Kurobe Dam
Japan's largest dam — 186 metres tall and 492 metres wide, built between 1956–1963 at enormous human cost (171 workers died) in the heart of the Tateyama-Kurobe Alpine Route. The dam discharge in summer (late June–mid-October) is an extraordinary spectacle: 15 tonnes of water per second arching from the face. The turquoise Kurobe Lake behind it stretches 6km into the Alps.

Local Tips
The Tateyama Kurobe Alpine Route is one of Japan's great engineering spectacles — tram, cable car, ropeway, trolleybus, and bus connect Toyama to Nagano over 90km of alpine terrain. The dam's seasonal water release (June 26–October 15) creates a dramatic jet of water. Book transport legs in advance during peak season (late April and October).

More in Toyama
Gokayama — Ainokura Village
A UNESCO World Heritage village of gassho-zukuri thatched farmhouses — sister designation to nearby Shirakawa-go but even more remote and almost entirely tourist-free on weekdays. The Ainokura hamlet of 20 farmhouses sits in a narrow mountain valley with no convenience stores or chain restaurants — a genuine time capsule of mountain life.
Himi Fisherman's Wharf
Himi is Japan's most celebrated fishing port for buri (wild yellowtail tuna) — the cold winter buri from Toyama Bay, fed on rich upwelling nutrients, are prized above all others. The Icchome Ichiba market beside the harbour serves buri shabu-shabu, crab, and fresh shiro-ebi in a glass building overlooking the Tateyama mountain range and the sea simultaneously.
Hotaruika — Firefly Squid Season
Every spring (March–June), Toyama Bay hosts the world's largest aggregation of hotaruika (firefly squid) — bioluminescent squid that glow blue while spawning in shallow water at dawn. The Namerikawa coast dawn spectacle is one of Japan's most extraordinary natural phenomena, and the fresh firefly squid served same-morning at local restaurants is impossible to find anywhere else.
