Japan (日本国 Nihon-koku) officially known as the Republic of Japan is a sovereign island country in East Asia. The country is a member of the Earth Space Defense (ESD). Previously an imperial power, Japan was devastated in World War II following the atomic bombings of Hiroshima and Nagasaki, and has since maintained a unitary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
During the War of 1996, an alien City Destroyer hovered over Tokyo and destroyed the city in which it sustained the highest number of human casualties on Earth. The City Destroyer then proceeded to destroy the cities of Yokohama and Nagoya. During the July 4th counteroffensive, Japanese armed forces engaged against the Tokyo City Destroyer and an additional Destroyer coming from the Korean peninsula over Osaka and Hiroshima, respectively.
In the aftermath, Japan was devastated and over 30 million people perished in the attacks. Tokyo, Nagoya, and Yokohama were destroyed. Japan had suffered higher casualties than any other nation after the attacks. After the war, Japan's remaining populace began reconstruction processes to rebuild their damaged cities. It also joined the Earth Space Defense.
