Did the Japanese ever occupy U.S. Territory?

The correct answer to this question is true - Japanese once occupied some territory of the United States. During the Second World War, Japanese forces invaded some parts of the United States. They took over and controlled Kiska and Attu in the Aleutian Islands. Japan took over the territory on the 6th of June 1942. They occupied this territory in order to protect the Northern flank of the Japanese Empire.

The United States Navy constructed forces with consistent air bombardment battle against the Japanese forces occupying the island. The United States forces were able to destroy the Japanese station in Attu in May 1943. Towards the end of July of 1943, Japanese forces evacuated from Kiska which saw the end of Japanese forces on the Aleutian Islands.
