Toshimaen Niwa-no-Yu
豊島園 庭の湯
An urban spa in front of Toshimaen Station, 20 minutes from Ikebukuro on the Seibu line. Natural hot-spring water drawn from 1,445 m feeds an open-air bath overlooking a Japanese garden, plus a swimsuit 'Bade' pool zone. Adults and teens only (junior high and up), so it stays quiet. Lounges, a restaurant and body care invite long weekday afternoons. No tattoos.

Mixed swimwear bathing over a garden inside Tokyo’s 23 wards — an adults-only spa resort
Niwa-no-yu is one of Tokyo’s finest spa resorts, still operating beside the site of the Toshimaen amusement park that closed in 2020. Two things set it apart: bathing with a view over the ~4,000 m² Japanese garden designed by landscape architect Kenzo Ogata, and the swimwear “Bade Zone” where men and women share thermal pools and saunas — ideal for couples and friends. The water itself, an iodine-bearing strong-salt spring from 1,445 m down, is among the most concentrated in Tokyo. No one under junior-high age is admitted, so it is always calm. At ¥2,600 (¥3,300 weekends) including towels and lounge wear it is pricey for a Tokyo spa, but the night-spa rate after 18:00 (from ¥1,800) suits an after-work visit. Fifteen minutes from Ikebukuro on the Seibu line and 2 min from Toshimaen Station — easier to reach than the bayside mega-spas.
Tips & cautions
- Swimwear required in the Bade Zone (paid rental available); no swim cap needed.
- No children under junior-high age — not for family trips.
- Tattoos not permitted under house rules (cover stickers not accepted).
- Weekend/peak prices jump to ¥3,300–3,400; weekdays or the night spa after 18:00 are the economical options.
- Bedrock bath booked same-day at the 1F front desk; last slot 21:15.
- Many combine it with the Warner Bros. Studio Tour Tokyo (Harry Potter) next to the station — bathe in the evening after the tour.
Getting there
2 min on foot from Toshimaen Station (Seibu Toshima line) or 3 min from exit A2 of Toshimaen Station (Toei Oedo line) — Mukoyama 3-25-1, Nerima-ku. ~15 min from Ikebukuro by Seibu line, ~25 min from Shinjuku by Oedo line. No own parking.
Before you go
- Tattoos are explicitly not allowed, even if covered.
- Last entry is 30–60 minutes before closing.

More in this area
Maenohara Onsen Sayanoyudokoro
Eight minutes from Shimura-sakaue Station in Itabashi, one of Tokyo's most atmospheric super-sento, built around a Showa-era mansion and dry-landscape garden. Free-flowing olive-green spring water in the rotenburo, high-concentration carbonated bath, stone sauna and a soba restaurant. ¥970 weekdays, ¥1,300 weekends and holidays; open until midnight. No tattoos.
Kaiseiyu Onsen Bathhouse (Kamata)
Kamata, 15 minutes by train from Haneda Airport, has Tokyo's densest cluster of 'kuroyu' black-water springs. Kaiseiyu, founded in 1929, is the classic: a coffee-dark natural bicarbonate bath, a high-concentration carbonated pool and a cold plunge, with a goldfish aquarium set into the bath wall. ¥600; a toiletries-and-towel set is sold at the desk. Ideal before a flight or after a late arrival. Tattoos are fine, as in most sento.
Kabe Onsen Ume-no-yu, Ōme
A natural-spring super-sentō on the 5th–6th floors of the building linked by footbridge to the north exit of Kabe Station on the JR Ōme Line. The alkaline simple spring from 1,500 m down is known for leaving skin silky; the top floor has an open-air bath, lying bath, hot sauna and cold plunge plus an outdoor rest deck facing the Tama hills. Open 10:00–23:30 (last entry 23:00); ¥1,000 weekdays, ¥1,150 weekends, cheaper after 21:00. The Baijuan restaurant's weekday lunch-and-bath set is good value. The most convenient day onsen in western Tokyo — stop off on the way back to Shinjuku after hiking Mt Mitake, driving Okutama or browsing Ōme's retro shopping street. Closed the third Wednesday.
