Toyama Bay — Japan's Natural Fish Tank
Toyama Bay drops from 0 to 1,000 metres within a few kilometres — a unique underwater topography creating such rich upwelling currents that UNESCO called it "Japan's natural fish tank." The bay produces shiro-ebi (white shrimp, found nowhere else), buri (yellowtail tuna), and hotaruika. The seafood-focused morning markets at Shinminato Uoichiba are extraordinary.

Local Tips
Toyama Bay is one of Japan's most productive fishing grounds — the deep water (700m) is uniquely close to shore, making the Bay a 'natural fish tank' with extraordinary seafood diversity. Hotaruika firefly squid (season: March–May), buri yellowtail (winter), and shiro ebi (white shrimp, year-round) are the specialties. The Toyama morning markets near the port are the best place to eat them.

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.
