The most popular of Kinosaki's seven public baths. In a building modeled on the Kyoto Imperial Palace, a waterfall rotenburo faces the hillside and a glass-roofed 'sky bath' sits indoors, all renovated in 2020. Overnight guests get free entry with the 'Yumepa' pass, so evenings are busy with yukata-clad bathers — go at 7 am when it opens.
The public bathhouse of Arima, one of Japan's three oldest hot springs. For ¥800 you can soak in the 'kinsen' — iron- and salt-rich water that turns rusty brown on contact with air, in pools at 42°C and 44°C. Under an hour by train from Kobe or Osaka, so an easy day trip. Free foot bath and drinking fountain outside. No tattoos.
A giant bath complex next to Tsutenkaku Tower in Shinsekai. The 'Europe zone' (Rome, Greece, Mediterranean) and 'Asia zone' (Bali, Persia) swap between men and women each month. There's also a swimsuit pool, stone saunas and hotel floors. Open 24 hours, so it doubles as a place to stay after the last train. Tattoos OK if covered with a sticker.
Kinosaki's flagship outer bath, praised as 'the best under heaven' by an Edo-period physician. Its cave bath carved into rock is the draw; the kabuki-theatre-style building is the town's landmark.
Sister facility to Kin-no-Yu. Clear carbonated and radon water that leaves skin silky, plus a steam sauna. Usually less crowded than Kin-no-Yu. ¥700 on weekends/holidays, ¥550 on regular weekdays.
An open-air-only bath at the edge of the Pacific. One of Japan's oldest springs, mentioned in the 8th-century Nihon Shoki; on rough days sea spray reaches the tubs. No roof, no wash stations.
Closest of Kinosaki's seven public baths to the station. A striking hexagonal lantern-motif window; indoor bath only, simple and quick.
The smallest and hottest of the seven baths — a little wooden bathhouse on the willow-lined canal, where you soak shoulder to shoulder with locals. Opens at 3 pm.
The bath tied to Kinosaki's founding legend. Popular for its cypress open-air tub and barrel baths facing the wooded hillside; at the quiet end of town. Opens at 3 pm.

Shirahama's other classic public bath, on the Yuzaki seafront near Saki-no-yu. Its draw: two distinct springs — Mabuyu and Miyukiyu — under one roof. 7 am to 10 pm, ¥420.
About 8 minutes from Arima-Onsen Station, a hotel day-bath offering both the iron 'gold' and clear 'silver' springs. ¥1,360 includes free towels and drinks, so arrive empty-handed. Open 9 am–9 pm (cleaning 11–1), longer than the public baths.
Four minutes from Hankyu Arashiyama Station and a short walk from Togetsukyo Bridge, Arashiyama's only dedicated day-use onsen. Mildly alkaline simple spring water in indoor, open-air, silky and sauna baths. Easy to slot between sights, with towel rental so you can come empty-handed. The changing room is small, so avoid peak hours. ¥1,200 weekdays, ¥1,400 weekends and holidays.
At the southern tip of Nara, directly opposite the Totsukawa Onsen bus center where Japan's longest local bus route (Yagi–Shingu) stops. A small all-timber bathhouse looking down on the Futatsuno dam lake. The whole village has pledged 'free-flowing spring water only', so nothing is recirculated. Free foot bath, hand bath and drinking fountain. Combine with the Kumano Kodo and Tanize suspension bridge.
A ryokan in Ogoto Onsen on the shore of Lake Biwa below Mt. Hiei, 20 minutes by JR from Kyoto Station. Day bathing is accepted 11:30–20:00, with pH-9 alkaline water indoors and in the rotenburo.

