Globally, Matsunami (松波 , Matsunami , まつなみ) is a common predominantly masculine, but very seldom girly forename. The first name Matsunami is habitual in Eastern Asia, particularly China, where it is quite a rare predominantly boy's, but very infrequently female name, and Japan, where it is a very rare female name. Much less frequently, Matsunami is the last name as well as the forename.
