Chongryon
The General Association of Korean Residents in Japan (Chae Ilbon Chosŏnin Ch'ongryŏnhaphoe in Korean or Zai-Nihon Chōsenjin Sōrengōkai in Japanese), abbreviated to Chongryon (Korean: 총련, Hanja: 總聯) or Chōsen Sōren (Japanese: 朝鮮総連), is one of two main organisations for Zainichi (or Jaeil) Koreans (long-term Korean residents in Japan), and has close ties to North Korea (DPRK). As there are no diplomatic relations between the two states, it has functioned as North Korea's de facto embassy in Japan.
Chongryon members primarily consist of those who have retained their registration as Joseon nationals (Japanese: Chōsen-seki), instead of taking or being born with Japanese or South Korean nationality. Joseon nationality was a legal status that the Japanese government defined in the aftermath of World War II, when the government of the Korean peninsula was in an undetermined state. Prior to the end of World War II, Korea was administered by the Japanese government as being part of Japan, thus the legal nationality of Koreans, both in Japan and in Korea, was Japanese.