Everything is charged to a wristband and settled on exit. ¥1,000 weekdays.
Four minutes from Arisugawa Station on the Randen tram near Arashiyama, a day spa in Kyoto-style timber architecture. Chloride water from 1,200 m below fills rock rotenburo, pot baths and a spacious indoor pool; the men's side has a 'theater' sauna, the women's two saunas. Open until midnight, so it works after a day in Arashiyama. Restaurant on site. ¥1,200 weekdays; closed the third Monday.
A village-run public bath on the shore of Futatsuno Dam lake in Totsukawa, the village that declared all its baths 100% free-flowing. Attached to a seniors' centre, it's plain but pours 70°C bicarbonate-chloride water straight in with no recirculation. Handy on Tuesdays when nearby Iori-no-yu is closed. ¥600, 9:00–21:00, closed only Jan 1–2. Five minutes' walk from Totsukawa-Onsen bus stop.
Twenty minutes by train from Kyoto, the flagship ryokan of Ogoto Onsen on Lake Biwa's west shore.

The source bath of Ryujin Onsen, counted with Yunokawa and Kawanaka among Japan's 'three beauty baths'. It stands on the Hidaka River deep in the Kii mountains, with a cypress indoor bath and a rock rotenburo overlooking the stream. The silky bicarbonate water is famous for leaving skin smooth. ¥800, 7:00–21:00, open daily. An hour by car from Koyasan via the Koya-Ryujin Skyline, or about 80 minutes by bus from Kii-Tanabe.
A lakeside ryokan drawing 'Taiko Onsen' water from the site of Hideyoshi's Nagahama Castle.

Seven minutes' walk from Nagahama Station — easy to pair with the Kurokabe Square old town. About an hour from Kyoto by rapid train.
The village-run public bath of Tōsenji Onsen, the oldest spring in Totsukawa. pH 9.1 alkaline sulfur water flows fresh from the source even through the taps, leaving a faint sulfur scent and slippery skin. Just a stone open-air bath facing the gorge and an indoor tub—simple and ¥600. Handy on Route 168 en route to the Tanize suspension bridge or Kumano Hongū Taisha.
The only public bath in Miyazu, right next to Amanohashidate Station on the Kyoto Tango Railway — the gateway to one of Japan's Three Views. Named after the Monju bodhisattva of wisdom, it looks like a small ryokan. Magnesium-rich chloride water fills an indoor bath and hand-and-foot bath, with a free footbath outside. ¥800, 12:00–21:00. Perfect for a rinse while waiting for your train after walking the sandbar.
A long-established bath theme park on a hillside three minutes' walk from Hankyu Minoh Station in northern Osaka. The panoramic main bath and open-air tubs look out over the Osaka plain, and with stone-slab baths, a manga corner, games, stage shows and a buffet you can spend the whole day in lounge wear. Admission ¥1,813 on weekdays (¥2,253 weekends), dropping to a ¥922 evening rate after 17:00. Open until 23:45 — popular with hikers coming back from the Minoh Falls autumn foliage trail.
The only hot spring inscribed as a World Heritage Site that you can actually bathe in, listed together with the Kumano Kodo pilgrimage routes. A tiny hut over the stream in Yunomine — said to be Japan's oldest onsen at 1,800 years — shelters a tub hollowed from natural rock that fits two adults. The sulfurous water is said to change colour seven times a day and served pilgrims for ritual purification. Private 30-minute slots, ¥800, sign up at the public bathhouse (6:00–21:00). Waits of several hours are common on holidays; boil onsen eggs in the hot-spring trough while you wait.
At Kawayu, where 73°C spring water bubbles up through the bed of the Ōtō River, a giant outdoor bath is created every December to February by damming the river. Roughly 50 by 15 metres — big enough for 'a thousand people', as the name says — it's tempered to perfection by the river's cold flow. Free (donation box), 6:30–22:00, swimwear required, open to everyone. Bathing is suspended in bad weather or high water and opening dates shift from year to year. In summer you can dig your own pool in the gravel. Combine with Yunomine and Watarase for the three Hongu baths.
A village-run day bath in the Dorogawa onsen street at 820 m, the trailhead for sacred Mt Ōmine. Reopened in April 2024 after renovation, it heats its water with a wood boiler burning local forest thinnings. Yoshino-cedar indoor bath, open-air bath and a rest room; the mildly alkaline water leaves skin silky. ¥800, 11:00–20:00, closed Wednesdays. Pair it with the lantern-lit wooden inns, the 'Gorogoro' spring water (one of Japan's 100 famous waters) and Menfudō limestone cave for one of Kansai's best retro onsen strolls. Busy as a summer retreat.
A lone inn with its own spring near Ōmi-Shirahama, the pine-fringed white-sand beach on Lake Biwa's west shore. The simple carbonated iron spring (a cold mineral spring, heated) turns tea-brown on contact with air and is locally prized as a skin-beautifying bath that warms to the core. Drop-in bathing 9:00–20:00 (last entry 19:30), a modest ¥700; closed Mondays. The open-air bath is private-hire only (from ¥3,000 per 50 min), good for families and couples.

