Japan is the second-highest-ranked Asian country in the 2022 Global Peace Index, after Singapore. It spent 1% of its total GDP on its defence budget in 2020, and maintained the tenth-largest military budget in the world in 2022. The country's military (the Japan Self-Defense Forces) is restricted by Article 9 of the Japanese Constitution, which renounces Japan's right to declare war or use military force in international disputes. The military is governed by the Ministry of Defense, and primarily consists of the Japan Ground Self-Defense Force, the Japan Maritime Self-Defense Force, and the Japan Air Self-Defense Force. The deployment of troops to Iraq and Afghanistan marked the first overseas use of Japan's military since World War II.
