Tokyo’s top onsen

Where to enjoy a relaxing hot-spring bath – without leaving Tokyo

By Time Out Tokyo Editors

Living in one of the most volcanically active countries in the world can have its perks, not least the abundance of natural hot springs or onsen. Tokyo included, the Nippon Onsen Research Association counts over 3,000 onsen spread around Japan, in locations ranging from Hokkaido to the southernmost islands of Okinawa. Traditionally, the citizens of Edo had to trek to spa towns like Hakone and Atami if they wanted to get their fix, but today's Tokyoites have it easier: they just drill a few kilometres underground to tap their own source of geothermal goodness. You can now find a diverse range of onsen in Tokyo, from old-school public baths that are practically indistinguishable from your average (or not so average) sento, to massive, theme park-style complexes such as Oedo Onsen Monogatari. There's never been a better time to check out some of Tokyo's best hot-spring baths – and we've got something for every taste and budget right here...

North Tokyo

Niwa no Yu

Health and beauty Spas Nerima

Don't let the fact that it's located next to the dreary Toshimaen amusement park put you off: this is the nicest of Tokyo's mega-onsen bathing complexes. Housed in a Japanese garden designed by leading landscape architect Kenzo Kosugi, Niwa no Yu is divided into male and female onsen bathing areas, with a central pool, outdoor jacuzzis and Finnish-style sauna where couples can hang out together (bathing suits required, natch).

Tokyo Somei Onsen Sakura

Health and beauty Spas Sugamo

Though it's best visited during cherry blossom season, when the somei-yoshino trees on the premises are at their finest, this onsen bathhouse has enough going for it to be worth a look any time of year. The sodium chloride-rich waters may not be much different to what you'd find at many other baths in the city, but at Sakura they're filtered to remove the colour and smell.


Spa LaQua

Health and beauty Spas Suidobashi

More like a 'super sento' than a traditional onsen, this sprawling complex inside Tokyo Dome City boasts a dizzying array of facilities: once you've finished soaking in the open-air rotenburo and bubbly massage baths, you can go and sample one of the multitude of beauty treatments on offer, or check out the high-tech saunas in the separate Healing Baden zone. Open all night.

Times Spa Resta

Health and beauty Spas Ikebukuro

One of the classiest spa complexes town, Spa Resta occupies an unlikely location: floors 10 to 12 of the Times Station parking garage and car rental facility in Ikebukuro. Don't let that get in your way though, as this spot is perfect for a long, lazy day of soaking, eating and relaxing. The men's side has a wide range of baths, a Finnish-style sauna, rotenburo and even a terrace area with deck chairs, while women can look forward to an open-air jacuzzi, a 'clear mist' sauna complete with refreshing aroma, and other beauty-enhancing facilities.


Fuku no Yu

Health and beauty Saunas and baths Sendagi

Looking more like a resort-style ryokan than an old-school neighbourhood bathhouse, Fuku no Yu sure stands out in quiet Komagome. Its twin sides, switched up every week, are both dominated by newly painted depictions of Mount Fuji – the more orthodox one by veteran sento artist Kiyoto Maruyama, the other, bold and blood-red, by fellow specialist painter Morio Nakajima.

Yama no yu Onsen

Things to do Toshima

A retro public bath from the mid-Showa period, Yama no yu Onsen looks the same as when it opened in 1960 and is undoubtedly one of the most picturesque sento we’ve been to. The round bath in the middle of the room is an unusual feature. It’s divided into two parts – one a jet massage bath and the other an aroma bath that changes its scent every day. The steam sauna room with wormwood aroma is excellent for your skin and can be used at no extra charge.


Saya no Yudokoro

Health and beauty Spas Itabashi

Fed from a natural hot spring 1,500m under ground, the water at Itabashi's top onsen facility is rich in sodium chloride, giving it a characteristic greenish-brown colour. But this health-bringing elixir isn't the only thing worth noting at Saya no Yudokoro: its renovated, traditional-style buildings and zen garden are gorgeous, as is the rotenburo, which is surrounded by lush greenery.


Health and beauty Saunas and baths Nerima

Sento in Tokyo are famed for their Mt Fuji murals, but at this one you can also enjoy a projection mapping display while you soak in the natural hot spring. An outdoor bath and sauna are also available. 


Hot Land Midoriyu

Health and beauty Akabane

Midoriyu is the largest sento in the Akabane area and boasts a predictably plentiful selection of baths, including ones with herbal aroma, several open-air baths, jacuzzis and a sauna. Also equipped with a spacious hall where you can down a beer and some snacks after your soak, it's popular among joggers running along the nearby Arakawa.

