All over the world, Koshikawa (越川 
, Koshikawa 
, Косикава 
) is a rare principally masculine, but very seldom girly given name. The forename Koshikawa is habitual in Eastern Asia, particularly China, where it is a very rare primarily boy's, but scarcely feminine name, and Japan, where it is a very rare male name. Very seldom, Koshikawa is the last name as well as the forename.