Day use may be unavailable when groups are staying, so phone ahead.
The town-run communal bath at the heart of Yumura Onsen in northern Hyōgo, where the 98 °C 'Arayu' source boils eggs and vegetables for visitors on the banks of the Haruki River. Bicarbonate water flows freely through separate men's and women's main baths, with an open-air tub, sauna, an assisted bath and an upstairs rest room. ¥500 for non-residents; open 9:00–21:00, closed on the 15th of each month.

A large super-sentō about 25 minutes from central Osaka on the Kita-Osaka Kyūkō line, ten minutes on foot from Minoh-Semba-Handai-mae Station (opened 2024). Certified therapeutic bicarbonate-chloride spring water feeds the open-air bath, joined by a high-concentration carbonated bath, pot tubs, lying baths and more — 17 tubs in all — plus a hot sauna with automatic löyly and an outdoor cool-down area.

A mountain hot spring in the temple-gate village of Kurama, about 30 minutes from central Kyoto on the Eizan railway, home of the tengu legends. The open-air Hōroku-yu sits in a cedar grove facing the Kitayama hills and becomes a snow-viewing bath in winter. The simple hydrogen-sulphide water carries a faint whiff of sulphur that suits the mountain air. The open-air-only course is ¥1,500 weekdays / ¥1,600 weekends (towels extra); the full day course with indoor bath, open-air bath, sauna, lounge, towels and robe is around ¥2,600 on weekdays. Open 10:00–21:00 every day, no reservation. Ten minutes on foot from Kurama Station or by free shuttle. The classic way to end a visit to Kurama-dera or the hike over to Kibune — for anyone who wants a genuine onsen in Kyoto.
Near the village office of Totsukawa, Japan's largest village, this is the public bath of Tōsenji Onsen, the oldest spring in the village. True to Totsukawa — the first place in Japan to declare all its baths 100% free-flowing — the roughly 60°C sulphur water is cooled without dilution and left to overflow. As the name suggests, the big draw is the streamside open-air bath at the bottom of a long staircase, where you soak facing a small waterfall; the water runs hot. There are also an indoor bath and sauna. ¥800 for adults, open 08:30–20:00, closed Thursdays. The lunch-only diner is known for its 'dam curry'. The nearby Izumi-yu is ¥100 cheaper, but come here for the waterfall. A remote spot about 3 h 40 min from Yamato-Yagi Station on Japan's longest local bus route.
A day-use hot spring in the Jūnibō forest of Kōnan, Shiga, near Ishibe, an old post town on the Tōkaidō. The two bathing areas, Shugen-no-yu and Momotsute-no-yu, alternate between men and women daily, each with an indoor bath, dry sauna and free-flowing open-air bath; the high-pH alkaline water feels slippery on the skin. Adults pay ¥800, and the complex also has a restaurant, gym, massage, pottery and craft workshops, an indoor onsen pool (late Apr–mid-Oct, extra) and a reservation-only campground. Open 10:00–22:00 (last entry 21:20); closed only over New Year and for maintenance. About 10 minutes by car from Kōsei Station on the JR Kusatsu line and close to Ritto-Kōnan IC — pairs well with the autumn-leaf temples of the 'Kōnan Sanzan'.
A town-run bathhouse right in front of Shirara-hama, the famous white-sand beach. Built like an old-fashioned sentō with an attendant's counter, its second-floor bathroom opens through big windows onto the beach, blue sea and sky — a ¥420 view bath you would never expect in a resort. The 66.8°C sodium-chloride 'Suzushi-yu' source flows freely, and the strongly salty water keeps you warm long after. Open 09:00–11:00 and 14:00–21:30 (last entry 21:00; 07:00–09:00 is residents only), closed Thursdays. Soap and shampoo sold for ¥40; no hair dryers. One of Shirahama's 'sotoyu' circuit with Saki-no-yu and Muro-no-yu — locals rinse off the sand after a swim and come straight in. About 15 minutes by bus from Shirahama Station to 'Shirarahama'.
A long-established ryokan at the gateway to Inunakiyama Onsen, about 30 minutes by car from Kansai Airport and the only place in Osaka Prefecture to call itself a spa 'village'. Inunakiyama is a Shugendō holy mountain said to have been opened by En no Gyōja; the gorge leading to Shippōryū-ji temple is dotted with waterfalls and ascetic training sites and is listed among Osaka's hundred finest green spots. In the indoor bath and the open-air bath facing the stream you soak in soft, clear simple water (sodium-bicarbonate-chloride) to the sound of the river. Day bathing: adults ¥900, children ¥400, 11:00–21:00 (last entry 20:00), irregular closures.

