Which two Japanese islands were notably captured during World War II?

The capture of Okinawa and Iwo Jima during World War II was significant due to their strategic location and the intense fighting that characterized those battles. Iwo Jima, located south of the Japanese main islands, was crucial for the United States as it served as an important base for launching air operations against the Japanese mainland. The Battle of Iwo Jima, fought in early 1945, was marked by fierce combat, and the iconic image of U.S. Marines raising the flag on Mount Suribachi became a symbol of American resolve in the Pacific.

Okinawa, captured later in 1945, was the largest and bloodiest amphibious assault in the Pacific theater. The island's capture was vital for the Allies, providing a staging area for the planned invasion of Japan. The battles that took place on these islands not only reflected the high stakes of the conflict but also showcased the tenacity of both Japanese defenders and American forces.

In contrast, the other options mention islands that were either not the site of major battles in the same context or were not captured by American forces during World War II. Honshu and Hokkaido are the main islands of Japan and were not captured; instead, they remained under Japanese control throughout the war
