Japan Expands Military Space Capabilities Amid Rising Geopolitical Tensions

• •Japan plans to rename its Air Self-Defense Force to include space operations.
• •The new satellite constellation system enhances Japan's long-range strike capabilities.
• •Japan's defense budget for space has increased dramatically, indicating a shift towards militarization.

Japan is set to rename its Air Self-Defense Force to the Air and Space Self-Defense Force, reflecting its commitment to space as a core defense domain. This change is part of a broader strategy to enhance military capabilities in response to threats from China and North Korea, including the establishment of a satellite constellation system akin to Starlink. The new space operations group will grow from 310 to approximately 670 personnel, indicating a significant investment in space defense. Japan's defense budget for space has surged from 50.6 billion yen in 2020 to 540.3 billion yen in 2025, focusing on satellite development and surveillance systems. The Ministry of Defense aims to operationalize a dedicated space situational awareness satellite in 2026. This militarization of space raises concerns about Japan's intentions and its shift from a passive defense strategy to a more aggressive posture.
