Strategic Value
Japan's first private-sector-led orbital site — bypasses JAXA-centric Tanegashima/Uchinoura monopoly. Crucial enabler for Interstellar Technologies' ZERO and any future Japanese commercial smallsat launchers. Direct competitor positioning vs. Rocket Lab Mahia for Asia-Pacific SSO market.
