Watch the trolley trains roll by — a rotenburo on the shore of Lake Unazuki
Tochi-no-yu is a day-bath on the shore of Lake Unazuki, the dam reservoir 3 km up the Kurobe River from the Unazuki spa town, sitting across from the Kurobe Gorge Railway line so that you can watch the orange trolley trains cross the iron bridge over the river while soaking in the rotenburo. It is a simple set-up — one indoor tub and one outdoor bath per gender — but the outdoor bath faces an emerald lake and the mountains of the gorge, with autumn colours or early-summer greenery reflected in the water. The water is the same mildly alkaline simple spring from the Kuronagi source as Unazuki, adjusted to about 41.5–42 °C, clear and silky. For ¥510 soap, shampoo, dryers and lockers are included, so you can come empty-handed, and the free electric shuttle “EMU” from the spa town runs out here, so no car is needed. Like the gorge railway, though, it shuts for snow from early December to mid-April and has irregular closures in season, so check ahead. The best plan: ride the trolley train to Keyakidaira and back, then drop in before last entry at 16:30.
Tips & cautions
- Open mid-April to early December, 10:00–17:00 (last entry 16:30) — short hours, so plan around the trolley train. Irregular closures — check with the tourist office (0765-62-1122).
- The rotenburo is not far from the bridge and tracks and can be faintly seen from passing trains — use the indoor bath if that bothers you.
- Towels ¥300; other amenities included.
- Restaurant suspended — eat in the spa town.
- The free EMU shuttle runs limited hours — miss the last one and it’s a 3 km walk (~40 min, with a tunnel section).
- Tattoo policy unconfirmed — ask at reception.
- Autumn colours peak early to mid-November, when weekends are crowded on both the railway and in town.
Getting there
~10 min / 3 km by car from Unazuki-Onsen Station (Toyama Chiho Railway), Oo 6215, Unazuki-Onsen, Kurobe — or the free EMU electric shuttle around the spa town. By car ~15 km / 25 min from Kurobe IC (Hokuriku Expressway) via Pref. Roads 53, 14, 63 and 13; 30–35 free spaces. Tel. 0765-62-1122.
