What three countries under Japanese control?

During World War II, Japan occupied several territories, but three notable countries under Japanese control were Korea, Taiwan, and parts of China, including Manchuria. Korea was annexed in 1910 and remained under Japanese rule until the end of World War II in 1945. Taiwan was ceded to Japan in 1895 after the First Sino-Japanese War and remained a colony until 1945. In China, Japan established a puppet state in Manchuria in 1931 and later occupied other regions during the conflict.
