Onsen and ryokan in Japan: where the bathing is real

♨️ Onsen / Ryokan · 143 destinations · 316 activities

Japan has thousands of onsen, but there is a wide gap between a decent municipal bathhouse and a hot spring town that justifies two nights. These destinations are ranked by how much bathing culture actually weighs in them, not by fame. Two warnings that keep coming up: most of them only make sense if you sleep there, and tattoo policy changes from one bathhouse to the next, so check before booking.

The destinations, by real weight

What to do exactly

Beppu — 16 activities

• Hells Tour (Jigoku Meguri) 2.5 h must-see

  A tour of hot springs in impossible colours, not suitable for bathing. Planning warning: five of the seven hells are in Kannawa and two in Shibaseki, three kilometres away. The water in the Umi Jigoku is at 98 degrees and several pools sit at around 90: they are to be looked at, not bathed in, and nobody should lean out over the fences or go near the drainage channels.

• Kannawa Mushiyu, the herbal steam bath 0.75 h must-see

  Founded in 1276 by the monk Ippen. You lie for eight or ten minutes on a bed of sekisho, a medicinal herb, inside a stone chamber full of natural steam, then rinse off in hot-spring water. It is the only place in Japan preserving this form, and it accepts tattoos.

• Hot Sand Bath (Sunayu) 1.5 h must-see

  You are buried in hot volcanic sand on the beach, an experience unique to Beppu. To be precise: there are two different sand baths in Beppu, the indoor one at Takegawara and the beach one at Kamegawa. There is a strict limit of about fifteen minutes, get out at the first sign of dizziness, and it is not advised with high blood pressure, heart disease, pregnancy or alcohol.

• Beach sand bath at Shonin Park 1.5 h booking

  Bayfront complex opened in the summer of 2025 on the former Kamegawa beach. You lie for about fifteen minutes under sand heated by thermal water; the sand is reheated nine times a day and rotated rather than reused.

• Beppu Rakutenchi 3.5 h

  Opened in 1929, the oldest amusement park in Kyushu and a gem of retro styling. You reach it on a 260-meter funicular at a 30-degree gradient, in dog- and cat-shaped cars running since the park was founded; it has Japan's only double ferris wheel, duck races and a hot spring bath with views included in the ticket.

• Hyotan Onsen 2.5 h

  Three stars in the Michelin guide and open until one in the morning: hot-water cascades for neck massage, a sand bath, steam baths and private family baths, plus steam cooking and a famous pudding.

Noboribetsu — 7 activities

• Jigokudani (Hell Valley) 1 h must-see

  An 11-hectare volcanic crater with steaming sulfur vents and boiling pools that supply hot-spring water to the whole town.

• The nine waters trail 5 h must-see

  Noboribetsu is the only spa town in Japan with nine distinct water types in one village, sulphurous, ferrous, saline, alum, acidic, fed by the Jigokudani at some ten thousand tonnes a day. They call it the department store of onsen, and several hotels allow day bathing, so you can compare them in an afternoon.

• Bathing at a Ryokan Onsen 1.5 h

  The town's ryokan draw water directly from Jigokudani; many, like Dai-ichi Takimotokan, let day visitors pay to use their baths without staying overnight.

• Day bathing at the Dai-ichi Takimotokan 2.5 h

  The village's great historic bath, fed by five different springs across a huge hall of pools with windows over the Jigokudani. It is one of the best modern indoor baths in Japan, and the price drops from four in the afternoon.

• Karurusu Onsen 4 h booking

  It does belong to the municipality, about eight kilometres inland. Its water is simple, very soft and low in minerals, the opposite of the sulfur of the Jigokudani, with a tradition of prolonged therapeutic bathing and a rural, quiet atmosphere.

• Oyunuma River Natural Footbath 0.7 h

  A stretch of the stream flowing down from Lake Oyunuma cools just enough for a foot soak, along a wooden walkway through the forest.

Kinugawa Onsen — 6 activities

• Hot spring ryokan over the gorge 2 h must-see

  Traditional ryokan perched directly over the Kinugawa River canyon, many with open-air baths (rotenburo) overlooking the gorge.

• Day bathing at the large hotels 1.5 h

  Several ryokan open their baths above the river to visitors who are not staying, a convenient option if the town is done as a day trip.

• Foot baths beside the station 0.5 h

  Free foot baths right as you step off the train, the quickest way to try the town's waters.

