The Japanese colonial period refers to the time when Japan expanded its empire and controlled various territories, particularly from the late 19th century to the mid-20th century. This era included the annexation of Korea in 1910 and the occupation of parts of China, such as Taiwan and Manchuria. Japan aimed to modernize these regions and integrate them into its empire, often leading to significant cultural and economic changes. During this period, Japan implemented policies that promoted Japanese culture and language while suppressing local traditions. The colonial rule was marked by both infrastructure development and harsh treatment of local populations, leading to resistance movements in many areas. The colonial period ended after Japan's defeat in World War II in 1945, resulting in the loss of its overseas territories.
