Tokyo hotels with an indoor pool: lanes and rules
Four Tokyo hotels on this page have an indoor pool, and two of them are real 25-metre lap pools: the Bvlgari Hotel Tokyo, on the 40th floor of a tower beside Tokyo Station, and the Okura Fitness & Spa pool that guests of The Okura Heritage Tokyo use in the hotel's Prestige Tower. Hotel Chinzanso Tokyo keeps its pool under a retractable roof beside an onsen fed with water from Ito, and The Prince Gallery Tokyo Kioicho has a heated pool on the 30th floor with a sauna. Guest reviews of the four average 9.5 out of 10 across 1,451 reviews. In Tokyo, the pool you can actually use depends less on the view than on house rules: minimum ages, set hours for children, and how each hotel treats tattoos.
Tokyo keeps its best hotel pools indoors and high up, inside spas on the upper floors of towers or, at Chinzanso, beside a garden in Bunkyo. Swimming here comes with rules: set hours for children, minimum ages and dress codes that are applied to the letter.
Where to stay
Which Tokyo indoor pool suits your trip
Tokyo's winters are cold and the rainy season soaks June and July, so the hotel pools worth booking here are covered and sit inside full spas. Each has its own rules on ages, hours and dress, and those rules decide more than the length of the water.
For lengths with a view, I would book the Bvlgari Hotel Tokyo. Its 25-metre pool is lined in emerald-green mosaic and sits inside an 1,800-square-metre spa on the 40th floor, next to a smaller vitality pool whose fan-shaped mosaic borrows from the Baths of Caracalla in Rome. The hotel opens the pool from 7am to 10pm. Children aged four and over may swim from 9am to 5pm only, while the spa and gym are for guests aged 16 and over, so the early morning and the evening are the adult hours.
The Okura Heritage Tokyo is the 17-floor wing of The Okura Tokyo, and its guests swim at Okura Fitness & Spa, on the 27th floor of the Prestige Tower next door: a heated 25-metre pool with five lanes and natural light, with showers and a relaxation room. It runs Monday to Saturday from 6am to 10pm, last entry 9pm, and on Sunday until 9:30pm. Only children aged 13 and over are admitted. The Okura Tokyo, booked as the Prestige Tower itself and rated 9.6 from 1,699 reviews, is not in this selection but shares the same pool.
Hotel Chinzanso Tokyo, in the Sekiguchi district of Bunkyo, is the one for a swim followed by a hot bath. Its warm, all-weather pool sits under a retractable roof inside the hotel spa, beside an onsen whose water comes from Ito on the Izu Peninsula. The spa opens from 6am to 10pm, last entry 9:30pm. Children aged 4 to 12 may come only from 8am to 6pm with a guardian, and under-4s are not admitted. Swimwear can be rented at the spa. The pool's length is not published, so I would not choose it for training.
The Prince Gallery Tokyo Kioicho fills the top floors of the Tokyo Garden Terrace Kioicho tower, and its heated indoor pool is on the 30th floor, with loungers facing the windows and a sauna. The spa opens from 6:30am to 10pm, last entry 9:30pm, and the pool closes from 7 to 13 January 2027 for maintenance. Swimmers must be 13 or over, and 13 to 15-year-olds change in their room, since the locker rooms and baths start at 16. The tower connects directly to Akasaka-mitsuke and Nagatacho stations, handy on a wet day.
The surprise for many visitors is the house rules. Japanese hotel pools treat tattoos anywhere from a full ban to a request to cover up with a rash guard. The Prince Gallery states that it may refuse entry to guests with tattoos, while the other three do not state a rule on the pool pages I read, so write to the hotel before booking if this concerns you. Swim caps are required at almost every public pool in Japan and at some hotel pools. For an outdoor swim in summer, TRUNK(HOTEL) Yoyogi Park, not on this page, has a rooftop pool.
