Natural Hot Spring Heiwajima

3.8 (1708)Public BathPoint Of InterestEstablishment

Heiwajima Natural Hot Spring, known locally as Heiwajima Onsen, is a popular bathing facility located in Ota Ward, Tokyo. The hot spring draws its waters from 1,500 meters beneath the earth's surface, bringing up natural sodium chloride waters that are believed to have therapeutic properties. The facility opened in 1983 and has since become a favorite retreat for Tokyo residents seeking relaxation without leaving the metropolitan area.

The hot spring water contains a high concentration of minerals, particularly sodium and chloride, which give it a distinctive golden-brown color. These mineral-rich waters are reputed to help with muscle fatigue, joint pain, and skin conditions. The facility maintains the water at temperatures between 40 to 42 degrees Celsius, providing an authentic onsen experience. What distinguishes Heiwajima from many urban hot springs is that it uses genuine natural spring water rather than heated tap water, making it one of the few authentic hot springs accessible within Tokyo's 23 wards.

Visitors can experience both indoor and outdoor bathing areas, with the outdoor bath offering a rare opportunity to enjoy hot spring bathing under the open sky in central Tokyo. The facility includes several bath types beyond the main hot spring pools, including saunas, cold plunge pools, and jet baths. Traditional Japanese bathing etiquette applies, meaning visitors must wash thoroughly at shower stations before entering any communal bath. The onsen is gender-separated with distinct facilities for men and women.

The complex also features dining options serving Japanese cuisine, relaxation lounges, and massage services. Many visitors spend several hours at the facility, treating it as a comprehensive wellness experience rather than a quick bath. The atmosphere remains distinctly local, attracting neighborhood residents and Japanese tourists more than international visitors.

Heiwajima Onsen is located approximately 15 minutes by foot from Heiwajima Station on the Keikyu Main Line. Alternatively, visitors can take a free shuttle bus that runs from the station to the facility. From central Tokyo stations like Shinagawa, the journey takes roughly 20 minutes by train. The admission fee is approximately 2,500 to 3,000 yen for adults, with additional charges for towel rental and optional services.

What other travelers are saying about Natural Hot Spring Heiwajima

I always stop relaxing at Heiwajima Onsen while a long wait for my next flight. This place is perfect for hanging out if you don’t want to explore downtown. The facility includes shower, onsen, sauna, steam room, restaurant, snack shop, spa for fee, relaxing room and tv room. I landed at Haneda at 6AM and spent 7 hours at the onsen for late afternoon flight. How to get there: Use Keikyu line at the airport (Narita or Shinagawa direction train. Get off at Heiwajima station take about 22 mins for 🚉 279 yen Once get off the station, Make a left turn to bus stop no.3 heading to Big Fun Heiwajima for 100 yen (which is next stop and last stop, so you won’t miss it) You will see Donki, next to it on your left hand side is escalator to the second floor. Here you are in front of the onsen. 7 hours for 2,300 yen (including bath towel, pajama, lockers) oh, btw if you have a big suitcase, free of charge to keep in property. They provide big lockers for big bags but you need to insert 100 yen coin to operate but will return when you retrieve your bag. Total of the trip from Haneda airport to Heiwajima onsen is Train: 279x2 = 558 Bus: 100x1 = 100 (you get a free ride to train station , just ask the staffs for a free bus ticket after check out from the onsen) Entrance fee: 2,300 Total: 3,058 yen BTW, massive tattoo is not allowed in here. small tattoo can be covered by tattoo cover sheet. They also sell on the property for 298 yen/sheet. So buy from somewhere else. Anyway, Much cheaper than staying at hotel. I highly recommend it.

Love the natural onsen. It did make my skin tsurutsuru(smooth and shiny). My friend and I reserved the first time for a Loyly sauna and the experience was pretty great! After pouring an essence like basil and hinoki, the facilitator showed his moves with great technique. Such a vibe!

Nothing beats a soak and a snooze after a grueling day of travel. Heiwajima is a great onsen just a short cab ride away from Haneda Airport. I prefer it to the onsen in the hotel attached to Haneda, as it’s both cheaper and has more features: sauna, hot tub, steam room, relaxation room, diner. I wish they had more shuttle options to/from the airport, but otherwise it’s a perfect spot.

It was great experience! I arrived early flight so I came to the spa. I could rest a little bit, there are enought lounge for all, 3 rooms. It was very refreshing and healing. I felt new! The only thing I didn't like is in the morning the cleaning lady turned on all the light of the lounge and start making lots of noise. The experience was excellent and comparing with another onsens, this one can say, one of the best!

Do you have an extended layover in Tokyo? Then this is a great place to stay and wash up for your overnight needs. After walking around for 2 hours in the Tokyo summer humidity a nice bath felt amazing and relaxing. The water temp is nice and hot. And compared to plane seats, you will get an amazing night sleep in the relaxation lounge (though you might need some ear plugs and an eye mask if you sleep early). Overall solid experience, but kinda sucks that there is nowhere decent nearby to catch the sunrise.
