Day-use baths in Tokyo, Kanagawa, Saitama and Chiba — including Hakone and Yugawara.
Using Tokyo as a base, the choice of onsen you can reach and return from in a day is bigger than you might think: natural-spring spas inside the city, Hakone and Yugawara, Chichibu and Kawagoe, the Bōsō peninsula — real hot springs within one or two hours by train.
This list gathers day facilities in Tokyo, Kanagawa, Saitama and Chiba. Leave in the morning, be back by evening, no hotel needed. Weekends get crowded, so aim for weekdays or right after opening.
Five minutes by shuttle from Hakone-Yumoto Station, a day-use-only bathhouse in the hills along the Sukumo River. Terraced rock rotenburo, a cave bath and a lukewarm pool invite long soaks. No reservation needed; rest rooms, restaurants and a reading lounge make it easy to stay half a day. Tattoos not permitted.
Two halves: the swimsuit spa zone 'Yunessun' and the traditional nude 'Mori no Yu'. Wine baths, coffee baths and water slides make it family-friendly and an easy first onsen for visitors. Tattoos allowed if covered with a sticker. Dynamic pricing in 2026: passport (both zones) from ¥3,500, swimsuit zone from ¥2,500, Mori no Yu only from ¥1,500.
An urban spa in front of Toshimaen Station, 20 minutes from Ikebukuro on the Seibu line. Natural hot-spring water drawn from 1,445 m feeds an open-air bath overlooking a Japanese garden, plus a swimsuit 'Bade' pool zone. Adults and teens only (junior high and up), so it stays quiet. Lounges, a restaurant and body care invite long weekday afternoons. No tattoos.
Three minutes by free shuttle from Hakone-Yumoto. A farmhouse-style day spa whose 19 private open-air rooms are the draw (reserve ahead). The löyly sauna sessions in the main bath are popular too.
A large day-spa 12 minutes from Hakone-Yumoto Station, open 23 hours (10 am to 9 am). A 17-metre rooftop open-air bath, garden waterfalls and private baths. Overnight stays cost extra.
A day-spa on the hillside above Yumoto with five private spring sources feeding open-air, lie-down and jet baths. The ¥1,000 early-morning session (6–9 am) is among the cheapest soaks in Hakone.
Directly behind Hakone-Yumoto Station, a 3-minute climb up steps: a rustic wooden bathhouse with its own free-flowing spring and an open-air bath. Shōwa-era charm and surprising quiet for a station-front spot. Private indoor bath (¥1,000/45 min + entry) and a ¥200 footbath.
A town-run day spa named after Yugawara's ancient name. Set on a rise above the Fujiki River near Manyo Park, with a large indoor bath, a mountain-view rotenburo, sauna, tatami lounge and restaurant. Admission drops to ¥600 after 19:00, so locals stroll the onsen street first and bathe in the evening. 12 minutes by bus from Yugawara Station to the 'Kogome-no-yu' stop.
Eight minutes from Shimura-sakaue Station in Itabashi, one of Tokyo's most atmospheric super-sento, built around a Showa-era mansion and dry-landscape garden. Free-flowing olive-green spring water in the rotenburo, high-concentration carbonated bath, stone sauna and a soba restaurant. ¥970 weekdays, ¥1,300 weekends and holidays; open until midnight. No tattoos.
In the hills of Tokigawa, Saitama, a popular day spa styled as a 1950s–60s Japanese town, complete with enamel signs and an old-fashioned sweet shop. Strongly alkaline (pH over 10) 'beauty' water that feels slippery on the skin, indoors and outdoors. Opens at 5 am on weekends for early bathers. ¥980 weekdays. About 1.5 hours from Ikebukuro by Tobu Tojo Line and town bus.
A day-use-only onsen on the Otaki side of Yoro Valley on the Boso Peninsula, near Awamata Falls. A rotenburo looking over wooded hills and a timber indoor bath hold the dark-tinted alkaline water typical of Boso. Popular after hikes and waterfall walks; towel and robe rental mean you can come empty-handed. Closes early at 18:00; Wednesdays off.
A ryokan-style day spa on a hill among mandarin groves, away from Yugawara's main street. The draw is a rotenburo with a sweeping view of Sagami Bay, lit up at night. Two bathrooms alternate daily between men and women, and the water is drinkable. Free tatami rest hall and restaurant. ¥1,380; bring a towel. Closed Thursdays except holidays, March and August. Bus from Manazuru or Yugawara Station.
