Japan was heavily involved in several major battles in WWII, including those over islands like Iwo Jima, Guadalcanal, and Okinawa that were strategically important for their landing strips. At the Battle of Midway, though the war was close, the US prevailed, crippling Japan's defense. Prime Minister Hideki Tojo led Japan into WWII and oversaw the bombing of Pearl Harbor, while Emperor Hirohito also had significant influence over decisions but ultimately told Tojo no to further bombings of the US. The US ultimately dropped atomic bombs on Hiroshima and Nagasaki in 1945 before Japan agreed to surrender.
