Before or after the gorge train — the canyon’s spring water at a ¥510 bathhouse by the station
Unazuki Onsen, at the mouth of Toyama’s Kurobe Gorge and the starting point of the Kurobe Gorge Railway’s trolley trains, is the prefecture’s largest spa town, developed in 1923 by piping a roughly 98 °C source 7 km from Kuronagi Onsen deep in the gorge. At its centre, right in front of Unazuki-Onsen Station on the Toyama Chiho Railway, the communal bathhouse “Yumedokoro Unazuki” opened in 2016 — four storeys, with “Momo-no-yu” on the 2nd floor (after Unazuki’s old name Togen, “peach plain”) and “Tsukimi-no-yu” on the 3rd with an open-roofed outdoor tub, swapped between men and women daily, in tubs of Kurobe River granite. The mildly alkaline simple spring is clear and fairly hot, and as soft as its local reputation for making skin “tsube-tsube” (silky) suggests. The ground floor has two free footbaths, a drinking fountain, a tourist office and a lounge — ideal while waiting for the trolley train — and at ¥510 with soap and shampoo included it costs nothing extra to arrive empty-handed. The gorge railway runs from late April to November, when Unazuki is busy, but the bathhouse is open all year (closed the 4th Tuesday), so you can also enjoy the snowbound gorge mouth in winter quiet. In summer, pair it with the riverside rotenburo Tochi-no-yu (¥510) upstream.
Tips & cautions
- Closed 4th Tuesday and 1 January. Reception until 21:00.
- Baths swap daily — ask at the ground-floor desk which side has the 3rd-floor “Tsukimi-no-yu” with the outdoor tub.
- The water is hot (cooled from a 98 °C source) — take care with children.
- Ground-floor footbaths and drinking fountain are free — worth it even if you only have minutes.
- Book the trolley train (late April–November) in advance in peak season, especially autumn colours (late Oct–early Nov).
- Tattoo policy unconfirmed — it’s a public bathhouse, so ask at reception.
- Unazuki’s ryokan also offer day bathing (¥1,200–1,500) — go there or to Tochi-no-yu if you want a proper rotenburo.

Himi Onsen Soyu
Next to the Himi Banya-gai seafood market near the port famous for winter yellowtail, a day spa fed by its own well 1,250 m down. The brown, strongly saline water flows freely, and on clear days the rotenburo frames the Tateyama range across Toyama Bay. Open 10:00–23:00, from 7:00 on weekends and holidays. ¥950. The classic routine: kaisen-don or conveyor sushi at the market, then a soak.
Kintarō Onsen Karuna no Yakata
Ten minutes by car from Kurobe-Unazuki-Onsen Station on the Hokuriku Shinkansen, a large day-spa wing of the lone inn Kintarō Onsen in Uozu. Its sulfur-rich sodium-calcium chloride water is among the most concentrated in Hokuriku, gushing at 1,800 litres a minute. A giant rock bath built from Tateyama boulders, open-air baths, a carbonated bath, rock-bath rooms and four private baths; open daily 8:30–23:30. Admission ¥1,100.
Unazuki Onsen Tochi-no-yu
A city-run day bath on the shore of the Unazuki dam lake. From the lakeside open-air bath you can watch the Kurobe Gorge trolley train crawl along the far cliff — a favourite with railway fans.

Five minutes from Unazuki-Onsen Station by the free 'EMU' shuttle or car.
