🍱 Shijimi-jiru

“Shijimi-jiru” is a local dish of Shiga Prefecture that uses setashijimi. There are three native clams inhabiting Japan: “yamatoshijimi”,“ mashijimi”, and“ setashijimi”. Currently, most of the clams in circulation are said to be yamatoshijimi. The setashijimi used in Shiga Prefecture's shijimi-jiru is an endemic species that lives only in Lake Biwa. (Compared to yamatoshijimi and mashijimi) Its shell is plump, large, and thick, and the flesh is rich in flavor. Setashijimi inhabits the shallow waters of Lake Biwa to a depth of less than 10m, but due to environmental deterioration such as the reduction of sandy soil, it is said that the habitat of the clams is changing. Until around 1965, setashijimi inhabited Lake Biwa in large numbers, and shijimi-jiru, shigure-ni, and shijimi-meshi were eaten on a daily basis. However, due to changes in the environment, the yield has decreased rapidly. The freshwater clams become plump and delicious when they come fully into season in April starting from December, so they are also called “kanshijimi (cold clams).” Local fishermen say that they are particularly delicious in the spring, when the spawning season is approaching.
