Joo (Korean name)

Revised RomanizationJu

Joo ([tɕu]), also spelled Ju or Chu, is a Korean family name and an element in Korean given names. Its meaning differs based on the hanja used to write it.

Family name[edit]

As a family name, Joo may be written with either of two hanja, one meaning "red" (; 붉을 주), and the other meaning "around" (; 두루 주). The former has one bon-gwan (Wu Yuan, China), while the latter has four (Sangju, Gyeongsangbuk-do; Chogye-myeon, Hapcheon-gun, Gyeongsangnam-do; Cheorwon-gun, Gangwonnam-do; and Anui-myeon, Hamyang-gun, Gyeongsangnam-do). [1] The 2000 South Korean census found 215,010 people with this family name.[2]

In a study by the National Institute of the Korean Language based on 2007 application data for South Korean passports, it was found that 50.6% of people with this surname spelled it in Latin letters as Ju in their passports, and another 46.9% spelled it as Joo. Rarer alternative spellings (the remaining 2.4%) included Chu and Choo.[3]
