In the 1930s and 1940s, Japan seemed intent on colonizing all of Asia. It seized vast swathes of land and numerous islands;
Korea was already under its control, but it added
Manchuria, coastal China, the Philippines, Vietnam, Cambodia, Laos, Burma, Singapore, Malaya (Malaysia), Thailand, New Guinea, Brunei, Taiwan...

British India in the
Kohima campaign.
