In-depth comparison of Japan's three major sea urchin regions. Flavor, season, price, and suitable dishes provide Macao restaurant chefs and sea urchin enthusiasts with scientific purchasing guidance.

The Japanese sea urchins available in the Macao market are mainly from three regions: Hokkaido Bafun Uni (sweetest, season June-September), Aomori Purple Sea Urchin (most savory, season May-August), and Nagasaki Red Sea Urchin (winter delicacy, season October-March). Inari Global Foods is Macao's only importer supplying all three regions.

Why Region Determines Sea Urchin Quality

80% of Japanese sea urchin quality differences come from the region's water temperature, seaweed food source, and harvest timing. Even with Bafun Uni, Rebun Island in Hokkaido has about 30% higher sweetness than other regions, resulting from lower water temperatures and abundant kelp food chains.
