Japan's Famous Day-Trip Onsen: Historic Public Bathhouses You Can Just Walk Into
Japan's Famous Day-Trip Onsen: Historic Public Bathhouses You Can Just Walk Into
You do not need a ryokan booking to bathe in Japan's best-known hot spring water. Most onsen towns keep public bathhouses, called soto-yu (外湯, "outside baths") or kyodo yokujo (共同浴場, shared baths), that anyone can walk into for a few hundred yen, and in two villages for nothing at all. In several towns the bathhouse is the oldest building on the street. This guide covers 13 onsen towns where the public bath is the reason to go, starting with the most famous of them, Dogo Onsen Honkan in Matsuyama. For the opposite kind of trip, a single inn at the end of a mountain road, see the guide to hitō, Japan's hidden hot springs.
Prices and hours below are the ones posted in autumn 2026. Several of these baths have raised their fees in the last two years, so check the official site before you go.
- Wash first, then soak. Sit at a tap, wash and rinse all over, and only then get in. Your small towel stays out of the water; fold it on your head or leave it on the edge. At Shirahama's Sakinoyu the water runs into the sea, so soap and shampoo are not allowed at all.
- Bring a towel, and coins. The bigger bathhouses sell or rent towels, but Nozawa's village baths and Kusatsu's free kyodo-yu have no towels and no soap. Nozawa's 13 baths are free, with a box for donations, so carry some 100-yen coins.
- Tattoos. Several of these say plainly that tattoos are fine: all three Dogo bathhouses, Kusatsu's Sainokawara and Otakinoyu, Kinosaki's public baths, and Takegawara in Beppu. Ibusuki's Saraku says yes with conditions, so read them before you pay. Nozawa's free baths post no rule. For the rest we could not find a stated policy, so ask at the counter.
- Plan for the last entry, not the closing time. Tickets stop selling 30 minutes to an hour before closing: 22:30 for Dogo Onsen Honkan's ground floor, 20:30 for Tsuboyu, 20:00 for the sand bath in Ibusuki. Shibu's Oyu lets day visitors in only from 10:00 to 17:00.
- Check the closing day. Arima's two baths close on alternate Tuesdays, Yamanaka's Kikunoyu on the second and fourth Tuesday, Takegawara on the third Wednesday. Two of Kinosaki's seven baths are shut for rebuilding as of October 2026.
- The village baths belong to the neighbourhood. In Nozawa, Kusatsu and Shibu, locals run the baths and use them before work and after dinner. Keep your voice down, and if the water is too hot for you, ask whoever is already in before you run the cold tap.
All of these can be done as a day trip from the nearest city except Hirauchi on Yakushima, which needs a flight or a ferry first. The village baths are at their best in the early morning, so stay the night if you can.

Dogo Onsen (Matsuyama, Ehime)
Dogo counts with Arima and Shirahama, both further down this page, as one of Japan's three ancient hot springs, the ones named in the oldest chronicles. It has three public bathhouses within a few minutes' walk of each other, all on the same spring. The Iyotetsu tram from JR Matsuyama Station runs to Dogo Onsen, the end of the line.
Dogo Onsen Honkan
The three-storey wooden bathhouse from 1894 that most people picture when they hear the word onsen, and the first public bathhouse listed as an Important Cultural Property. A drum in the little tower on the roof is beaten at 6:00 to open the bath, and again at noon and 18:00. After five and a half years of repair work, done a section at a time while bathing carried on, the whole building reopened in July 2024, with new prices. There are four ways in:
- Kami-no-Yu, ground floor only: 700 yen, 6:00 to 23:00, last tickets 22:30.
- Kami-no-Yu with the second-floor hall: 1,300 yen. You rest in a yukata afterwards with tea and a snack. 6:00 to 22:00, last tickets 21:00, one hour.
- Tama-no-Yu (霊の湯), the smaller granite bath, with a second-floor room: 2,000 yen, last tickets 21:00, one hour.
- Tama-no-Yu with a private third-floor room: 2,500 yen, last tickets 20:30, an hour and a half.
The ground floor is the cheap way in and the one with the queue; on weekends it is busy from mid-morning. The paid rooms upstairs are worth it once, for the building rather than the bath. The Honkan closes for one whole day each year for cleaning, which in 2026 is Tuesday, December 1.
