Freshly flash-frozen, half-cut crabs, brimming with roe, are wild-caught from the open sea, naturally grown without artificial farming. The temperature difference between day and night in the seawater nurtures their sweet and tender meat, resulting in thin shells and thick, meaty flesh with a pure ocean flavor, free of any muddy taste. They are flash-frozen immediately at sea by fishing boats to preserve the texture of the live crabs to the greatest extent possible, avoiding the refreezing of overnight chilled crabs.
