Tochio Onsen Kōjin-no-yu riverside open-air bath

栃尾温泉 荒神の湯(河原の共同露天風呂)

An open-air-only public bath on the gravel banks of the Gamata River at Tochio Onsen in the Okuhida valley. The rock-ringed men's and women's pools have no screen on the river side, so the rushing Gamata and the Northern Alps fill the view — starry skies at night, snow scenes in winter, wild Okuhida all year. Free-flowing simple spring water; there are changing huts but no reception — drop a donation (about ¥300) in the wooden box at the entrance. Open 8:00–22:00 (from 12:00 Mon, Wed and Fri for cleaning); no closing days, but suspended when the river is high. Bring a towel. An easy stop between the Shinhotaka Ropeway and Hirayu, or a night soak for anyone staying in Tochio's inns.

Just a tub on the riverbank: Okuhida at its most elemental

Kojin-no-yu is a community-run open-air bath built on the Gamata riverbed at Tochio Onsen in the Okuhida valley. All there is: two rock-built tubs, men’s and women’s, and wooden changing huts — no roof, no washing area, no attendant; you drop about ¥300 in the box. In return the Gamata river rushes past in front and the peaks of the Hotaka range and Mt Kasa rise beyond — Okuhida’s “bath in nature” in its purest form. Open until 22:00, so many come to soak under the stars.

Tips & cautions

- Mon/Wed/Fri opens at 12:00 after cleaning. Closed in heavy rain or high water.

- You cannot wash here — bathe at your inn first and just soak. Bring a towel; no lockers, so leave valuables.

- Open-air only, so winter (deep-snow country) is harsh between hut and tub — but the snow views are superb.

- The fence is low; women may prefer quieter hours.

- Resident-managed: no car camping, tents or litter; park considerately — access was once restricted after abuses.

Getting there

2 min on foot from the “Tochio-shinryojo-mae” stop on the Nohi bus Hirayu–Shinhotaka line (beside Route 471 on the Gamata riverbank). ~15 min by car from Hirayu bus terminal, ~10 min from Shinhotaka Ropeway. Free parking.
