Zuwaigani
the winter crab whose regional names double as brand tags
The signature winter crab of the Sea of Japan coast. Its flesh is delicately sweet and flakes easily, with rich roe whether boiled or grilled. The same species is tagged and named differently at each port, so the landing site becomes the brand.

What it's made of
Boiled meat pulls apart along its fibers into tender flakes, carrying a gentle sweetness that spreads slowly with each bite. The leg meat is never overly firm; it seems to melt just as it hits the tongue. Crack the shell and the crab roe inside is said to be rich and creamy enough that many diners come for that alone rather than the meat. A crab caught just after molting has a still-thin, watery shell and goes by the name "mizu-gani," tasting noticeably different from a fully filled-out one.
How it's made
Bottom trawlers work depths of roughly 200 to 400 meters, scooping the crabs up from the seafloor. Because the meat spoils quickly once landed, boats boil or kill the catch live almost as soon as it reaches port. Males, with their longer legs and fuller meat, fetch higher prices on their own, while smaller females carry roe alongside their crab paste. Landing ports tag each crab's claw in yellow or green to certify its origin and freshness.
Why it took this shape
It lives on the muddy, sandy seafloor of the Sea of Japan's deeper waters, and the cold current there is said to slow its growth. The same species is named differently depending on which port lands it: Echizen-gani in Fukui, Matsuba-gani in Tottori, and Taiza-gani at the small port of Taiza in Kyotango, where only about five small trawlers fish and return the same day, killing the crabs live aboard for exceptional freshness.
Before you go
- How to shop at a supermarketHow to choose prepared foods, sashimi, and packaged sushi, when discount stickers tend to appear, region-only specialties, buying by weight, the checkout and bagging flow, and sampling etiquette at a local supermarket.
- Roadside stations, direct-sale stands, and marketsHow to enjoy buying food near where it's produced, visiting and shopping at morning markets and fish markets, what to expect at farm stands, and finding local food at roadside stations (michi-no-eki).

Dishes in the same style
- AmaebiFormally the northern shrimp, it lives in cold water 200-700m deep. Raw, it carries a pronounced sweetness and a melting texture, which gives it this everyday name. Sold year-round for sashimi and sushi.
- Botan EbiA large shrimp said to be named for the peony-like red markings on its shell. Prized for a sticky, dense texture and strong sweetness, most often eaten raw as sashimi or sushi.

- Known for it here: Kyoto, Kyotango
Landed at Taiza port by a handful of small trawlers that fish and return the same day, killed live aboard for exceptional freshness.
Contrast
- TarabaganiCrab-shaped but biologically closer to hermit crabs. Its thick legs pack in substantial, fibrous meat that pulls apart in strands. Popular in winter hot pot or grilled, mostly landed in Hokkaido.
- KeganiA compact crab whose shell is covered in short bristles. Its real appeal is not the leg meat but the dense, rich innards packed under the shell, in season winter through spring, usually just boiled plain.
