I went asari clam digging for the first time in my life. There are some seashore/fishing grounds in Japan where many clams grow, and parts are sectioned off for fishermen while parts are for recreational purposes. During Golden Week in Japan, crowds of families and kids tend to gather at these areas, but in the middle of rainy season, the place was almost totally empty. The majority of shellfish living there are asari clams, which are often seen in Japanese supermarkets and used for miso soup, pasta, grilled clams, etc. Be careful when you bring these live clams home, because they spit water like crazy!
