In the world, Nitchai (Nitchai 
, นิตชัย , Ничай 
) is a very rare dominantly masculine, but seldom feminine first name. The forename Nitchai is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare largely masculine, but seldom girly name. Much more prevalently, Nitchai is the last name as well as the forename.
