JAXA is Japan's national space agency. H3 (operational since 2024) is the new flagship launcher built with Mitsubishi Heavy Industries. Epsilon is the small-launcher for smaller payloads. Tanegashima Space Center hosts most JAXA launches; Uchinoura handles smaller Epsilon missions. LaunchDetect publishes an independent record of every JAXA launch.
