Japanese Kani: Crab Preparations and Regional Culture
Japan — Hokkaido (hairy crab/kegani) and San'in Coast (matsuba/zuwaigani)
Kani (蟹, crab) culture in Japan reaches an intensity found in few other culinary traditions worldwide — entire tourism economies in Hokkaido and the San'in Coast (Tottori, Hyogo, Kyoto prefectures) are built around specific crab species during their winter seasons. The primary Japanese crabs are: zuwaigani (ズワイガニ, snow crab / queen crab), the elegant long-limbed crab famous for its sweet, delicate flesh; kegani (毛蟹, hairy crab), a smaller crab with extraordinarily rich, buttery internal paste (kanimiso) considered more prestigious than the claw meat itself; tarabagani (タラバガニ, king crab), primarily from Hokkaido — enormous, with sweet, firm claw meat. Regional branding extends to licensed catch designations: zuwaigani caught on the Tottori coast are branded 'Karo Gani' or 'Matsuba Gani' with individual tags attached to the claw. Male zuwaigani are larger (called 'Matsuba') while females are smaller but more intensely flavoured (called 'Kobako-gani' in some regions). Crab is consumed at specialized kani-ryori restaurants that serve the entire animal in multiple preparations: raw (kani sashimi), steamed, grilled, in dobin-mushi (crab broth in a ceramic pot), and as zōsui (crab rice porridge) using the shell broth. Kanimiso — the hepatopancreas (creamy brown internal paste, not actual miso) — is considered a luxury condiment and eaten directly from the shell.