East Tokyo


Health and beauty Spas Ryogoku

The atmosphere of Tokyo's traditional shitamachi (downtown) area lives on at this compact onsen bathhouse, a brisk ten-minute walk from Kinshicho Station. They've managed to cram a lot into the bathing area ('cosy' would be an understatement), where the tubs range in temperature from chilly to a scalding heat that's likely to appeal most to wizened old gits with skin like leather.


Health and beauty Saunas and baths Asakusa

Though it's located right in the centre of Asakusa, Jakotsuyu tends not to get much tourist traffic – which is all the more surprising when you consider that it's been going since the Edo period. The owners have given the place a few overhauls since then, and hardcore shitamachi geeks may be disappointed by the functional, modern interior.


Myojin no Yu

Health and beauty Spas Adachi

Whatever your ailment, it can probably be treated at Myojin no Yu, an attractive, traditionally styled bathhouse whose salty, iron-rich netsu no yu (literally, hot waters) are believed to improve circulation and offer relief for neuralgia, muscle pain, sore joints, sensitivity to cold and just about any other complaint you care to mention.

Kodai no Yu

Health and beauty Spas Shin-Koiwa

It's a bit of a hike to get there, but this functionally decorated onsen complex in Shin-Koiwa is one of Tokyo's biggest, not to mention one of the few that stays open all night long. The facilities at the three-floor Kodai no Yu include outdoor rotenburo and hinoki cypress tubs, as well as family rooms that can be rented out.


Rakutenchi Spa

Health and beauty Spas Kinshicho

Up on the ninth floor of the Rakutenchi entertainment complex in Kinshicho, this 24-hour, men-only spa seems aimed mainly at office workers who've missed their last train home. There's an onsen bath and a pair of saunas, plus three relaxation rooms equipped with reclining chairs – the quietest of which comes with an optional wake-up call from the staff.


Health and beauty Spas Kita-Senju

This majestic, temple-like building is one of the most attractive sento in eastern Tokyo. Cleaner than most of its peers and boasting its own rotenburo, it also has cold beer in stock.



Health and beauty Spas Nippori

Its tiled roof and imposing entrance immediately distinguish this classic bathhouse from your average neighbourhood sento. In business since 1916, Teikoku-yu boasts one of the most beautiful buildings of any traditional bathhouse in the capital – the high ceiling, lush garden with its koi carp, and powerful Mount Fuji mural are all worth a closer look. This is far from the cleanest or most comfortable sento in the area, but it deserves a visit for its historical value alone.

Central Tokyo

Oedo Onsen Monogatari

Health and beauty Spas Aomi

In addition to housing natural hot spring baths, open-air baths, saunas and more, this Edo-era onsen theme park also does a line in festivals, fortune telling, places to drink and dine, shopping, and even overnight accommodation. It's particularly worth visiting at the moment, as the prices are currently lower than usual.

Take no Yu

Health and beauty Spas Azabu-Juban

A 2011 renovation at this long-running Azabu-Juban bathhouse brought Take no Yu into the modern era, just shy of its centennial. The chief attraction here is the mineral-rich, black-brown onsen water, which is so prized that customers can even pay ¥20 per litre to bottle the stuff up and take it home.

新宿天然温泉 テルマー湯
新宿天然温泉 テルマー湯


Health and beauty Spas Shinjuku

This impressive-looking spa complex was inspired by the popular Thermae Romae series of manga and movies. Open 22 hours every day, Thermae-Yu features hot spring baths and rotenburo – supplied with onsen water from Izu daily – stone saunas, a full-on beauty salon, scrub treatments and a lounge complete with a café, bar and restaurant.


Health and beauty Spas Yoyogi-Uehara

Antique pictures and celebrity autographs line the walls from entrance to locker rooms and the whole place is filled with objects and souvenirs collected by the owner, making the Daikoku-yu bathhouse feel almost like a museum. There's a comfortable massage bath, cold water bath, steam bath, electric bath and sauna, while the men’s sauna features a spacious rest room with relaxation chairs.



Things to do Iidabashi

See Mt Fuji without leaving downtown Tokyo – simply visit this old-fashioned sento, where one entire wall is given over to a mural of the mountain.


Things to do Ginza

This bathhouse first opened in Ginza in 1863, during the dying days of the Edo period, and it hasn't made much effort to update its retro stylings since. There's an old-fashioned reception desk on the way in, and an impressive mural of Kutani porcelain tiles depicting carp, spring and autumn flowers and birds that you can enjoy while soaking in the tub. There are two baths, one pleasantly warm and the other heated to a fairly toasty 42° C.



