Korean Chinese in Japan, also called Chaoxianzu in Japan (在日朝鮮族, ざいにちちょうせんぞく; Korean: 재일조선족) are ethnic Koreans who hold Chinese nationality and reside in Japan.
They have "Joseon" (simplified Chinese: 朝鲜; traditional Chinese: 朝鮮; pinyin: Cháoxiǎn) listed as the ethnicity on their household registrations in China, but they are simply considered Chinese nationals by the Japanese government.
It has been argued that the Korean Chinese society in Japan is very different from that of the Korean Chinese (Chaoxianzu) in Korea.
The Korean Chinese community in Japan began to take shape in the late 1980s due to an influx of international students.
This trend saw a significant increase in the mid-1990s as more Chinese people pursued higher education in Japan or other countries, marking a notable expansion of the Korean Chinese presence.
