In all the world, Kotaka (Kotaka 
, コタカ ) is quite a rare predominantly male, but very seldom female first name. The forename Kotaka is characteristic of Japan, where it is a rare primarily male, but scarcely female name, India, where it is an extremely rare mostly female, but infrequently male name, and China, where it is an extremely rare unisex name. Much less frequently, Kotaka is the last name as well as the forename.
