Kasube is a traditional Hokkaido seafood specialty made from skate, particularly species such as the Mejane Kasube. In Hokkaido and the Tohoku region of northern Japan, skates are commonly known as “kasube.”
The cartilage-rich fins are typically cut into pieces and sold as a food ingredient. Kasube has long been enjoyed as an everyday home-cooking ingredient in Hokkaido, making it a distinctive part of the region’s traditional seafood culture.
Rather than being treated as an extravagant delicacy, it is valued for its unique texture and satisfying flavor, with recipes passed down as part of local household cooking.
The most characteristic feature of kasube is its texture. When heated, the cartilage-rich parts develop a soft, slightly sticky and gelatinous mouthfeel.
This unusual texture has earned kasube a loyal following among local diners and makes it quite different from many of the more familiar fish dishes found elsewhere in Japan.
The two most common preparations are simmering and deep-frying. Simmered kasube becomes tender and gelatinous, allowing the distinctive character of the cartilage to shine through.
It can also be deep-fried, creating a contrasting texture and a more richly flavored dish. For travelers interested in discovering everyday Hokkaido cuisine beyond famous seafood such as crab and sea urchin, kasube offers a fascinating taste of local food culture.
