Thermae-Yu

This place is an amazing find at the heart of Shinjuku! Thanks to our friend who recommended this relaxing place Water: Perfect temp, silky smooth, and that subtle mineral smell—so relaxing! Baths: Awesome variety, loved the outdoor one with the sky view. Super clean everywhere too. Saunas: (with additional 900 yen charge) there’s a variety of sauna. Relaxing and aromatic everywhere. I love this area 🥹 Amenities: They had everything, even fancy teas in the lounge. So comfy! Atmosphere: Chill and peaceful vibes. Not crowded at all, everyone was respectful. Experience: Staff was super nice, location was beautiful. Totally worth it, can't wait to go back!

Okay, this onsen is EVERYTHING! They have all these different pools, each with a special type of water that does cool stuff for your body. One was super warm and made my muscles feel like jelly (in the best way!), and another one had this silky texture that left my skin so soft. And there’s even a cold plunge if you’re feeling brave, it’s like an instant energy boost! The best part? They’re totally chill with small tattoos, so you don’t have to worry about covering up. And you don’t need a reservation, which is awesome. You just show up and dive right into the relaxation zone. I’m already planning my next trip back because, honestly, it was that good!

High standing luxurious onsen open 24h/7. One of the best onsen I tried in Tokyo, located in the center of tokyo near the Shinjuku train station, very accessible and cheaper than french sauna in Paris. Expensive compared to local onsen but very clean, many services included and many baths with different properties such as magnesium enriched baths, pink coral light bath, clay in the sauna and salt for exfoliation. Beware of the onsen tax that is not included in the price shown online. They are additional charges when you exceed midnight (you pay when you check out) and even more charges if cumulated with weekend or national holidays. I didn’t get to try the food nor the floor dedicated to sauna/massage or the massage chairs located downstairs because all those services were closed at midnight. For 2 hours onsen, during the weekend (+750 yen) and after midnight (+2300 yen) I paid 6000 yen (approximately 35€), meaning twice the price if I went on a weekday before midnight (2900 yen + 150 yen of onsen tax). Be careful with hidden fees, don’t expect to pay the price shown. You will probably pay more than you think. After the additional fees keep in mind that you have an additional tax computed on top of overall.

Inside the heart of Shinjuku, enjoyed different hot springs, showers and even food. They also offer body massage. Standard entry just 3,000 yen. We loved it after a full day trip.

If you are public bath or even public bath beginner you will loove it. It’s true that the entrance is pricey compared to normal bath (this one is 2700 and the normal one just hundred), buut, they have more than 4th floors to explore, the bath itself is spacious. There are various kind of bath type and water, hot, cold, jacuzzi, open air, etc. Also they have plenty sofas to rest. They also have several types of hot rock spa (I suggest you to take it, ¥900 and its worth it!). And massage (also very good massage, i did the combine 50 minutes and love it!). The entrance fee is including towel, hair brush, so on. My highlight is they are open 24h with convenient sleeping area (some services are not open 24h such as resto), so you can stay overnight (they only charge ¥2,000 for 00:00-09:00), the speedy wifi aand the coworking space!!! The staffs are friendly, clean and not far from the metro station! Strongly recommended!

This was a great bath house. It is more like an elegant bath house because of all of the commodities they provided. The check in is very easy, even though they spoke very little English. Patrons have to wear robes or pijamas type of uniforms, but they have multiple sizes, so no problem for thicker people. The lockers are clean and very helpful to keep all of your stuff. Everything is done with a wrist key where you can lock and unclock your lockers, request extra treatments like the sauna with rocks, or even pay for food. The wrist lock is like a digital key. Every floor has a different level of care. The first floor is to get robes or pajamas, bathrooms, lockers, nap chairs, and a grooming room. The second has the bathhouse with so many different hot pools. Hot sauna, showers, and massage rooms. While the third had the resting loungers, the nail and hair salon. The fourth floor had the hot mats, and the basement has the restaurants. The prices are affordable and the place is extremely clean. We felt relaxed and pampered. We went back three times, and loved every minute of it.

