Invasion of Japan

Background
The Invasion of Japan was the primary battle of the Second Pacific War, and the only event in that war depicted. It occurred throughout coastal Japan. Prior to the invasion, Genbu Kururugi (father of Suzaku Kururugi) encouraged the Japanese to unite as a single front and defeat the encroaching Britannian presence and protect their homeland. He admitted he was willing to go as far as fighting to the last man if necessary, something Suzaku disagreed with. Suzaku attempted to convince his father to surrender to the superior force and to try and negotiate. Genbu believed that this would dishonor the Japanese, and that was unacceptable regardless of the price. Angered, the two began to fight, and Suzaku attacked his father with a sword, fatally wounding him. Suzaku would then flee the scene, something that would scar him for the rest of his life. After Genbu's death, Japan surrendered easily.

The Battle
The Britannian Naval fleet surrounded the island from the North, East and south, and attacked the island from all positions simultaneously. Drop ship aircraft launched from carriers were used to deposit soldiers and Glasgows behind enemy lines, rendering much of the entrenched military useless. The new Glasgow frames proved themselves an easy match for the scattered soldiers and tanks alike, and the Britannian forces quickly pushed into the countryside. Japanese Forces only managed one success under Lieutenant Colonel Kyoshiro Tohdoh at Itsukushima, a victory that earned him the name Todoh of Miracles (奇跡 の 藤堂, Kiseki no Tohdoh). Surrender came not long after the majority of the Japanese forces had been annihilated.

Aftermath
After the war, Britannia renamed the colonized island Area 11, and all Japanese citizens "Elevens." With their victory they also had complete control over the Sakuradite mines in Japan, and with this resource, Britannia would soar in Knightmare frame research.
