Kurobe

a hot-spring gorge town reached by one direct shinkansen, and a high alpine route beyond it

July 3–5 (Fri–Sun)

Around the station · on foot

Needs a train, bus, or car

Getting there from Shibuya

to the route from the west, via Toyama (Tateyama entrance)

about 3 hr 36 min · about ¥14,620 · 2 changes

Shibuya → Tokyo → Toyama → Tateyama

This reaches the western (Tateyama) entrance, the better side if you mean to cross the whole route rather than just see the dam.

The Toyama fare is from a fare table that reproduces the JR chart, not a JR first-party page, and the Chiho Railway is a private line not covered by JR passes. Confirm both before booking.

to Kurobe Dam, via Nagano (eastern entrance)

about 4 hr 15 min · about ¥14,810 · 3 changes

Shibuya → Tokyo → Nagano → Ogizawa → Kurobe Dam

This is the shortest way to the dam itself, but it's still over four hours of trains and buses each way — a lot for a three-year-old in one go.

The Nagano–Ogizawa bus and the tunnel bus are not JR services and aren't covered by a JR pass. The route's season is confirmed open in July, but verify the day's segment timetable on the official site before locking an itinerary.

by shinkansen (Hakutaka)

about 2 hr 48 min · about ¥12,510 · 1 change

Shibuya → Tokyo → Kurobe-Unazuki-Onsen

The one part of Kurobe you reach on a single train. Only Hakutaka stops at Kurobe-Unazuki-Onsen — the faster Kagayaki passes it by.

Fare from a JR fare chart reproduction and timing from a ticket aggregator, neither a JR first-party page. Confirm the live timetable before booking.

The high-heat tunnel

tour-only, and not reachable in 2026

Deep in the gorge runs a prewar power-construction tunnel where the rock hit 160°C during digging (dynamite ignited on its own) and still sits around 40°C, served by a 200-metre elevator that swallows whole freight cars. The wildest thing here. — Canyon Route
