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!

Super comfortable place. I went there on a rainy weekday, not crowded at all. definitely can get a great shower, hot spring, and sauna there. For me the price is reasonable. The environment is very modern and clean. But if you're trying to find a traditional sauna place, here might not be your first choice.

Let's be honest, half the people who use this facility are using it as a cheap-ish hostel. For that purpose (catching some quality shut-eye), it's just OK, not great. They oversell the tickets here, and by about midnight to 3am, people are swarming the entire place trying to find a bed/recliner to sleep on. And this place is BIG (7 total floors). But they still ran out of space. Upper floors are way too hot to fall asleep (80ish degrees F). And the bottom floors (B2) have way too many people there, so statistically you're going to definitely have at least 1 or 2 loud snorers that literally echo across the entire area. But 1 unforgivable thing is: The recliners really aren't that comfortable. From the pictures they look like fancy movie theater seats, but for anyone above 5ft10in, your legs are going to stick out already. Not sure why they didn't just purchase those instead of whatever these are. Food was GREAT here though. The restaurant felt high-end, with a big menu, and the food came out delicious and well cooked. That's probably the only saving grace of this place. Some tips: - No tats allowed (except on women). - Everyone must wear the provided pajamas in all co-ed areas. - You get 1 key for your shoe locker. 1 digital wristband for your main locker (after checking in), and an optional key for the bath lockers. - Your wristband is how you pay for food and everything else (a la carte massages, etc) at this facility. The entire bill of your stay is settled at the end. - The daypass is from 9am to midnight. You can add a nightpass that includes midnight to 9am. No re-entry allowed for either package.

A hidden gem in the heart of Shinjuku – relaxing, luxurious, and open 24/7 Tokyo’s best-kept secrets for relaxation. Located just a short walk from Shinjuku Station, its central location makes it incredibly convenient, and best of all—it’s open 24 hours a day. Whether you’re in here for a layover, a late night out, or simply want a break from sightseeing, this place is a sanctuary in the city. Admission starts at around ¥2,400 on weekdays and ¥2,850 on weekends and holidays, which includes access to all spa facilities, towels, lounge areas, and amenities. If you decide to stay overnight, there’s an additional late-night fee of about ¥1,800 (charged from 1:00 AM to 10:00 AM)—still much cheaper and far more enjoyable than staying at a capsule hotel. Inside, the variety of baths is incredible: • Carbonated baths that leave your skin feeling silky and soft • Outdoor open-air baths (rotenburo) with a peaceful atmosphere • Jet massage tubs and electric baths for muscle relief • Cold plunge pool for refreshing contrast bathing • Seasonal herbal baths that change regularly There’s even a lotion-infused “beauty bath” and detoxifying mud packs available in some areas. For women, the powder room is a highlight. It’s fully stocked with KOSE Sekkisei skincare products (toner and emulsion), plus other Japanese brands. There are also facial cleansers, body lotions, hairdryers, curling irons, and even hair straighteners. Everything you need is provided—perfect for travelers with minimal luggage. And after your soak, don’t miss the on-site restaurant on the ground floor. The food is genuinely delicious and satisfying—far better than what you’d expect from a spa facility. Whether it’s a hot bowl of udon or a full set meal, it’s the perfect way to end your visit. In short, Thermae-Yu is a top-tier experience at a very reasonable price. Whether for a few hours of refreshment or an overnight alternative to a hotel, it’s one of the most pleasant ways to experience Tokyo.

Very relaxing experience, I especially enjoyed the lie-down jet baths. The lounge chairs are very nice, but they are NOT massage chairs. It's open 24 hours, but if you go very late at night/early in the morning, you have to pay an extra fee. I was happy with this as it offered extra privacy, but most of the facilities (including the fitness center) will be closed, so in a real sense you are paying more for less.
