Why go
- 100% source water from Paleozoic strata
- Open-air bath overlooking the Tama River
- Ten minutes from the station, easy to pair with hiking
A 100% source bath within walking distance of Okutama Station
Moegi-no-Yu is a day-trip spa about ten minutes on foot from Okutama Station on the JR Ome Line. Most of Okutama's springs require a car, which makes this one of the few you can simply walk to, ideal for stopping after a climb or a valley walk. The baths run on 100% source water; from the open-air bath you look over the Tama River and the ridges beyond, and the indoor bath's windows frame Okutama's mountains and trees. Inside there is a dining hall, a rest area and a shop, so you can linger after bathing.
Water from Paleozoic rock, and baths that change monthly
The source is Okutama Onsen, carrying metaboric acid and fluorine, at 21.8 °C. It comes from deep within Paleozoic strata, said to be Japan's oldest rock, and is used undiluted. There are two bath halls, upstream and downstream, and the men's and women's sides swap each month: in April the upstream bath is women's and the downstream men's, in May the reverse. The open-air bath lets you soak to the sound of the Tama River while the mountains change with the seasons.
The three-hour limit and seasonal hours
Charges are by the hour: ¥1,200 for three hours for adults and ¥300 for each hour after, bathing tax of ¥50 included. Elementary students pay ¥600 and young children are free. Hours are 10:00–20:00 from April to November and 10:00–19:00 from December to March, with last entry an hour before closing. It is closed on Mondays, or the next day when Monday is a holiday. Hours may change with weather or crowds, and the foot bath is currently closed. Families should also note that children aged 7 and over may not bathe with the opposite sex under Tokyo's ordinance.
