History

Historical Context

Japan established the Maritime Self-Defense Force (JMSDF) in 1954, following the dissolution of its imperial military after World War II. Initially reliant on the U.S. for defense, Japan's military capabilities expanded amid Cold War tensions, leading to over 200 joint exercises with the U.S. The recent transit of JS Ikazuchi through the Taiwan Strait underscores Japan's assertive stance in regional security, particularly against China's territorial claims.
