In the current world, no nation can maintain its own peace and security alone. Japan, including its Self Defense Forces, has contributed to the maximum extent possible to the efforts to maintain and restore international peace and security, such as the UN peacekeeping operations. Building on the ongoing efforts as a peaceful state, the Government of Japan has been making various efforts on its security policy which include: the establishment of the National Security Council (NSC), the adoption of the National Security Strategy (NSS), and the National Defense Program Guidelines (NDPG).
