|Japanese Self Defense Forces|
|Name||Japanese Self Defense Forces|
Due to the nature of Japan's constitution after the end of World War II, Japan lost its military capability and was forced to rely on the U.S. for security and protection. As the Cold War in the Korean Peninsula escalated, American forces began to leave Japan in order to fight in the Korean War, which left Japan virtually defenseless.
Under American occupation authority's recommendation, the Japanese government authorized the establishment of a National Police Reserve in July 1950. This then led to the Treaty of Mutual Cooperation and Security between the United States and Japan, stating United States forces stationed in Japan were to deal with external aggression against Japan while Japanese Forces would deal with internal threats and natural disasters.
After undergoing policy changes, including being renamed National Safety Forces and creation of the National Safety Agency and the Navy, Japan reorganized into the three distinct branched of the JSDF that are known today.
Gate-thus the jsdf fought there
The JSDF is shown to have a titanic advantage in term of technology advancement with their modern firearms and armored vehicle compared to the Empire's, as well as the Special Region's generally primitive level technology, making them mostly overpower the Empire multiple times. Despite the obvious fact that the JSDF can wipe out the Empire or conquer the Empire with their military might with ease, the JSDF is forced to restrain themselves from doing all of that by the watchful eye of the global community and especially the superpowers like US, China or Russia who want to seize the Gate for themselves to seize natural resources from the Special Region.
Furthermore, Prime Minister Morita also states that Japan doesn't have enough force or resources to occupy the whole Empire due to their low population and relatively small military in the global scale compared to US, China and Russia.
