Official reporting confirms that since activation of United States Space Forces – Japan (USSF-Japan) on 4 December 2024, collaboration with the Japan Air Self-Defense Force Space Operations Group (SOG) has grown significantly, including expanded directorates, processes, and closer interoperability with U.S. Forces Japan and US Space Forces Indo-Pacific. A December 2025 update from U.S. Space Forces-Japan states that 'the bilateral alliance between JASDF SOG has strengthened exponentially over the year.' Additional credible coverage documents the activation and subsequent allied engagements that reflect growing cross-domain cooperation. Verdict: True. Reason: multiple official sources describe substantial year-long growth and explicitly characterize the alliance as having strengthened exponentially.