Health and beauty Spas Nakameguro

A designer sento overhauled by architect Kentaro Imai, Kohmeisen reopened in 2014 in the heart of Nakameguro’s trendy shopping area. There are three baths – massage, carbonated and cold water – and a sauna. A rotenburo is available on only one side of the sento, so the men’s and women’s sides are swapped every Friday to allow everyone to experience rooftop bathing – a rare treat in central Tokyo.

West Tokyo

武蔵野温泉 なごみの湯
武蔵野温泉 なごみの湯

Nagomi no Yu

Health and beauty Spas Ogikubo

There aren't many Tokyo spas with a location as convenient as this, right outside the west exit of Ogikubo Station. Only the outdoor rotenburo at Nagomi no Yu use hot-spring water, but there's a range of other baths and saunas too. If you want to go all-out with the pampering, it's worth paying an extra ¥300 to get access to the various stone saunas and 'healing' zones, on the third and fifth floors.

The Spa Seijo

Health and beauty Spas Chitose-Funabashi

Squeezed between a fitness club upstairs and a branch of Uniqlo on the ground floor, this spa complex draws hot spring water from 1,200 metres underground to supply its indoor and outdoor baths. The Spa Seijo also has a range of beauty treatments on offer, from pedicures to Ayurveda massages.


Utsukushi no Yu

Health and beauty Spas Takaido

While most of Tokyo's inner-city onsen are either glorified sento or pricey theme parks, Utsukushi no Yu is a real gem, offering attractive outdoor rotenburo and a range of indoor tubs and saunas for under ¥1,000. Located in the western neighbourhood of Takaido, the complex is run by a local swimming club, and at weekends bathers are also given free run of the 25m indoor pool (hence the higher price).

Jomon no Yu

Health and beauty Spas Fuchu

This Fuchu spa complex was the priciest onsen in all of Tokyo when it first opened in 2006, charging bathers a gobsmacking ¥4,300 for a dip, though the admission fees have since been reduced to (slightly) more sensible levels since then. Expensiveness breeds exclusivity, of course, and you won't have to jostle people aside for a space in the baths here.



Health and beauty Spas Sasazuka

While other onsen in Tokyo are inclined to be conservative with their precious hot spring water, that isn't the case at this dowdy public bath. Even the taps and showers at Sakaeyu dispense pure onsen water – a generous profligacy that goes some way to compensating for the cramped dinginess of the place.



Things to do Koenji

Throw off your inhibitions and bathe with the regulars at this wonderfully old-school Koenji sento featuring an impressive menu of soaking options, including a scented bath and a milk bath. If the water feels a tad hot, try concentrating on the majestic Mt Fuji murals decorating both the men's and women's sections.


Yukemuri no Sato

Health and beauty Spas Sengawa

A so-called 'super sento', Yukemuri no Sato is located in Chofu and features a whopping 12 different types of baths including a whirpool bath, rotenburo and Japan's first electric bath filled with carbonated spring water. Try out the popular Surga bedrock bath (at an additional cost) or take a nap on the heated floor while reading manga.

Ofuro no Osama Hanakoganei

Health and beauty Saunas and baths Tama area

16 baths and saunas of all sizes, including seven with natural onsen water, await at the Hanakoganei outpost of Ofuro no Osama. Part of a Kanto-wide chain of 'super sento', this one can be enjoyed for a mere ¥880 on weekdays – as long as you sign up for their membership system. The open-air area features a hot stone bath where you can lie down and look up at the stars while warm water runs down your back.

South Tokyo

Nu Land Sagami-yu

Health and beauty Spas Kamata

Sitting not far from the border with Kanagawa prefecture, this Zoshiki bathhouse boasts a restaurant, karaoke room, massage service, relaxation chairs and small rooftop garden. If you're just looking to take a long soak, there's a range of tubs to choose from, including a rotenburo and an indoor onsen bath that uses Ota-ku's distinctive black kuroyu water.

Heiwajima Natural Hot Spring

Health and beauty Spas Heiwajima

In a savvy move, this 24-hour bathhouse has started offering a free shuttle bus service to nearby Haneda Airport every morning – perfect if you've got an early flight and would rather wait in a hottub than the departure lobby. The baths at Heiwajima Natural Hot Spring are designed to treat a range of ailments, from insomnia to lower back pain, and – as the name suggests – all of them use bona fide onsen water.



Health and beauty Spas Musashi-Koyama

Get the full onsen experience at sento prices in this neighbourhood bathhouse in southwest Tokyo. Shimizuyu used to offer only the inky black kuroyu water that's typical in this part of the city, but they tapped into a deeper spring during an extensive overhaul in 2007, meaning that you can now also bathe in iron-rich 'gold' water in the outdoor rotenburo.

