Characteristics

Lake Ogawara Brackish Water Clam is a Yamato Shijimi (Freshwater clam; Corbicula japonica) caught in the Ogawara Lake. Generally, the size of the clam is over 1.5 centimeters. Due to its large size, it is enjoyed not only for a broth but also for its meat itself. Additionally, the use of engine motored boats is prohibited when towing catching equipment, but uses special catching equipment called “Jyoren”. This keeps shells undamaged, and helps maintain the freshness after shipping. The quality of Lake Ogawara Brackish Water Clam is controlled at the wholesale market, which only deal freshwater clam, and therefore the quality is high and always stable.
