Following the 2020 U.S. Department of Defense UAP video releases, the Japanese Defense Minister publicly announced standardized protocols for SDF aircrew. Personnel must report any observed UAP immediately, attempt to capture photographic or video evidence when safe and feasible, and include contextual information. The Ministry will conduct or coordinate analysis, potentially incorporating public reports and allied intelligence. The instructions clarify that no prior SDF encounters with UFOs had been recorded, but the procedures were established to ensure readiness for any object posing a potential threat to Japanese airspace or security. Later clarifications addressed unmanned aerial intruders (such as balloons) under existing Self-Defense Forces Law, permitting necessary measures including force if an object violates airspace. The policy does not conclude that any observed phenomena are extraterrestrial; it treats them as objects requiring identification for defense and aviation safety purposes. No public database of cases has been released, consistent with the absence of confirmed SDF encounters.