Super nice Onsen facility, huge & clean, offers English language service. Staffs are pro & friendly. Highly recommend the indoor CO2 pool & outdoor natural spring pool, after one week of daily onsen use, my skin became smoother after snorkeling in seawater for 2 weeks that my skin got coarse & had goose bumps like pores, now completely improved & got silky skin! Wow! Also very relaxing to chill in cold weather to cool down after hot spring heat up the body, it has that tipsy feeling which is very nice, warmed up knees also feels nice in winter after long walk touring the city.

I haven't been to other spas in Japan so I don't have a baseline to compare it against. With that said, we had a really good time. The bath and sauna area fits about 150 people and it's gender segregated. There are a lot of different pool options, one sauna and one steam room. Everything was clean and it wasn't too busy when we went on a Tuesday afternoon. They also have a relaxation area which is surprisingly comfortable and people stay overnight at an extra charge. They also offer massage services and have a few restaurants; in fact we saw people working on their computer as well thanks to the free wifi. Overall, it was a fantastic experience and we loved the ambiance.

So incredible!!! I saw this on social media and knew I had to make it here. I ended up arriving in the afternoon, and the front desk staff spoke enough english, with the help of cards, to help me get registered. Then I went to get my clothing from the next desk and I decided that I would hit the rooftop gym. There's a full gym! Treadmills, bikes ellipticals, lots of weights. It was me and one other guy working out. Equipment did look weather worn, but didn't bother me. After that, I went and had a snack of edamame and seaweed, then hit up the sauna. It's a little confusing because everything is on different floors, but there are maps and it's fun to explore every floor - there are multiple rest areas for lounging, watching social media on your phone, etc. I could have stayed FOREVER. I definitely would stay overnight another time. It costs less than $20 USD to stay overnight and there are plenty of resting areas. The restaurant was so good too! My favorite bathing areas were the outside pools, including the shallow lie-down area, and these bathtubs.

This wasn't my jam personally. I've never been to something like this and I wouldn't go back. It's such a weird concept to me to have everyone sleeping in the same room. Ppl are coughing, ppl have their alarms going off.. it's not peaceful. It's also SO HOT everywhere in here. It's so stuffy and uncomfortable. If you have tattoos then you have to buy beige stickers to cover them - and make sure you have your passport with you because they don't let you buy the tat covers without your passport. Which I wish we would've known. There's no signs in English anywhere so I wasn't sure of any of the rules or what any bathing tubs are for. I was wearing a bathing suit and then got kicked out for wearing it... I don't speak Japanese--- so how would I know this?! It's a nude spa. They give you clothes to change into when you get there and they'll only give you one large towel. Don't you dare waste that on your spa time because you won't get another. They give you small little tiny face towels for when you shower coming out of the baths. The showers aren't standing up showers either. Everyone sits naked on these little chairs - which is so gross to me. I don't wanna sit naked on some chair that someone else just sat on. It's gross. Again. Not my kind of place. But hey, some people like this stuff ‍

First time trying this place. Front desk staff spoke English and was helpful and friendly. Clean, well maintained facilities. The restaurants' dishes were tasty and reasonably priced. Look for special discounts such as for women on certain days.

It was a rainy morning, and we were already awake from having jet lag. Although this onsen advertises as being open 24/7, we wish we would've known that the massage services and the cafe were open only during certain hours. With that being said, we still ended up enjoying our time in the nap room, the cold and hot springs, and the amenities in the women's locker room. They also give you a wristband which acts dually as your locker key and your card to purchase drinks from the vending machine. We also enjoyed the pajamas. Next time, we'll have to check out the massages and cafe during operating hours.

My Japanese friend invited me to come here to experience the Japanese sauna and cold plunge portion of the spa. After this experience, I went to 5 other spas in 5 different cities, and out of all of them, this was probably top 2 in terms of the fanciest and cleanest. It was also the most expensive spa on the trip at 2700 yen entry fee. The decor is meant to attract more women to this spa, since a lot of sento/sauna places cater to men. Clean, comfortable, and my mom and sister loved it too. They also oddly liked the clothes they provided too. We decided to dine at the restaurant which was slightly more expensive than outside, but overall pretty good. Would recommend!

