'Uni' is the edible gonad (roe) of sea urchin, prized in Japanese cuisine for its briny-sweet, custard-like richness; Hokkaido's main commercial species are Ezo-bafun uni (Strongylocentrotus intermedius) and kita-murasaki uni (Strongylocentrotus nudus), both cold-water species distinct from the smaller southern-Japan varieties.
Divers and boat crews hand-harvest wild urchins from kelp beds off Hokkaido's coasts during short licensed seasons (roughly June–August for bafun, varying by locality); roe is hand-extracted and typically shipped fresh on wooden trays or lightly salted for premium grade.
Japan consumes an estimated 50,000+ tonnes of uni annually and accounts for the large majority of global uni consumption, importing heavily from the US, Chile, Russia and South Korea to supplement domestic Hokkaido/Tohoku wild catch; premium fresh Hokkaido uni commands the highest prices in the global sushi and fine-dining trade.
Uni is not CITES-listed, but Hokkaido fisheries cooperatives (gyokyo) operate strict local catch quotas, size limits and seasonal closures to manage overfishing and kelp-bed ('urchin barren') sustainability concerns; export requires Japanese food-safety (HACCP) certification and destination-country seafood import clearance.
