In the world, ヨンジャ (Young-Ja 
, Yonja , ヨンジャ) is a very rare dominantly girly, but uncommonly boy's first name. The forename ヨンジャ is habitual in Northern America, particularly the United States, where it is an extremely rare gender-neutral name. Very seldom, ヨンジャ is the last name as well as the forename.