Maybe my perception of an onsen is an actual geothermal spring. So I thought this had more Jimjilbang vibes. Plus they have the Korean scrubs too. (Helps to know, I've been to Gwangju and Seoul, and from California. I also been to Budapest and to their bathhouses too. So major bathhouse junkie. It's not my fault that World Aquatics keeps putting swim meets in countries with nice bathhouse cultures!) However, unless you paid extra for the sauna area on the 4th floor, then that's where the separation lies, as well as different kind of pools with properties that are different. Despite this, I decided to try it out. I don't recommend coming here any later than 8, to take advantage of some of the amenities. Also, I don't recommend coming here after a night of drinking. (Hot water immersion + alcohol don't mix. They'll warn you at the reception area.) Which is kinda odd to see a bar downstairs with cocktails and a rooftop bar. Hmmm... Ok so pool. Please, please shower before you go in! I did like the sauna that had a clay mask and salt. I used the salt to exfoliate. The outdoor pool is probably my favorite. No, actually it's the carbonated bath. Ah! Hard to choose. I was playing around with the bubbles on my body and going: "so soft!" But I was so hot from the weather and didn't hydrate so I didn't enjoy my first hour. Even the cold bath wasn't helpful. (Too cold for me to do a full plunge, even as a swimmer). So I took a break and got a foot massage. That managed to really get me to relax after walking in a geta, waiting and shopping for 4 hours for a freaking Pokémon. It gave me about 40 minutes to slightly cool my body down so I went to go back into the pools and noticed that I wasn't feeling too hot in any of them. There are also floors for resting and lie flat seats like a plane. I wish they had some massage chairs. (Oops, homesick over a Jimjilbang in Santa Clara, CA!). I don't recommend going: "hahaha, I can cheap out and stay here as a hotel". Sorry y'all, I don't know if there's luggage storage for that. Overall, I say this is a great way to relax. I was about to cry about how homesick I was, but this onsen helped me relax. Oh pro tip, since there are 3 lockers (shoe, locker room and bath), my suggestion is to have your shoe locker key in your locker room locker and then put your locker room key in the bath locker when you are using the baths). In terms of bathhouses (this means overall since I've gone to multiple bathhouses in different countries), this one might be on the top of the list (until I go to a natural onsen that literally is a geothermal hot spring).

This onsen is amazing! I came here and felt so pampered. + B1&2, lounge, bar, restaurants (for co-ed mingling) + 1 Floor check in + 2 Floor spa. I went into the women's spa (duh) and LOVED their outdoor area. Good blend of sitting / standing / lying down spas I love the area, it is located near a lot of 24/7 sushi and bars. Everything is really clean, safe, and super relaxing. Can easily spend the night here unwinding. This onsen is open 24/7 so makes for a great nap cap after a long day. Great beauty products, and super huge lit up mirrors and sit down area to pamper yourself! I came here 3x times during my last trip to Japan!

I didn't even get to stay for a while because of the minor limit. I don't get what is wrong with minors. Totally ruined my day. Don't recommend if you have children

