Japanese post in Korea

Post offices in Wonsan and Incheon (Chemulpo), ports which had also been opened to foreign trade by the treaty, were established in 1880 and 1883, respectively.

Additional Japanese post offices/agencies were opened from 1896, particular from 1899, first in other treaty ports including Masan and Gunsan, then other inland places, predominantly as a political measure, as few initially made a profit.

The inauguration of a Korean postal system initially was attempted in November 1884, but soon was interrupted by the Gapsin Coup half a month later, and officially terminated.

Many foreigners resident in Korea, including many Japanese, preferred to use the Korean postal service to write overseas, as the depreciated Korean silver currency resulted in somewhat cheaper postal rates.

However, following the Russo-Japanese War and the annexation of Korea in 1905, the entire Korean Empire postal services became amalgamated with the Japanese postal services, and Japanese post stamps continued to be used in Korea until the end of World War II.