A traveler's takeI would stay at the Bvlgari Hotel Tokyo to swim, and I would go down before 9am, when the 25-metre pool is still closed to children and the water is quiet. For an adult swimmer who wants five proper lanes, the Okura pool used by Heritage Wing guests is its equal, and it opens at 6am every day. With children under 13, I would skip both and book Hotel Chinzanso Tokyo, where 4 to 12-year-olds swim from 8am to 6pm and the onsen waits afterwards. The Prince Gallery is the one for a short business trip: its pool suits a soak more than a workout, and its tower connects directly to two metro stations.
Indoor poolBvlgari Hotel Tokyo
Luxury rooms, a swimming pool with a view, and exceptional spa facilities
Why guests love itBvlgari Hotel Tokyo holds a 9.8, among the highest ratings in the city, built on an indoor pool with a view alongside serious spa facilities including a hot tub and sauna. The Italian, sushi and vegetarian dining options give it more range than most luxury hotels manage in one address. It suits travellers marking a special occasion or wanting the top tier of Tokyo hospitality, more than budget-conscious visitors passing through for a night or two.
Indoor poolThe Okura Heritage Tokyo
Elegant rooms, extensive spa, and an indoor pool in the heart of Tokyo
Why guests love itThe Okura Heritage Tokyo holds a 9.4 with elegant rooms and extensive spa facilities, including an indoor pool and jacuzzi, alongside a fitness centre. The dining lineup runs from Chinese to French cuisine, a genuinely broad spread for a single hotel. It leans on the same understated, service-driven approach that defines the wider Okura brand, making it a solid pick for travellers who want a calm, well-run stay in a prime part of the city rather than a headline-grabbing pool.
Indoor poolThe Prince Gallery Tokyo Kioicho, a Luxury Collection Hotel
Luxury Tokyo hotel with an indoor pool and direct metro access
Why guests love itThe Prince Gallery Tokyo Kioicho holds a 9.4 as a luxury hotel with direct access to both Akasaka-Mitsuke and Nagatacho stations, a genuine advantage for travellers who want to reach any part of Tokyo without a taxi. The indoor pool and fitness centre cover wellness, while the sake bar, sushi and teppanyaki restaurants keep dining on-site rather than requiring a search elsewhere. It suits business travellers and independent visitors alike who value transit access as much as five-star service.
Indoor poolHotel Chinzanso Tokyo
Luxury hotel with a historic garden, indoor pool, and hot springs
Why guests love itHotel Chinzanso Tokyo holds a 9.4, set inside a historic Japanese garden in Bunkyo rather than the glass-tower districts most visitors associate with the city. Its glass-enclosed indoor pool looks out over the grounds, and the spa runs traditional Japanese hot-spring baths alongside it, a genuinely different pool experience from a standard hotel tank. Deep soaking bathtubs in the rooms extend that theme. It suits travellers who want quiet and garden scenery over Shinjuku-style density.
Local tips
- 1At the Bvlgari Hotel Tokyo, swim between 7am and 9am or after 5pm if you want the 25-metre pool without children, who are admitted only from 9am to 5pm.
- 2If your stay at The Okura Heritage Tokyo falls between 12 and 15 January 2027, the Okura Fitness & Spa pool is closed for inspection and maintenance, so move a swimming trip by a few days.
- 3On Sundays the Okura pool closes earlier, with last entry at 8:30pm instead of 9pm, so keep a late swim for a weekday or Saturday evening.
- 4From The Okura Heritage Tokyo, the pool is in the Prestige Tower next door, on the 27th floor; the hotel asks guests not to arrive in nightwear, bathrobes or slippers, so dress before you walk over.
- 5Hotel Chinzanso Tokyo rents swimwear at its spa, useful if you packed for a city break and decide on the spot to try the pool and the Ito spring water.
- 6Pack a swim cap for Japan: caps are required at almost every public pool and at some hotel pools, and having your own avoids a hunt at the spa desk.
- 7If you have tattoos, write to the hotel before booking and pack a long-sleeved rash guard, since Japanese hotel pools range from a ban to a simple request to cover up.
- 8With a child under four, none of the four pools will work: Chinzanso and the Bvlgari admit children from age four, and the Okura and Prince Gallery pools only from 13.
