Low tide comes twice a day. It costs about 1,000 to 2,000 yen a person. Sometimes, it costs nothing. Some fisherman's cooperatives take control of some areas. But usually, people spend about half a day on the beach.
Some people use scoops and rakes to dig.
Others use their own hands. Not only children but also grown-ups have fun digging shells. People take home the shells they dug, and enjoy eating. Photographs contributed by Kenji Aoki.
