All around the world, 鯉 (Koi

) is quite a common epicene forename. The forename 鯉 is habitual in Macao, where it is quite a rare masculine name, Japan, where it is quite a rare dominantly male, but infrequently feminine name, and Oman, where it is a rare male name. Not in comparison with a country's population, it most frequently occurs in Japan, India, and Indonesia. Also, 鯉 is the last name as well as the forename.