Kamata, 15 minutes by train from Haneda Airport, has Tokyo's densest cluster of 'kuroyu' black-water springs. Kaiseiyu, founded in 1929, is the classic: a coffee-dark natural bicarbonate bath, a high-concentration carbonated pool and a cold plunge, with a goldfish aquarium set into the bath wall. ¥600; a toiletries-and-towel set is sold at the desk. Ideal before a flight or after a late arrival. Tattoos are fine, as in most sento.
About 80 minutes from Ikebukuro by Laview limited express, a complex hot-spring facility joined to Seibu-Chichibu Station. Themed on the 300-plus festivals Chichibu holds each year, it packs 9–10 tubs per side including open-air baths, a high-concentration carbonated bath and saunas. The food court serves waraji katsu-don and Chichibu soba; the shop sells local sake and miso pickles. ¥1,100 on weekdays, 10:00–22:00; morning baths from 6:00 on weekends.
About 70 minutes from central Tokyo via the Aqua-Line, a hot-spring inn founded in 1950 on the shore of Lake Kameyama in the Boso hills.

Day use 11:30–18:00, ¥1,000 on weekdays; no day bathing Thursdays and Fridays. In autumn pair it with a foliage cruise on the lake.
A day spa on the Hinosawa stream in Oku-Nagatoro, named after Suisen-ji, the final temple of the Chichibu 34 Kannon pilgrimage. Mangan Falls tumbles right in front of the open-air bath—stunning in fresh green and autumn colour. pH 9.4 alkaline water with a pronounced silky feel. ¥980 weekdays (¥750 after 17:00), ¥1,200 weekends. Combine with the Nagatoro river boats or Mt. Hodo.
One of the Bōsō peninsula's largest spa resorts, in Shirako on Kujūkuri Beach. Soak in iodine-rich, tea-coloured Chōsei spring water in the open-air bath, with seven rock-bath rooms, saunas, nap lounges, banquet halls and lodging on site. Open straight through from 10:00 to 08:00 the next morning; stays past 01:00 incur a late surcharge. Free shuttle from JR Mobara Station (reservation required). ¥1,600 weekdays, ¥1,900 weekends. Tattoos—including stickers and paint—are strictly refused.
A 12-room inn in Yoro Valley, the Boso Peninsula's autumn-colour spot and the last place in the Kanto region to turn, peaking late November to early December. Boso's signature coffee-coloured alkaline 'black water' fills the indoor and open-air baths; day use is a flat ¥700 for ages 3 and up, 11:00–15:00. Eat lunch in the dining room and the bath is free — spring bamboo-shoot dishes are the speciality. Five minutes by bus from Yoro-Keikoku Station on the Kominato Railway to Yorokan-mae. Lunchtime opening can be suspended at short notice, so phone ahead.
A super-sento 15 minutes by car from Kawagoe's 'Little Edo' warehouse streets, where brown natural spring water pumped from 1,200 m flows freely through both indoor and outdoor tubs. Nine baths per side plus two saunas, a carbonated bath and the signature 'Zabūn' water feature; the Zabūn and Sarasara wings swap between men and women on odd and even days. ¥900 weekdays, ¥1,000 weekends, ¥100 off 8–9 am and after 22:00. Open 8:00–25:00 every day with 200 parking spaces — a proper onsen near Tokyo to end a Kawagoe day.
A natural-spring super-sentō on the 5th–6th floors of the building linked by footbridge to the north exit of Kabe Station on the JR Ōme Line. The alkaline simple spring from 1,500 m down is known for leaving skin silky; the top floor has an open-air bath, lying bath, hot sauna and cold plunge plus an outdoor rest deck facing the Tama hills. Open 10:00–23:30 (last entry 23:00); ¥1,000 weekdays, ¥1,150 weekends, cheaper after 21:00. The Baijuan restaurant's weekday lunch-and-bath set is good value. The most convenient day onsen in western Tokyo — stop off on the way back to Shinjuku after hiking Mt Mitake, driving Okutama or browsing Ōme's retro shopping street. Closed the third Wednesday.
