From 1910 to 1945, Korea was ruled by the Empire of Japan as a colony under the name Chōsen (朝鮮), the Japanese reading of "Joseon".

Japan first took Korea into its sphere of influence during the late 1800s. Both Korea (Joseon) and Japan had been under policies of isolationism, with Joseon being a tributary state of Qing China. However, in 1854, Japan was forcibly opened by the United States. It then rapidly modernized under the Meiji Restoration, while Joseon continued to resist foreign attempts to open it up. Japan eventually succeeded in forcefully opening Joseon with the unequal Japan–Korea Treaty of 1876. Afterwards, Japan embarked on a decades-long process of defeating its local rivals, securing alliances with Western powers, and asserting its influence in Korea.