Asuka-no-Yu
The annex, opened in 2017 behind the Honkan and built in the style of the Asuka period, the era of the oldest records of Dogo. Unlike the Honkan it has an open-air bath. The ground-floor bath is 610 yen, 6:00 to 23:00 with last tickets at 22:30; rooms upstairs cost more.
Tsubaki-no-Yu
The bath people who live in Dogo actually use: plain, quieter, and the same water. 500 yen since May 1, 2026, open 6:30 to 23:00 with last tickets at 22:30.
Central Japan (Gunma, Nagano and Ishikawa)
Kusatsu Onsen (Gunma)
A mountain town built around the Yubatake, a field of wooden channels where strongly acidic water steams down to cool before it reaches the inns. The bus from JR Naganohara-Kusatsuguchi Station takes about 25 minutes. The town runs three paid bathhouses, and their shared FAQ says tattoos are not refused. Sainokawara Rotenburo is a large open-air bath, with men's and women's sides, at the top of a park of steaming streams west of the Yubatake: 800 yen, 7:00 to 20:00 from April to November and 9:00 to 20:00 from December to March, last entry 19:30. Otakinoyu has indoor and outdoor baths and a set of awase-yu pools at stepped temperatures that you work up through: 1,200 yen, 9:00 to 21:00, last entry 20:00. Kusatsu also has free kyodo-yu kept by the neighbourhoods, and three are open to visitors: Shirahata-no-yu beside the Yubatake, Chiyo-no-yu and Jizo-no-yu. They are small, very hot and have nothing in them but the bath.
Nozawa Onsen (Nagano)
A ski village with 13 soto-yu, all free, kept since the Edo period by the yunakama, groups of villagers who clean and run them. Oyu, the wooden bathhouse in the middle of the village, is the one in the photos. Most open roughly 5:00 to 23:00 (from 6:00 in winter), but each posts its own hours and cleaning time on the door. There is a box at the entrance; put in a coin or two. The water comes straight from the source and is often too hot to sit in for long, there is no soap and no towel, and the changing area is a shelf in the same room. No tattoo rule is posted. The bus from Iiyama Station on the Hokuriku Shinkansen takes about 25 minutes.
Shibu Onsen (Nagano)
A narrow lane of old wooden inns with nine numbered soto-yu along it. Guests at Shibu's inns get a key that opens all nine and a towel to stamp at each one; doing the whole round, ending at Oyu (number nine), is the kyu-to meguri. Day visitors cannot do this. The eight smaller baths are for staying guests only, and a day visitor can use just Oyu: 800 yen, 10:00 to 17:00. Buy the ticket at the tourist information centre or one of the inns that sell it, and someone from a nearby inn unlocks the door for you. So if the nine-bath crawl is the point, stay the night. Shibu is a short way from Yudanaka, the last stop on the Nagano Electric Railway.
Yamanaka Onsen (Kaga, Ishikawa)
A riverside town in the Kaga hills where Bashō stopped on his journey to the deep north in 1689 and wrote about the water. Its sōyu, the town bath, is Kikunoyu, and the men's and women's baths are in separate buildings facing each other across a small square; the women's side shares its building with the Yamanaka-za theatre. 500 yen since May 2025, 6:45 to 22:00, closed on the second and fourth Tuesday (the next day if that is a holiday). Buses run from JR Kaga Onsen Station.
Kansai (Hyogo and Wakayama)
Kinosaki Onsen (Toyooka, Hyogo)
The town built for bath-hopping: seven soto-yu along a willow-lined canal, and people walking between them in yukata and geta all evening. A single entry is 800 yen, and the Yumepa day pass, 1,500 yen, covers every bath that is open that day; if you stay at an inn in town, it gives you the pass. Visit Kinosaki says people with decorative tattoos are allowed in all seven. As of October 2026 only five are open: Satonoyu, by the station, has been closed for rebuilding since April 2024, and Kounoyu is closed for repairs until October 30, 2026. Ichinoyu, with its bath in a cave, and Goshonoyu open from 7:00; the smaller ones open in the afternoon, most close at 23:00, and each closes one day a week, on different days. The limited express from Kyoto or Osaka takes about two and a half hours.