A quiet bath-only annex within the Tenzan Tōjikyō grounds along the Sukumo River, up the valley from Hakone-Yumoto. Where neighbouring 'Higana Tōji Tenzan' is a full-day complex with lounges and dining, Ikkyū has no indoor bath at all — just open-air tubs of wood and stone fed free-flowing by two springs, a sodium-chloride and an alkaline simple spring. Silver-ion sterilisation (no chlorine smell), spare design and a hushed, no-chatter atmosphere keep regulars loyal. ¥1,200; open 11:00–20:00 (until 21:00 weekends and holidays, last entry one hour before), closed Thursdays. On weekdays a ¥300 'hashigo' ticket lets you add Tenzan next door. About 5 minutes from Hakone-Yumoto Station by the inns' shuttle bus or taxi, or a 25-minute walk.
Five minutes on foot from Musashi-Koyama Station on the Tōkyū Meguro line, this rare central-Tokyo bathhouse offers two different natural hot springs. The indoor bath is coffee-coloured 'kuroyu' (sodium-bicarbonate water); the open-air bath uses salty rust-brown 'golden water' pumped from 1,500 m below and left free-flowing — both certified as therapeutic springs. Admission is Tokyo's standard sentō rate of ¥550, with sauna and bedrock bath extra. Open 12:00–24:00, from 08:00 on Sundays; closed Mondays (open if a holiday). Close to Meguro and Gotanda, it pairs perfectly with snacking along the Palm shopping arcade. Soap and shampoo provided.
A hot-spring hotel on the cliffs of Inubōsaki, the easternmost point of the Kantō region. Perched on a cape jutting into the Pacific, its rock rotenburo and European-style open-air bath 'Opia' look out to the horizon and the Inubōsaki lighthouse; on New Year's Day you can watch Japan's earliest sunrise from the tub. The day-use course runs 12:00–19:00 (leave by 20:00), ¥1,500 for a 90-minute stay including bath towel, face towel and toiletries, so come empty-handed. Open daily (special pricing at Obon and New Year). Seven minutes on foot from Inubō Station on the Chōshi Electric Railway; combine with a seafood lunch in Chōshi and the 'Hill Where the Earth Looks Round' observatory.
One of the largest spa complexes in Saitama, in Kumagaya in the north of the prefecture. Its own alkaline simple spring, pumped from 1,500 m at over 600 litres a minute, feeds a wide range of tubs — a free-flowing open-air 'raw source' bath, pot baths, lie-down baths and a high-concentration carbonated bath. There is a löyly sauna, cold plunge and a garden-view outdoor rest deck. The optional 'Onkatsu Café Nest' adds eight kinds of bedrock-bath rooms, manga and free drinks for an all-day stay.

A natural hot spring to visit after strolling Kawagoe's 'Little Edo' warehouse street. Its own sodium-chloride spring from 1,200 m fills indoor and open-air baths in two zones, 'Wood' and 'Stone', which swap between men and women daily. Nine baths and three saunas in all — a carbonated bath made by dissolving CO₂ into the spring water, a free-flowing source bath, bedrock-bath rooms and a private family bath — make for an in-house bath-hopping course. Adults ¥850 on weekdays, ¥950 on weekends and holidays; open 10:00–24:00 (from 09:00 on weekends and holidays, last entry 23:00), no regular closing day apart from maintenance.

Seibu bus from Hon-Kawagoe Station (Seibu Shinjuku Line) to the 'Hōmukyoku' stop; 150 free parking spaces.
A big spa resort on the cliffs of Cape Inubō, the first place on Honshū to see the New Year sunrise. The panoramic 'Ichibō-no-yu' main bath sweeps 180 degrees across the Pacific, and with the open-air bath, bedrock-bath rooms and sauna you can watch the sun climb out of the horizon or gaze at Inubōsaki lighthouse while soaking. The water is the sodium-chloride Byōbugaura spring. Adults ¥1,500 on weekdays, ¥1,700 on weekends, holidays and high season (cheaper for morning baths and after 17:00); open 10:00–23:00 (last entry 22:00), and on Saturdays you can stay through to 08:00 the next morning; open every day. Restaurants, banquet rooms, relaxation treatments and an ocean terrace make it a full-day stop to pair with the Chōshi Electric Railway, wet rice crackers and seafood. About 10 minutes on foot from Inubō Station; about an hour by car from Itako IC.
