Inakayado Kawaguchi is a small country inn in the mountains of Ryujin village, Tanabe, Wakayama, and the home of a natural hot-spring bath called Gamanoyu. It calls itself a self-service inn with home cooking rather than special dishes. Before you book, three things matter: the six rooms are upstairs and the toilets are downstairs; the listed rates already include the bathing tax; and booking is by phone or a Japanese contact form, so details such as check-in time and cancellation are things to ask the inn.

Prices at Inakayado Kawaguchi
The inn raised its room, bathing and food prices from April 2026, citing rising costs. It lists two sets of rates, one for sightseeing and onsen trips and one for fishing and business stays, all including the 150-yen bathing tax:
| Plan | Sightseeing / onsen | Fishing / business |
|---|---|---|
| Dinner and breakfast | From 11,000 yen | 9,000 yen (packed lunch on request) |
| Breakfast only | 8,000 yen | 6,500 yen |
| Room only | 6,500 yen | 5,500 yen |
Which rate applies to me?
The page names the two groups but does not set out who qualifies, or say in so many words whether the figures are per person. Say why you are traveling when you ask for dates. Business guests on a longer stay can discuss the price, and the inn suggests the set meals from its dining room for anyone who wants a cheaper stay.
Is the bathing tax included?
Yes. The room page says the rates include the 150-yen bathing tax, so there is no separate onsen tax to pay on top. Our onsen bathing tax guide explains what the tax is.
The Gamanoyu hot-spring bath
When can overnight guests bathe?
Gamanoyu is the inn’s own indoor bath of natural hot-spring water. Guests can use it until 22:00, and if you ask, an early-morning bath is sometimes possible. The bathroom has body soap, shampoo and conditioner, and a hair dryer in the changing room, which can also be borrowed for your room.
What kind of water is it?
The official page lists it as an alkaline simple spring (alkaline, hypotonic, low temperature), and describes it as gentle on the skin. Among the conditions it lists the water for are nerve and muscle pain, joint pain and stiffness, bruises, sprains and poor circulation. It also lists when not to bathe, including acute illness with fever, serious heart disease and pregnancy, especially early and late.
Can I bathe with a tattoo?
The official pages do not mention tattoos, a private bath or an outdoor bath. Ask the inn before you book; our tattoo and onsen guide explains what to ask.
Can I visit just for the bath?
Yes, but the day-use bath opens on weekends and public holidays only: 13:00 to 20:00 on Saturdays and holidays, and 11:00 to 20:00 on Sundays. Adults (junior high school and up) pay 700 yen and children aged 3 and up 400 yen; residents of the former Ryujin and Miyama villages pay 600 and 300 yen, and holders of a disability certificate pay 300 yen. The inn says it may close or change hours, so call before you go.
What is the Gamanomizu machine?
Beside the entrance stand four vending machines selling the hot-spring water, called Gamanomizu, at 10 yen a liter, 24 hours a day, all year.
Rooms at Inakayado Kawaguchi
Where are the toilets?
All six Japanese rooms are on the second floor, and the toilets and washbasins are on the first floor; there are none upstairs, though there is also a toilet outside. Plan for the stairs at night.

Each room has a towel and toothbrush. Bath towels are at the second-floor counter, one per guest, and yukata are available on request. On the first floor are two massage chairs, free once for staying guests, and laundry is free for fishing and business guests. A vending machine stands at the front.
Meals at Inakayado Kawaguchi
What is served?
Meals are in the first-floor dining room. The inn says plainly that, as a country inn, it serves no special dishes: instead you get mountain vegetables, ayu (sweetfish) and home cooking. In spring that means itadori, zenmai, bracken, butterbur and bamboo shoots; in summer, wild ayu and amago trout from the Hidaka River and its tributary, the Samukawa. Cold hot-spring water, barley tea and tea are self-service in the dining room, with instant “hot spring coffee.”
Can the inn handle allergies or a special diet?
The official pages do not give meal times or say whether allergies or special diets can be handled. Ask when you book.
Children, cancellation and payment at Inakayado Kawaguchi
What do children cost?
The official pages give a child price for the day-use bath only (400 yen from age 3). Rates and rules for children staying the night are not stated; ask the inn.
What is the cancellation policy?
No cancellation rule appears on the official pages. Ask for it in writing when you book; our hotel cancellation guide covers what is common in Japan.
How do I pay?
Payment methods are not listed. Ask the inn whether it takes cards or only cash.
Getting to Inakayado Kawaguchi in Ryujin village
How do I find the inn?