Togoshi Ginza Onsen

Health and beauty Spas Togoshi-Ginza

This modern-looking bathhouse is actually the reincarnation of a 40-year-old sento that closed its doors in 2006. Reborn as Togoshi Ginza Onsen, it now has a few baths supplied with authentic hot-spring water, as well as boasting a unique wall mural that blends a traditional depiction of Mt Fuji (by veteran sento artist Morio Nakajima) with a garishly modern rendering of the same peak.


Teru no Yu

Health and beauty Spas Ota

Housed next to a laundromat on the ground floor of an apartment building, the Teru no Yu bathhouse couldn't look much shabbier from the outside. The inside isn't much better, either, although your money goes a long way here: the indoor bathtubs include one fashioned from cypress wood, and there's also a small rotenburo.

Kamata Onsen

Health and beauty Saunas and baths Kamata

This old-school bathhouse's rare black hot spring is said to heal back pain and give you healthy skin. In addition to that quirky speciality, you can experience all kinds of baths here, from high and low temperature ones to bubble and electrical baths, while the facility also houses a sauna. Head to the second floor and enjoy karaoke while grabbing some food and drinks.



Health and beauty Ikegami

Located in a quiet residental area, this sento has been in operation since 1959, although its present incarnation is the result of much renovation and rebuilding. In spring, the main attraction is the view of the cherry blossoms, which can be admired even while you're soaking away. The dark-coloured water used is the same as at many sento in southern Tokyo, known as kuroyu.


Things to do Ota

Opened 60 years ago and recently renovated, Kugahara-yu features a majestic Mt Fuji mosaic on its bathroom walls. The men’s and women’s sides are decorated with different colour schemes (representing the moon and the sun), but you’ll get a chance to experience both as they rotate the changing rooms every two weeks. Regardless of the less than convenient location, it's usually packed with families and kids.


Spa & Hotel Nagomi

Health and beauty Kamata

It's all natural, skin-friendly onsen water at this fancy Kamata spa, which boasts a women-only hot stone sauna area, regular saunas for both men and women, and a combined restaurant and 'relaxation area'. If you don't feel like lingering, consider opting for a one-hour 'speed' ticket (¥1,250 on weekdays, ¥1,550 on weekends and holidays).

Out of town

Roten Garden

Health and beauty Spas Machida

Convenient it ain't, but this onsen complex on the outskirts of Tokyo offers attractive rotenburo baths, indoor tubs and saunas at a fair price. Roten Garden bills itself as Machida's first authentic onsen, drawing its sodium- and chloride-rich hot-spring water – said to be good for muscle pain and achy joints – from a depth of nearly 1,400m underground.

Moegi no Yu

Health and beauty Spas Tama area

10 minutes' walk from Okutama Station on the JR Ome line, this onsen offers some welcome respite after a day spent hiking in the local mountains. The facilities include indoor and outdoor rotenburo baths, as well as a communal foot bath – though remember to bring your own towel, as it isn't included in the price.


Tsurutsuru no Yu

Health and beauty Spas Tama area

Its location at the end of the hiking trail from Mt Hinode has made this onsen a popular stop for local ramblers, and you can expect it to get fairly busy on weekends and national holidays. Depending on which day you visit, male and female bathers will be assigned either to the traditional Japanese-style baths or a more ersatz 'Western' selection of tubs, all of which use alkaline hot spring waters drawn from 1,500m underground.

Kazuma no Yu

Health and beauty Spas Tama area

An hour's bus ride from the nearest train station, on the border between Tokyo and Yamanashi prefecture, Kazuma no Yu is likely to appeal most to hikers exploring the local trails. The facilities certainly don't merit a special trip, but the alkaline hot-spring waters should provide relief to aching limbs (not to mention a bewildering list of other ailments).


Ume no Yu

Health and beauty Ome

Directly connected to Kabe Station out in the western wilds of Ome, Ume no Yu is great for washing off the dirt after a long hiking trip in the mountains. They've got a nice selection of open-air onsen baths, plus two saunas and a very good Japanese restaurant – the soba and udon are particularly great value.


Health and beauty Saunas and baths Machida

Sento architect Kentaro Imai’s newest creation was completed in late 2016 way out west in Machida. Aiming to stem the flow of customers leaving Okurayu for the new ’super sento’ opened nearby, the owner hired Imai to freshen up his traditional bathhouse. The architect’s response was to cut down on, well, everything – an approach that resulted in what could be Tokyo’s most minimalist onsen.


Yunohama Open-Air Bath

Things to do

Located on Niijima, part of the Izu island chain, this open-air bath is themed on the ruins of ancient Rome – for some inexplicable reason. Enjoy mixed bathing in six different hot springs, open around the clock and boasting grand views of the starry sky at night. Best of all, the facility is completely free for all comers.
