Japan has taken a strong stance against nuclear weapons, having signed multiple international agreements and treaties related to disarmament and non-proliferation. To protect itself from threats posed by other countries' nuclear capabilities, Japan relies heavily on deterrence policies and strategies such as maintaining a strong military presence in the region, participating in joint military exercises with other nations, and maintaining close ties with China. Additionally, it possesses an advanced missile defense system known as Aegis Ashore which is designed to intercept incoming ballistic missiles before they reach their targets. Japan also promotes global non-proliferation efforts through various international organizations such as the International Atomic Energy Agency (IAEA) and contributes funds towards initiatives such as the IAEA's Peaceful Uses Initiative.