About 30 minutes by bus from JR Hineno or Nankai Izumisano stations to 'Inunakiyama', right by the stop. An onsen before or after a Kansai Airport flight, or a half-day escape from Osaka city.
A village-run day spa inside the Soni Kōgen Farm Garden at the foot of the Soni plateau, on Nara's eastern edge, where the pampas-grass meadows turn gold in autumn. The sodium-bicarbonate water is remarkably slippery and lives up to its 'beauty bath' reputation, leaving skin silky. The indoor hall has a free-flowing source tub, and the open-air bath looks out to the rock peaks of Kabuto-dake and Yoroi-dake and across the highland (a wood bathroom and a stone bathroom alternate weekly between men and women).

About 20 minutes by car from Yōkaichi IC or 35 minutes by bus from Ōmi Railway Yōkaichi Station. Pair with Eigen-ji's November foliage.
Of the inns at Yunohana Onsen — Kyoto's 'back parlour' spa in the Tamba hills outside Kameoka, about 25 minutes by train from Kyoto Station — this is the easiest for day bathing. Fields and woodland spread across its large grounds, and the main bath and garden open-air bath look out on the countryside through the seasons. The water is a clear, soft, mildly radioactive (radon) simple spring. Day bathing: adults ¥1,000, children ¥500; weekdays 12:00–21:00 straight through, weekends, holidays, eves of holidays and Obon in two sessions, 12:00–15:00 and 17:30–21:00.

About 15 minutes by car from JR Kameoka Station (ask about pick-up) or 10 minutes from Kameoka IC. Combine with Arashiyama for a Kyoto onsen day trip.
A hot-spring resort on the Rurikei plateau in Nantan at about 500 m, roughly an hour by car from Kyoto city, at the entrance to the scenic Rurikei gorge trail. Formerly 'Kyoto Rurikei Onsen for REST RESORT', it was renovated and renamed in 2025. The water is a mildly radioactive radon spring; besides the gender-separated 'Ruri-yu' halls, open-air baths and single-person ceramic pot baths, there is a swimwear zone where couples and families bathe together, along with a pool and saunas. Day admission (including the pool and swimwear area) is ¥800 for adults and ¥400 for children on weekdays, ¥950 and ¥500 on weekends and holidays; towel set ¥300, swimwear rental ¥400.

