 After the liberation of Korea from Japanese rule, the Name Restoration Order was issued on October 23, 1946, by the United States military administration south of the 38th parallel, enabling Koreans to restore their Korean names if they wished to.However, not all Koreans returned to using their original names, especially Koreans living outside of Korea.Many Zainichi Koreans chose to retain their Japanese names, either to avoid discrimination, or later, to meet the requirements for naturalization as Japanese citizens, while some Sakhalin Koreans who had taken Japanese names were registered by Soviet authorities under those names (which appeared on their Japanese identity papers) after the Red Army occupied Karafuto, and up to the have been unable to revert their legal names to their original Korean ones.
