Tokyo · Inagi & the Tama hills
Inagi Onsen Toki-no-Irodori
稲城天然温泉 季乃彩（ときのいろどり）
A natural-spring bath complex about 5 minutes on foot from Minami-Tama Station (JR Nambu Line) in Inagi, amid the greenery of the Tama hills. The mildly alkaline water from 1,700 m down is pale amber and soft on the skin; the outdoor area has a free-flowing rock bath, pot baths, lie-down baths, a carbonated bath and seasonal specials, while indoors are a high-concentration carbonated bath, jet baths, a sauna with löyly sessions and a cold plunge. With more room than central-Tokyo spas, its outdoor rest deck among trees is a real draw. Entry: adults ¥1,000 on weekdays, ¥1,200 on weekends and holidays; children ¥520/¥680; bedrock baths extra (¥750 on weekdays). Open 09:00–01:00 on weekdays and 07:00–01:00 on weekends and holidays (last entry midnight). Closed only on the third Tuesday of March, June, September and December. Restaurant, body care and a manga corner on site. About 40 minutes from Shinjuku via the Keiō and Nambu lines, easy to pair with Yomiuriland or a walk in the Tama hills.

A free-flowing rock bath from 1,700 m down, gardens, and a day of rest on the Tokyo outskirts
Inagi Natural Hot Spring Tokinoirodori is a large natural-hot-spring spa opened in 2007 five minutes on foot from Minami-Tama Station on the JR Nambu Line in Inagi, Tokyo. That an onsen facility of this scale exists within about an hour by train from Tokyo is itself unusual, and its signature is a rock bath running a 'beauty spring' drawn from 1,700 metres underground free-flowing. Indoors there are eight kinds of tub on each side (main tub, bubble bath, electric bath, plunge), and outdoors four more — centred on a rustic rock bath — are scattered through the gardens, so there is pleasure in moving from tub to tub amid the seasonal planting. The water is alkaline-family, colourless to faintly tinted, with a clear slickness; true to the name 'beauty spring' the skin turns smooth and stays moist afterwards. The facility's other strength is its design for staying: the 134-seat restaurant 'Shunsai-tei' (soba, udon, seasonal dishes) and three rest rooms — the 'View room' (54 seats) with a good outlook, the 'Kutsurogi room' (31) and the 'Nekokorobi room' (18, a room for lying down) — let you spend the whole day as bath, meal, nap, bath again. The bedrock bath costs extra (+¥750 on weekdays) but has no time limit, includes a robe and mat, and has several rooms with seasonal themes, suiting those who want to sweat more gently than in a sauna (children are not admitted). Admission is ¥1,000 for adults on weekdays and ¥1,200 at weekends and holidays — somewhat high for a Tokyo-area super-sento, though bringing towels lowers the felt cost — and hours run from 9 a.m. (7 a.m. at weekends and holidays) to 1 a.m., so both an early-morning and a late-night bath are possible. Closures are fixed as the third Tuesday of March, June, September and December, so check. About 50 minutes from Shinjuku on the Nambu Line and close to Yomiuriland and Tama Zoological Park, it is a leading onsen of western Tokyo that pairs easily with a family outing.
Circling the rock baths, three rest rooms, and a day of unlimited bedrock bathing
Five minutes on foot from Minami-Tama Station, with a large free car park (198 spaces), so train or car both work. Pay at the entrance (¥1,000 on a weekday), use a free locker, and bring towels or rent them (¥130 small, ¥220 large). The circuit: wash in the indoor bath and go round the main tub, bubble bath and electric bath; step outside and move between the four rock baths in the gardens; then finish with 20–30 minutes in the free-flowing rock bath of the 'beauty spring'. The rock bath's water is clearly slick when stirred, and the gardens hold seasonal trees and flowers, so you can soak amid cherry blossom in spring, green in summer, foliage in autumn or snow in winter. At 40–42°C the water is comfortable for a long stay, and being alkaline it leaves the skin smooth. Afterwards use the three rest rooms as you like — the 'View room' (54 seats) for the outlook, the 'Kutsurogi room' (31) with low tables, and the 'Nekokorobi room' (18) for lying down. The restaurant 'Shunsai-tei' (134 seats) serves soba, udon, set meals and seasonal dishes, and there is bodywork, akasuri and a cut salon, so half a day to a full day can be filled. The bedrock bath (+¥750 on weekdays) has no time limit, so many use it two or three times at 45 minutes instead of a sauna; children are not admitted. Hours run from 9 a.m. (7 a.m. weekends and holidays) to 1 a.m. (last entry midnight), so both an early and a late bath are possible, and it closes only on the third Tuesday of March, June, September and December — check before visiting. Weekend afternoons and evenings are busy; weekday mornings and after 10 p.m. are comfortable.
Practical details and a Tama-area route
Hours are 9:00 to 1 a.m. (last entry midnight; weekends and holidays open at 7:00); closed the third Tuesday of March, June, September and December; adults ¥1,000 weekdays / ¥1,200 weekends and holidays, children ¥520/¥680, bedrock bath +¥750/+¥850 (no time limit), towel rental ¥130/¥220, free parking for 198. Access is five minutes on foot from Minami-Tama Station, 50 minutes from Shinjuku on the Nambu Line, 20 minutes from Chofu IC. Suggested routes: (1) a day in western Tokyo — Tama Zoological Park or Yomiuriland in the morning, a cafe in Tama New Town for lunch, a bath and the bedrock bath at Tokinoirodori in the afternoon, soba in the restaurant in the evening, back to Shinjuku; (2) a rail journey — riding the Nambu Line between Kawasaki and Tachikawa and dropping off at Inagi for the onsen (five minutes from the station, so feasible without luggage); (3) families — a bath right at the 7 a.m. weekend opening, the zoo, then a second bath in the afternoon; (4) a rainy day — a full day inside (bedrock bath, three rest rooms, meals); (5) winter — the snow in the gardens during the quiet hours after 10 p.m. Notes: closed the third Tuesday of March, June, September and December; bringing towels is cheaper; children cannot use the bedrock bath; weekend afternoons and evenings are crowded; cash and cards accepted. Tokinoirodori is the leading onsen of the Tokyo outskirts where 'onsen, rest and food' are all solved within walking distance of a station, and the safest choice when you want a day of rest in the middle of a Tokyo trip.