I came here to relax and also to put myself outside of my comfort zone. I will never forget my time at the sento! For those looking for a walkthrough of how to enjoy your time here, I'll make it easy for you. First off, let me just say that this facility is very clean and all the employees were extremely helpful. This is the only spa/sento I've been to, but it won't be the last. When you walk in, you take off your shoes immediately and find a locker to your right. The available ones have a key in them. You're obviously going to want to take the key with you. After that, you go through a gate and pay for whatever it is that you want. I just wanted to experience the sento. It was about 2400 yen, so it was a little bit expensive, but that was ok for me because I am on vacation. The employees speak basic English. I don't speak Japanese and I had no trouble. Next, you go around the corner and there's a second desk where somebody gives you a basket with some common room clothes and a towel. They also give you a wristband that has a sensor in it that is used to open a locker in the locker room. The locker room is on the same floor not far from there. Use the sensor wristband to open your locker. At this point, you're going to want to change into the common room clothing. You wear this in the hallways and until you get to upstairs. Leave the key for the shoe locker, your normal clothes, and any valuables in there. Once on the second floor, you go to the men's spa room and find another locker to use. This locker is where you put the sensor wristband and the common room clothes. Yes, everyone is naked. No, nobody is looking at you. No, you don't need to shave or anything. The key to this locker is waterproof and can be taken into the baths. Don't bring the sensor wristband into the baths. Side note: I'm not sure where you get it, but make sure you have a small towel with you. They give you a towel with the common room clothes, but I'm not sure if it's the same towel that you take into the baths. I made the mistake of going in there without one at first. From there, you're going to want to rinse yourself before heading to the baths. The showers are in the same room as the baths and are through some sliding glass doors. Make sure it's thorough. It's sort of an etiquette thing. Finally, you can enjoy the baths! There's a lot to choose from. I soaked in each one for about 5-10 minutes at a time with cold water bath rinses in between. It was an incredibly relaxing experience, and I would do it again in a heartbeat. They have, as others have said, a normal hot bath, a fizzy carbonated bath, a "silky" bath, a bath where you can lie down, a massage bath, and a cold bath. My favorite was the carbonated bath! If you're ever lost or unsure of how to proceed, just watch to see what the Japanese people are doing and follow suit. Once you're done bathing (be careful not to overheat), you shower again, put your common room clothes back on, grab the sensor wristband, put your towel in the bin, leave the locker key in the locker, head downstairs, get changed into normal clothing, put the common room clothes and bag in bins, pay, turn in the sensor wristband, grab your shoes, and head out! If you want to test your confidence and reward yourself with one of the most relaxing experiences of your life, come here. Worth it.

Thermae-yu hot springs was the perfect ending to a day packed with being on our feet, touring the various sites of Tokyo. This was my first experience in a Japanese hot spring, and I could not imagine a more relaxing 3 hours. I slept like a baby that night. Admission to the pools is roughly 2000 yen plus 800 yen for the hot rock treatment. (My wife did the massage therapy which is comparable in price to massages we've had in the States). I can't recommend this spa enough as a uniquely Japanese experience. Upon entrance, you start by leaving your shoes in a small locker area immediately outside the front door....as no shoes (or tattoos) are allowed in the facility. (They have skin colored patches that you can purchase for 300 yen to cover small tats). Once you check in, they give you a wrist band and "spa wear" for the common areas.....but plan to wear your birthday suit in the pool / shower area. There are changing rooms on the first floor with lockers for your street clothes and any valuables. It is here where you put on your "spa wear" and go upstairs to the pool / shower area...which is on the second floor....the massage and lounge on the third floor...and the hot rock area, cafe and lounge on the fourth floor. There are three different types of hot rock beds, which are designed for lying flat on your back (in your spa wear), and sweat like crazy. Two of the three rooms have different types of rock beds (although they weren't that different). The third has flat tile beds, is a little hotter than the first two, and included bags of scented spices. Your 800 yen has no time limit, but I couldn't do more than 5-10 minutes in each with nice breaks in between. They also provide a change of spa wear, since mine was sopping wet at the end of the experience. From there, I went down to the pool / spa area for further relaxation and a shower. The pool / shower area includes a salt steam room, a sauna and at least 6 different kinds of pools. These include sit down pools, lie down pools, hot pools, pools with carbonated water, pools with soothing silk, and of course pools with ice cold water. The pool area is all same sex, and entirely in the nude. After the hot rocks, the hot pools made me feel like I was lighter than air. All the stiffness and little aches and pains from walking around for the past 4 days was relieved. The salt steam and sauna, followed by a 2 minute sip in the ice water...made me a true believer. The shower area includes soaps, conditioners, shampoos, shaving cream and razors....so when I was done, it was kind of a bummer getting into my street clothes....but none-the-less, I was a new man....looking forward to my next experience. If it wasn't our last day, in Tokyo, I'd go back every night to end my day.

