with both hair and scalp care in mind.
