In the world, Yoou (คุณ 
, 洋宇 
, Yoou 
) is quite a rare epicene first name. The forename Yoou is habitual in Thailand, where it is a rare unisex name, Morocco, where it is a very rare male name, and China, where it is a very rare gender-neutral name. Much less frequently, Yoou is the last name as well as the forename.