Barbecue, a kids' area, the GRAX glamping site and a hotel share the grounds, and at night the 'Synesthesia Hills' illumination is a draw. Keihan Kyoto Kōtsū bus to 'Rurikei Onsen', or about 30 minutes by car from Kameoka IC.
A big bath complex on the Kanzaki River in Toyonaka, about 20 minutes north of Umeda, whose main draw is an authentic Korean-style jjimjilbang — rare in Kansai. Sauna fans rate it highly for the large natural-spring open-air bath, cut-stone bath, pot baths, a sauna with löyly sessions every two hours, cold plunge and plenty of chairs and loungers for outdoor rest. The extra-charge 'Bijōbō' zone offers several low-temperature sauna rooms at 40–70 °C and a dome-shaped hanjeungmak at around 100 °C — Korea's steam-bath culture in Osaka. Entry: adults ¥900 on weekdays, ¥1,000 on weekends and holidays; children ¥500/¥550. Open 10:00–02:00 (last entry 01:00), every day.

The public bath at the heart of Yunomine Onsen, one of Japan's oldest springs, where pilgrims purified themselves before Kumano Hongū Taisha. The building, renovated in 2022, also serves as reception for the World Heritage 'Tsuboyu'. There are three bathrooms: the 'Ippan-yu' with hot and tepid tubs (adults ¥400, shampoo provided), the concentrated 'Kusuri-yu' filled with undiluted source water (¥600, no soap allowed) and a 30-minute private family bath (¥700), all sulphur-scented sodium-bicarbonate-chloride water ranging from milky to clear. Tsuboyu (¥800, 30-minute slots) can mean a wait of hours when busy, so the clever order is to take a number and warm up in the public bath first. Open 06:00–21:00 (last entry 20:30), irregular cleaning closures. The village also has the 'Yuzutsu', a 90 °C source where you boil eggs and vegetables, and is the trailhead of the Dainichi-goe section of the Kumano Kodō. About 2 hours by bus from JR Kii-Tanabe or Shingū stations to 'Yunomine Onsen', right by the stop; 46 parking spaces.

A stay-as-long-as-you-like hot spring resort among the fields of Takatsuki, in northern Nagahama near the top of Lake Biwa.

The men's side has a high-temperature sauna and bubble bath, the women's an herbal mist sauna and jet bath, each with a cold plunge and outdoor cooling area. Inside are a lounge with co-working space, nap 'nest rooms', a restaurant and even lodging, and the complex is open around the clock (bathing suspended during cleaning).

A day-bath house standing in a grove a little way from the Shirahama spa street.

Yamano-yu is where you can bathe in the headwater spring of Inunakiyama Onsen, the only onsen village in Osaka Prefecture. About 30 minutes by Nankai bus from Izumisano Station, it sits at the far end of the valley-side onsen hamlet, offering a slightly milky simple sulfur cold spring in kake-nagashi style. The silky water is gentle on the skin and well regarded as a beauty bath. The inn no longer takes overnight guests and operates for day bathing only, so it is a place to simply face the water. Afterwards, unwind in the paid lounge. Shipporyuji, a Shugendo holy site, is close by, making it an ideal stop after a mountain walk - and it is only about 25 minutes by car from Kansai International Airport.

Open-air baths include a rock bath and the natural mineral bath Sosei-no-Yu, while inside are high-concentration carbonated baths; the ceramic-plate bath (ganzanyoku) is a signature. The free-flowing water comes from a hidden spring said to have been frequented by Azai Nagamasa and his wife Oichi. The spacious hall, decorated with flower arrangements and artworks, has a restaurant and lounges for a lazy half day. About 15 minutes by car from Nagahama IC, with parking for 180 cars.

A historic ryokan in Kita Ward, Kobe - said to be the oldest inn in Arima Onsen, founded in the Kamakura period. Beloved by literary figures including Junichiro Tanizaki, the interior retains a retro Showa-era atmosphere. The bath uses a distinctive semi-mixed style: changing rooms are separate, but the tubs connect, letting couples talk without seeing one another (the turbid gold water hides the body). The water is Arima's famous iron-rich, reddish-brown kinsen spring, enjoyed 100% free-flowing with no heating or added water. Day bathing runs 11:00-14:00 at 2,250 yen (face towel included; bath towel rental 300 yen), closed Mondays and on facility closure days. About 4-5 minutes on foot from Arima Onsen Station on the Kobe Electric Railway. Pair it with the Kin-no-Yu and Gin-no-Yu public baths to touch 1,300 years of Arima history.