For my first time at a Japanese spa, this was a top-notch experience. Clean and luxurious. I loved it so much that I went 3 times in my one week in Shinjuku. I ended up specifically traveling to the suburbs to try two other onsens. They were different (I.e. fall foliage and pot-shaped individual baths), and I still liked them, but Thermae-Yu was my favorite, even though it cost more than two and three times than the others. Makes sense, though, because Thermae-Yu provides everything for before (towels, shampoo, conditioner, body & facial cleanser - even hair ties!) and after (moisturizer, brushes, curling iron, flat iron). All I needed to bring was a change of clothes and makeup to go straight out to meet a friend for drinks (instead of going back to hotel to get ready). Next time I'm in Tokyo, it would be hard not to stay within walking distance again, just for this place.

I recently visited this sento with two friends. It is clean, professional, relaxing, and a wonderful sento experience. From what it says, they actually truck in water from a hot springs for you to enjoy the mountain water experience in the middle of busy-busy Tokyo. After enjoying all of the various pools, as well as the sauna and steam room, feeling so clean and happy, we went to one of the two restaurants in the building. There were two choices of restaurants, and we tried the Japanese one. The food was excellent, the service efficient and friendly, and all in all a fantastic experience. I would highly recommend this place to visit. If you spend an hour or two here, you will leave feeling rejuvenated.

This onsen isn't bad but I've definitely been to better. The lounge area is pretty nice and they have sizable baths. Everything was clean and nice enough. There were salt face scrubs in the sauna and that was nice. It's a bit expensive but if you're staying in Shinjuku, you're probably paying for the convenience. If you're able and up to it, I recommend going to an onsen not in Shinjuku. The staff in Shinjuku speak a bit of English but the experience will probably be better at a less crowded, less expensive onsen.

I'm a big fan of Korean-type spas/bathhouses back home, so I wanted to try a Japanese one. This one is in the heart of Shinjuku and very easily accessible. It's also the most reasonably priced and the fanciest sauna/spa/bathhouse I've ever visited. I spent about 4 hours here and all my worries melted away. I especially liked the outdoor hot pools because the cool November air helped when I got a bit overheated. It's also a unique experience to get in a very hot pool with the cool air making steam rise off the water. Definitely recommend!

Wonderful spa to relax on the weekend. I ended up spending several hours here to unwind. Highly recommended!

Really relaxing place in the middle of the city, especially for a busy traveler. Best shower of my life and you can stay overnight instead of getting a hostel. Amazing.

Went a 9:30 am, the baths open from 10 am so I spent time in the relaxation lounge. There were a few people that were sleeping I think from the night before since this place is open 24 hours to crash after partying in kabukicho. Otherwise onsen was nice, they have outside, inside, sauna etc. Having gone to both onsen monogatari and theramae-yu, i think i like onsen monogatari more since the bath area seemed bigger with more choices, although i really enjoyed the outside bath where you can lay down and your only half immersed in the water. Also i didnt try the restraunts here but the food on the menu looked very good, compared to onsen monogatari is more a food mall atmosphere so many choices that you get from different shops and there is central seating area that you can eat at.

Thermae-Yu is amazing. Love that it looks so new and clean (because it is). Spent one Sunday afternoon in December and it wasn't crowded, which was nice. Enjoyed all the baths, especially the carbon dioxide one (imagine sitting in a bath of Perrier), and the outdoor lie down bath where I could see blue sky as my body was half submerged. Rain shower was also great. Korean scrub was good but not as intense as I've had at other places. A bit tricky to navigate arranging a scrub without Japanese but one of the workers helped me make an appointment. Lots of English signs and information throughout so that was good. Have to pay extra for the top floor and I'm glad I did. Laying on heated stone slabs was very relaxing, but you can definitely enjoy this place without it. Even the food was pretty good (chilled udon and tempura with dipping sauce). I only wish I had more than a couple hours to spend but even that was worth it!
