History

On 26 December 2007, the Government of Japan made the decision to reform its Defense Agency to the Ministry of Defense in the expectation to have a far-reaching effect on Japan's future military development. The defense policy that has been pursued by Japan is based on the "Basic Policy for National Defense", which was adopted by the Cabinet in May 1957. Japan's main goal of national defense is the prevention of indirect as well as direct aggression from outside enemies.

The Japanese government reformed the Defense Agency to the Ministry of Defense with a ceremony that was attended by then Prime Minister Shinzō Abe and the then-new Minister of Defense Fumio Kyuma. The creation of the Ministry of Defense was in conjunction with Prime Minister Shinzō Abe's continued efforts to ensure a stronger image of the Japan Self-Defense Forces (JSDF). The bill in which to upgrade the Defense Agency to the Ministry of Defense was approved by the House of Representatives (lower house) in November 2007, and the House of Councillors (upper house) in mid-December 2007. Minister Kyuma personally attended a session in the House of Councillors and gave a speech after the bill was approved.

In light of the Defense Agency being transformed into the Ministry of Defense, the JSDF was given the responsibilities of international operations, disaster relief and peacekeeping within the overseas locations.

On 11 September 2019, Taro Kono became the first high profile 'prime minister-ready' politician to head the Ministry of Defense. He has the strongest LDP factional backing of any defense minister thus far. His social media following is second only to Prime Minister Shinzo Abe. He's a leading candidate for post-Abe premiership. Kono previously held the prominent role of foreign minister.

Chain of command

• 1. Prime Minister
• 2. Minister of Defense
• 3. Chief of Staff, Joint Staff

Structure

The Commander-in-Chief of the Japan Self-Defense Forces (JSDF), who does not formally constitute a uniformed military, is the Prime Minister. The Emperor of Japan is a constitutional monarch who does not have political or military authority over the JSDF; that authority rests with the Prime Minister. However, it is important to note that the Emperor formally appoints the Prime Minister to office. The Minister of Defense is responsible for the organization and formulating the national security policy. The budget request is drafted by the Ministry of Finance and making its own legislative proposals to the National Diet.

The Minister of Defense is advised on every concern related to the duties of the Japan Self-Defense Forces by the Chief of Staff, Joint Staff.

From 1950 to 1952, the National Police Reserve led by Minister of State Takeo Ōhashi was formed. It was renamed as the National Safety Force in 1952. In 1952, the Coastal Safety Force, the waterborne counterpart of the National Police Reserve, was founded and led by the Commissioner of the Coastal Safety Force (保安庁長官) Tokutarō Kimura.
