The Hokki clam, also known as the Surf Clam, is a bivalve mollusk primarily found in the coastal waters of Japan, especially around Hokkaido. Its official name is "Ubagai," but it is commonly referred to as "Hokki clam" due to its distinctive shape. The clam has a thick shell with a bright red interior. The texture of Hokki clam is chewy, and it has a strong sweet flavor, making it exceptionally delicious. It is widely used in various dishes such as sushi, sashimi, vinegar dishes, and hot pots. Fresh Hokki clam sashimi is particularly prized for its sweetness and firm texture. In Hokkaido, there are many regional specialties like "Hokki Curry" and "Hokki Rice." Hokki clam is valued not only for its taste but also for its high nutritional content, making it a healthy addition to the diet.