Arima Onsen (Kobe, Hyogo)
The second of the three ancient hot springs, in the hills behind Kobe, with two public bathhouses owned by the city of Kobe. Kin-no-yu has the kinsen, the "gold" water, which is iron-rich and salty and comes out of the source a cloudy rust brown: 800 yen (650 yen on weekdays), 8:00 to 22:00 with last entry at 21:30, closed on the second and fourth Tuesday and January 1. Gin-no-yu has the clear ginsen, a carbonated and radium spring: 700 yen (550 yen on weekdays), 9:00 to 21:00 with last entry at 20:30, closed on the first and third Tuesday and January 1. When a Tuesday is a holiday, the bath opens and closes the next day instead. A ticket for both is 1,200 yen. Kin-no-yu is small and packed on weekends. Both are about a five-minute walk from Arima Onsen Station on the Kobe Electric Railway.
Yunomine Onsen (Tanabe, Wakayama)
A small village near Kumano Hongu Taisha where pilgrims on the Kumano Kodo bathed before worship. Tsuboyu, a rock pool in a wooden hut over the stream, is part of the Kumano World Heritage site, and it is a public bath you rent in turns: 800 yen for 30 minutes, from the ticket machine at the village bathhouse, 6:00 to 21:00 with last tickets at 20:30. It holds two or three people, so at busy times the wait is long. If you only want to bathe, the bathhouse next door is quicker: 400 yen for the ordinary bath and 600 yen for the kusuri-yu, filled with untreated source water. In the stream outside is a boiling-hot spring where people cook eggs.
Shirahama Onsen (Wakayama)
The third of the ancient hot springs, a beach resort on the Kii Peninsula. Sakinoyu is a set of rock pools on the tip of a headland, so close to the sea that the waves break over the rocks below you; the men's and women's pools are separate. 500 yen. Hours change with the season: 8:00 to 17:00 from October to March, 8:00 to 18:00 from April to June and in September, 7:00 to 19:00 in July and August, with last entry 30 minutes before closing. The water runs straight into the sea, so no soap or shampoo; towels are 200 yen. There is no regular closing day, but it shuts now and then for maintenance. Buses run from JR Shirahama Station.
Kyushu (Oita, Saga and Kagoshima)
Takegawara Onsen (Beppu, Oita)
Beppu's oldest public bath, founded in 1879; the present building, with its curved tiled gable, dates from 1938. It is a ten-minute walk from JR Beppu Station. The plain bath is 300 yen, 6:30 to 22:30. The reason most visitors come is the sand bath: you lie down in a yukata and an attendant shovels sand heated by the spring over you. It costs 1,500 yen, the plain bath included, and runs 8:00 to 22:30 with last entry at 21:30. No bookings of any kind, by phone or online, so you queue at the counter. Closed on the third Wednesday of the month (the next day if that is a holiday). Beppu promotes itself as tattoo-friendly, and Takegawara, run by the city, accepts tattoos.
Takeo Onsen (Saga)
You walk in through the Romon, a vermilion two-storey gate from 1915 built without nails, designed by Tatsuno Kingo, the architect of Tokyo Station. Behind it is Moto-yu, a wooden bathhouse from 1876, with a hot bath and a cooler one side by side. 500 yen, from 6:30 in the morning, with last entry at 23:00 according to the local tourist association. The gate is lit up after dark. It is about 15 minutes on foot from Takeo-Onsen Station on the Nishi-Kyushu Shinkansen.
Ibusuki Onsen (Kagoshima)
At Saraku, the city's sand bath on the beach, you change into a yukata, lie down under a roof on the shore and staff bury you up to the neck in sand heated by the spring below. Ten minutes is plenty; after that you rinse off and use the indoor bath. 1,500 yen with the yukata (2,000 yen in Golden Week, Obon and over New Year), or 800 yen for the indoor bath alone. 8:30 to 21:00, last entry 20:00, and on weekdays the sand bath stops taking people from 12:00 to 13:00. It closes for maintenance twice a year, in 2026 from December 14 to 18. Bring a towel or buy one there.
Hirauchi Kaichu Onsen (Yakushima, Kagoshima)
A few pools in the shore rocks on Yakushima's south coast that sit under the sea most of the day. You can bathe only for about two hours around each low tide, so look up the tide table before you set out. It is mixed bathing; swimsuits are not allowed, but you can wrap yourself in a towel. There is no changing room, only the rocks. Instead of an entry fee there is a box for a cooperation fee of a few hundred yen, which pays for upkeep. A car is the practical way to get there.
Before You Go
Check the official site for the bath's current price and closing days, bring a towel and some cash, and plan around the last entry rather than the closing time.
For hot springs at the end of a long mountain road or trail, see the hitō guide.
