Japanese Snow Crab: A Delicacy of the Cold Northern Seas

The Japanese Snow Crab (Chionoecetes opilio), known as “Zuwaigani” (ズワイガニ) in Japan, is one of the most sought-after seafood delicacies in the country.

What is Japanese Snow Crab?

Japanese Snow Crab is a species of cold-water crab found in deep-sea regions ranging from Hokkaido to the western coast of Japan. It thrives in the frigid depths, often at 200 to 600 meters below the ocean surface, where the cold temperatures help develop its firm yet delicate flesh.

These crabs are easily recognizable by their:
✔️ Long, slender legs that contain sweet, juicy meat
✔️ Bright reddish-orange shell when cooked
✔️ Mild yet rich flavor, making them ideal for a variety of dishes

Japanese Snow Crab is commonly caught in the winter months, which is why it is considered a seasonal winter delicacy in Japan.