• Kawaji Onsen 2 h

  A neighbouring hot spring town with much softer water and a quiet atmosphere, a good counterpoint to the bustle of Kinugawa's big hotels.

• Remote inns of Okukinu 14 h booking

  Four thermal inns upstream reachable only on foot or by shuttle, with no direct road access: the real disconnection in this area.

• Side trip to Yunishigawa Onsen 3 h

  Further up the valley, an even more remote and quiet hot spring village, traditionally linked to defeated Heike clan survivors; reachable by bus from Kinugawa Onsen.

Yufuin — 6 activities

• Day baths at ryokan with views of Mount Yufu 1.25 h

  Three establishments open their bath to non-guests, in narrow midday and early-afternoon windows, with large panoramic rotenburo. Confirm the hours on the day itself: they change often and are suspended when the hotel is full.

• Onsen with views of Mount Yufu 1.5 h booking

  Open-air hot spring baths with views of Yufuin's sacred mountain.

• The town's communal baths 1 h

  Yufuin keeps seven neighbourhood-run baths, nearly all unstaffed and with an honesty box, between 100 and 500 yen: Yunotsubo, Edo in origin; Kase-no-yu, founded in 1876; Kawanishi, with iron-rich water; and several more. Bring your own soap and towel. Warning: Shitanyu, the one by the lake, is a mixed bath.

• Yunohira Onsen and its cobbled slope 2.5 h

  About fifteen kilometres from the centre, an Edo-era spa climbing a 300-year-old cobbled slope, with wooden inns and four communal baths at 100 or 200 yen. It is what Yufuin was before tourism: quiet, aged and without a single soft-toy shop.

• Shitanyu 1 h

  A thatched-roof public bath built on the shores of Lake Kinrin, one of Yufuin's most photographed onsen.

• Tsukahara Onsen and its steaming crater 2 h

  On the slope of Mount Garan, at 700 metres: strongly acidic, iron-rich water, among the most acidic in Japan, translucent green, and a short trail up to a steaming volcanic crater. The access road is narrow and it is awkward without a car.

Ginzan Onsen — 4 activities

• Evening Stroll Among the Illuminated Ryokan 1.5 h must-see

  Gas lamps lit at dusk over the wooden inns. In winter the stroll is regulated and cannot be improvised: cars do not enter the village, day visitors park at the Taisho Roman-kan and ride a shuttle in (¥500 a day in the 2025-26 season), and the lantern hours are covered by a bus from Oishida station that is booked online only, paid by card, and closes at midnight the day before. Anyone staying at a village ryokan skips all of it. The terms change every season — in the 2024-25 trial, afternoon entry was cut off at 16:00 — and the 2026-27 scheme had not been published as of October 2026: check the official site before going.

• Foot Bath (Ashiyu) by the River 0.5 h

  A free hot-spring foot bath right in the centre of the village.

• Shiroganeyu public bath 1 h

  A modern public bath beside the river, open to any daytime visitor: the only way to soak in the hot spring water without staying at one of the village's ryokan.

• Fujiya Ryokan, architecture by Kengo Kuma 0.5 h

  Facade of one of the town's oldest ryokan, renovated by architect Kengo Kuma, blending traditional wood with contemporary design.

Hakone — 7 activities

• Onsen Bath at the Ryokan 2 h must-see booking

  A traditional hot-spring bath, the central experience of a stay in Hakone.

• Long soak at Tenzan Tojikyo 3 h

  A hot-spring complex in the toji style, the long cure, beside the Sukumo river, with outdoor rock baths and rest rooms. Cash only, discourages groups over six and refuses organised tours: it is a place of cure, not leisure.

• A whole afternoon with no plan at a ryokan with a private rotenburo 5 h booking

  A deliberately empty block: bath, yukata, kaiseki dinner in the room and nothing else. This is how Japanese travellers use Hakone and what foreign itineraries miss most.

• Private open-air bath at Hakone Yuryo 2 h booking

  19 private outdoor baths spread through a forest, three minutes by free shuttle from Hakone-Yumoto. With the Hakone Free Pass the hut rental drops to around 600 yen for two hours.

• Route of the seven historic onsen of Hakone 4 h

  The Hakone Nanayu, the seven springs that already existed in the Edo period, each with different chemistry and temperature. They make clear that Hakone is not one onsen but an archipelago of waters.

• Okada Museum of Art 2 h

  Broad collection of classical Asian art (Japanese, Chinese, Korean) in a building with a huge exterior mural and a thermal footbath facing the artwork. It is the most expensive museum in Hakone at 2,800 yen, with 200 yen off with the Hakone Free Pass. The footbath under the giant mural costs 500 yen on its own or is included with admission.

