|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.
