Japan's Colonial Rule in Korea During World War II and Its Lasting Impact

cultural-heritage · 2026-03-20

Japan's occupation of Korea, which began with formal annexation in 1910, intensified during World War II as the peninsula served as a logistical base for Japanese military campaigns in China and the Pacific. While many Koreans resisted through nationalist movements like the Provisional Government in exile and the Korean Liberation Army, others collaborated with Japanese authorities or were conscripted into military and labor roles. The occupation involved forced assimilation policies, suppression of Korean culture, and widespread use of forced labor and sexual slavery. Following Japan's surrender in 1945, Korea gained independence but was partitioned along the 38th parallel, leading to separate governments in the north and south and eventual conflict. The legacy of this period continues to influence regional relations and historical memory.
