Remarks. This species has been found around the Sea of Japan (= the East Sea), the Seto Inland Sea, and the Pacific coast of Honshu and Hokkaido, Japan (Okubo 1980; Nakao & Tsukagoshi 2002; Smith & Kamiya 2003), as well as Korea (Lee et al. 2000). It is a brackish water species, typically found in estuaries, but it has also been recorded from freshwater rockpools along coasts (Smith & Kamiya 2006).