A hideaway day spa in a copse of trees near Jindaiji, Tokyo's second-oldest temple, and its soba-shop village. The blackish-brown 'kuroyu' sodium-chloride water from 1,500 m carries compounds from ancient plant matter, feels viscous on the skin and keeps you warm long after. The wooden bathhouse holds an indoor bath, a rock open-air bath, sauna and cold plunge, and an outdoor rest deck among seasonal greenery — more like a country inn than a big spa complex. Adults ¥1,080 on weekdays, ¥1,180 on weekends and holidays, with cheaper 30-minute and one-hour tickets. Open 10:00–22:00 (last entry 21:00), every day apart from inspection closures. A soba restaurant and rest room are on site — a fine finish to Jindaiji temple and the Jindai Botanical Garden. Free shuttle buses from Chōfu and Tsutsujigaoka stations.
A natural-spring bath complex about 5 minutes on foot from Minami-Tama Station (JR Nambu Line) in Inagi, amid the greenery of the Tama hills. The mildly alkaline water from 1,700 m down is pale amber and soft on the skin; the outdoor area has a free-flowing rock bath, pot baths, lie-down baths, a carbonated bath and seasonal specials, while indoors are a high-concentration carbonated bath, jet baths, a sauna with löyly sessions and a cold plunge. With more room than central-Tokyo spas, its outdoor rest deck among trees is a real draw. Entry: adults ¥1,000 on weekdays, ¥1,200 on weekends and holidays; children ¥520/¥680; bedrock baths extra (¥750 on weekdays). Open 09:00–01:00 on weekdays and 07:00–01:00 on weekends and holidays (last entry midnight). Closed only on the third Tuesday of March, June, September and December. Restaurant, body care and a manga corner on site. About 40 minutes from Shinjuku via the Keiō and Nambu lines, easy to pair with Yomiuriland or a walk in the Tama hills.
A natural-spring bath complex on a wooded Musashino plot in Saitama's Nishi ward. The source, over 600 litres a minute from 1,500 m down, is a faintly green-tinged amber sodium-chloride water; in the outdoor area the rock bath and 'source tepid bath' are filled free-flowing without heating or dilution, and the place is famous among enthusiasts for its 'nuru-yu culture' of long soaks at around 38 °C. There are also raw-source pot baths, lie-down baths, a high-concentration carbonated bath, a sauna with löyly and a deep cold plunge, and an outdoor rest area facing the trees — remarkably quiet for the suburbs. Adults ¥880 on weekdays, ¥980 on weekends and holidays; children ¥500/¥550; open 10:00–24:00 (last entry 23:30), irregular closures. Restaurant, body care and scrub treatments on site.

The Umi no Kairō bathhouse of this large resort hotel on the Pacific shore of Kamogawa, on the outer coast of the Bōsō Peninsula, welcomes day visitors. Fed by Kamogawa Onsen, tapped in 2003, its open-air bath faces the ocean with an uninterrupted view of the horizon and breaking waves; there are also an indoor bath, sauna and a glass-walled lounge looking out to sea. Adults (junior-high age and up) pay ¥1,650 and children aged 3–12 ¥825, rising to ¥1,760/¥880 in peak periods such as Golden Week, summer and New Year.

Open every day, with entry limits when crowded, and day plans with spa treatments or lunch are available. About 5 minutes by shuttle or car from Awa-Kamogawa Station on the JR Sotobō Line, close to Kamogawa Sea World – a fine finish to a day at the beach.
An urban natural hot spring 8 minutes on foot from JR Sugamo Station, named after Somei village, birthplace of the Somei-Yoshino cherry. Renovated in August 2025, the interior is now calmer and more Japanese-modern. Amber sodium-chloride strong-salt water pumped from 1,800 m underground holds heat so well it is called the 'bath of warmth', enjoyed in an outdoor rock bath, pot tubs and a garden-view indoor pool, with a hot sauna, cold plunge, outdoor cooling area and a mist sauna on the women's side. Admission including towels and loungewear is ¥2,100 on weekdays and ¥2,900 on weekends and holidays for adults, ¥1,200 for children aged 6 to elementary school – city prices, but with no time limit you can stay all day.

Japanese, Western and Chinese dining, a large tatami rest hall, body care, scrubs, esthetics and even hair styling are on site, and a free shuttle bus runs from Sugamo Station; parking for 88 cars (2 hours free on weekdays). Combine it with Sugamo's Jizō-dōri shopping street or Rikugien garden for the closest thing to an onsen getaway on the Yamanote Line.
