) is a rare principally girly, but scarcely male given name. The forename Itoyo is characteristic of Japan, where it is a rare girly name, Nigeria, where it is an extremely rare epicene name, and China, where it is an extremely rare masculine name. Very seldom, Itoyo is the last name as well as the forename.
