Context

Article 9 of Japan's postwar constitution renounces war and prohibits maintaining "land, sea, and air forces." The JSDF exists as a self-defense-oriented organization under civilian control. Personnel are technically "special civil servants" rather than military members, though functionally they operate as a modern military.

Recent Trends

• Gradual personnel increases since 2010 (from ~225,000)
• Focus on cyber, space, amphibious, and remote-island defense capabilities
