Which islands did the Japanese occupy during the Aleutian campaign?

The correct answer highlights the specific islands of Kiska and Attu, which were indeed the locations occupied by Japanese forces during the Aleutian campaign in World War II. This campaign was part of a broader strategy by Japan to extend its defensive perimeter and involve the U.S. in a multi-front war.

Kiska and Attu are part of the Aleutian Islands chain in Alaska, which the Japanese aimed to control to launch possible attacks on the U.S. mainland. The occupation of these islands was notable for the challenging weather conditions and rugged terrain, making the military operations particularly difficult for both forces involved.

The other options reference various Strategic islands in the Pacific, but they did not see occupation during the Aleutian campaign. Hawaii and Guam were significant in the broader context of the Pacific War but did not have ties to the Aleutian campaign specifically. Midway and Wake were critical battle sites where significant naval engagements took place, but these were not occupied during the Aleutian campaign. Adak and Amchitka, while also part of the Aleutian Islands, were primarily used as bases for American operations rather than being occupied by Japanese forces.
