The Japan Self-Defense Forces (Japanese: 自衛隊, Hepburn: Jieitai; JSDF) are the military forces of Japan. The JSDF comprises the Japan Ground Self-Defense Force, the Japan Maritime Self-Defense Force, and the Japan Air Self-Defense Force. They are controlled by the Ministry of Defense with the prime minister as commander-in-chief.

Since the end of the Cold War, and particularly into the 21st century, increased tensions with China, North Korea, and Russia have reignited debate over the status of the JSDF and their relationship to Japanese society. The JSDF have maintained a close alliance with the United States, and have prioritized greater cooperation and partnership with Australia, India, Taiwan, South Korea, Singapore, the United Kingdom, and NATO, as well as acquiring new equipment and hardware.
