Baths for ¥300 or less

Locals' everyday baths. Bring soap and a towel; keep it quiet and short.

42 Facilities

¥300 or less — the price of two canned coffees — still gets you into a genuine free-flowing hot spring in parts of Japan. Almost all are communal baths run for local residents, not tourist facilities.

This list gathers those baths. Bring soap and a towel, rinse before entering, don't hog the washing stations, don't linger chatting in the changing room. You are a guest in someone's daily routine — be quiet and be brief.

O-yu (Nozawa outer bath)

The centerpiece of Nozawa's 13 public baths, a traditional bathhouse in the middle of the village. Local 'yunakama' associations have cleaned it daily since the Edo period; payment is a donation in the box at the door. Two pools, hot and 'mild' — though even the mild one exceeds 42°C. Adding cold water is bad manners: rinse first, then keep soaks short. No soap or shampoo.

Maga Onsenkan (Yubara Onsen area)

The communal bath of Maga Onsen, a tiny hamlet of stone stairways on a slope above a tributary of the Asahi River in the Yubara Onsen area. Legend says a defeated warrior healed his wounds here some 700 years ago. The star is the 'Makuyu', a mixed rock bath of about 1.6 × 2 m and 1.2 m deep, so you soak standing up — often called Japan's smallest mixed bath — with lukewarm 39°C water bubbling up through cracks in the rock floor. The men's and women's baths connect to it and cost ¥250; the Makuyu is ¥400 (max 8 people, one hour) and a private bath ¥1,300 for up to three. Open 08:00–21:00 (last entry 20:10), closed Tuesdays (open on holidays). No towels allowed in the mixed bath, so be prepared. About 20 minutes by car from Chūgoku-Katsuyama Station.

Halfway along Ideyu-zaka, the steam-wreathed main street of Beppu's Kannawa district, this communal bath is run by the local residents' association. In typical Beppu style the changing area and bath share one room, and hot sodium-chloride water rich in metasilicic acid flows freely. Visitors pay only ¥100 — technically a coin-locker fee rather than admission. Open 06:30–21:00 daily. No soap or shampoo and minimal washing space, so follow local manners: quiet and quick. There is a toilet on the little square out front, and the Jigoku-mushi steam-cooking workshop and Umi-jigoku are two minutes away, making it an easy stop on a Kannawa stroll.

Known as a 'triple beauty bath' for combining sulphur, bicarbonate and sulphate, it faces the flanks of Myōkō. Free of charge from sunrise to sunset, open April to November (closed in winter; boots needed while snow lingers); no bathing on Monday and Friday mornings for cleaning. Fifteen minutes further along the gorge is the mixed 'Kawara-no-yu' (Jul–Nov). No soap allowed and minimal changing space, so follow local etiquette.

Tsuetate Onsen Moto-yu communal bath

Tsuetate Onsen, where inns line both banks of the Tsuetate River on the Kumamoto–Ōita border, claims 1,800 years of history as the bath water of the infant Emperor Ōjin. Moto-yu is the communal bath said to be its origin: a single half-open tub carved into the rock face beside the riverside promenade — mixed, free and open 24 hours, nothing more. The sodium-chloride water, cooled from a 98°C source, leaves the skin soft. Changing space is basic and screening minimal, so many people wear bathing garments or a wrapped towel; early morning or night is the best time. Combine it with a wander through the 'sedoya' back alleys and, in May–June, the 3,500 carp streamers strung across the river. About 50 minutes by bus from Hita Station.

Amagase Onsen Yakushi-yu open-air communal bath

Amagase Onsen, where steam rises along the Kusu River in Hita, Ōita, is counted with Beppu and Yufuin among the 'three great springs of Bungo'. Its trademark is the communal open-air baths dotted along the riverbed, and Yakushi-yu is one of the most approachable: a single rock tub, mixed bathing, ¥100 dropped into an unattended box. The 75°C simple sulphur spring is diluted to a comfortable temperature, with a faint whiff of sulphur and a view of the spa street across the river. Open 10:00–22:00 daily; wrapping a bath towel is allowed, which makes it easy for first-timers, and it is lit and atmospheric at night. Stroll the town, rebuilt after the 2020 floods, and try the other riverside baths such as Kanda-yu and Ekimae Onsen. About 10 minutes on foot from JR Amagase Station.

Because drilling is banned inside the national park, every bath in Unzen runs on naturally rising water.

Inside is a simple indoor bathroom with two tubs, hot and moderate, filled free-flowing with clear, slippery bicarbonate water; there is a drinking fountain of the spring too. No open-air bath or restaurant, but it opens 06:00–21:00 (last entry 20:30) and a room-only lodge next door costs ¥1,800 including the bath — a boon for travellers. Closed the fourth Monday. About 5 minutes on foot from JR Hinatayama Station; 10 parking spaces. For anyone wanting an unadorned everyday Kagoshima bath before or after Kirishima Shrine or the airport.

Hama-no-Yu is the city-run, old-fashioned public bath of this seaside spa: a classic sentō layout with an attendant's booth and two deep tubs, hot and tepid, brimming with alkaline simple spring water.
