Misson of JMSDF
Japan is an island country surrounded on all sides by the sea. That means any threats to our country will always approach us via the sea. In addition, Japan lacks natural resources, so it must rely on countries overseas for most of the materials that we require in our daily lives. We use a maritime transport network stretching around the globe to obtain more than 90% of these materials. In recognition of new security environment, the Defense Program Guidelines defines the role of the defense forces as "effective response to the new threats and diverse situations," "Proactive efforts to improve the international security environment," and "preparation for full-scale invasion," which is the primary role of defense forces, and Japan will efficiently maintain the necessary Maritime Self-Defense Forces posture to effectively carry out missions in each the areas.
