Yomiuriland Scenic Onsen Kakei-no-Yu
よみうりランド眺望温泉 花景の湯
A scenic-view onsen opened in March 2024 inside the new-style flower park HANA·BIYORI in Inagi, Tokyo. Its crowning feature is an open-air bath perched about 100 metres up, gazing across central Tokyo's skyline, fed by reddish-brown sodium chloride-bicarbonate water (hypotonic, weakly alkaline, high-temperature) from 1,750 metres down - hailed as beauty-skin water. Inside: a high-concentration carbonated bath, silk bath, jet baths, sauna and a paid rock-bath area. The in-house restaurant Bishoku-no-Kiwami is supervised by Ginza Onodera, and there is a reclining lounge with over 10,000 manga plus a Japanese garden. Prices: 2,300 yen weekdays and 2,800 yen weekends/holidays for adults (including onsen tax, loungewear and towel rental). Visitors also enter HANA·BIYORI free, with free shuttle buses every 10 minutes from Keio-Yomiuri-Land Station.

More in this area
Toshimaen Niwa-no-Yu
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.
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.
