Across the world, Tjah (Tjah
) is a rare primarily boy's, but very seldom feminine first name. The forename Tjah is characteristic of South-eastern Asia, particularly Indonesia, where it is a rare predominantly masculine, but scarcely girly name. Much less frequently, Tjah is the last name as well as the forename.