Kusatsu Onsen — 5 activities

• Yubatake, the hot-water field 1.5 h must-see

  Kusatsu's steaming heart: a wooden channel in the centre of town carrying much of the more than 4,000 liters per minute of hot-spring water that make this Japan's largest natural spring source, lit up at night.

• Otakinoyu and the stepped awase-yu bath 1.5 h

  A bathhouse with five wooden tubs from 38 to 46 degrees that you work through in order, raising the temperature little by little: the traditional method for handling Kusatsu's water.

• Gozanoyu bathhouse 1 h

  A bath rebuilt in Edo style next to the Yubatake, with two waters from different sources and new timber that smells of cypress.

• The timed bathing ritual (jikan-yu) 1 h

  An Edo-period tradition still practiced: exactly three minutes submerged in water above 45 degrees, everyone at once and on a leader's call.

• The village's communal baths 1 h

  Kusatsu has some eighteen free communal baths scattered through its streets, but only three (Shirahata, Jizo and Chiyo) are open to visitors: the rest are for residents only, and that should be respected.

Kakunodate and Lake Tazawa — 5 activities

• Tsuru-no-Yu, the milk-white hot spring 2 h must-see booking

  The oldest of the Nyuto springs and the one in every photograph: rows of thatched buildings with earthen floors, and an outdoor pool with a sandy bottom through which the source bubbles up, the water opaque white with sulphur. The large rotenburo is konyoku (mixed) and women enter along their own covered passage; there are also two women-only outdoor baths, so mixed bathing is never compulsory. Day bathing costs about 700 yen from 10:00 to 15:00 and is not offered on Mondays (if the Monday is a public holiday, it closes the Tuesday instead). Staying overnight is booked by telephone and only by telephone (0187-46-2139): the line opens at 7:00 on the 1st of the month, six months ahead, and fills within minutes.

• Nyuto under the snow 3 h booking only 15 Dec - 31 Mar

  From January to March two metres of snow pile up and the white walls around the pools reach shoulder height: this is when Nyuto makes the most sense and when it is hardest to get a room. The Ugo Kotsu bus from Tazawako station runs all year (about 50 minutes and 950 yen to Nyuto Onsen, 850 yen to the Tsuru-no-Yu turn-off), but departures are few and the last afternoon one is early; Tsuru-no-Yu collects its guests at the Alpa Komakusa stop because the final track is not always cleared. A taxi from the station is around 7,000 yen. Driving up in a hire car without winter tyres is not an option.

• The seven baths of Nyuto (yumeguri) 4 h

  Nyuto is not a village but seven inns scattered through the forest, each with its own source: ten different waters, from the milky white of Tsuru-no-Yu to the dark Kuro-Yu and the iron-rich Myo-no-Yu. Anyone staying at one of the seven can buy the Yumeguri-cho, an 1,800 yen booklet good for one bath at each plus free use of the shuttle minibus that links them; if you are not staying you can buy the 600 yen map, which covers only the minibus, and pay for each bath separately: between 520 and 800 yen. Mind the hours: most stop admitting day bathers at 15:00 or 16:30.

• How a mixed bath (konyoku) works in Nyuto 0.5 h

  Worth knowing before you arrive rather than on the doorstep: the mixed baths at Nyuto are the large rotenburo at Tsuru-no-Yu, both outdoor pools at Magoroku, the one at Kaniba and those at Myo-no-Yu; Okama and the Kyukamura have all baths separated by sex, and most of the others also have a women-only pool. You bathe naked, the small towel never goes into the water, and swimsuits are not allowed except where signs say otherwise. Several places set aside a women-only time slot, posted at reception on the day, and some lend or sell a yuamigi, the bathing wrap that lets you enter covered. The water at Tsuru-no-Yu is so opaque that once you are in, nothing shows.

• Kuro-Yu, the hot spring that closes for half the year 1.5 h only 15 Apr - 8 Nov

  Wooden, thatch-roofed buildings at the end of a track, with two sources, a cascade bath where the water hammers down on your shoulders and greyish-white sulphur waters. It is one of the few hot springs in Japan that shuts completely for the winter: open from mid-April to early November and that is that. Day bathing costs 800 yen adults and 400 yen primary school, 9:00-16:30 (Wednesdays only 9:00-11:00), with towel hire at 550 yen. It has a mixed section and gender-separated ones.
