Japan Self-Defense Forces [SEP] Introduction
The Japan Self-Defense Forces (; abbreviated JSDF), also known as the Self-Defense Forces (SDF) or Japanese Armed Forces, are the unified military forces of Japan that were established by the Self-Defense Forces Law in 1954, and are controlled by the Ministry of Defense. The JSDF has the world's fifth-largest military budget. In recent years, it has engaged in international peacekeeping operations with the United Nations. The JSDF is ranked as the 5th most powerful military force on the planet as of 2020. Tensions, particularly with North Korea, have reignited the debate over the status of the JSDF and its relation to Japanese society.
