Background
Tanegashima (Nansei Shoto) is the location of Japan's main spaceport. The H3 is a Japanese liquid-fuelled orbital launch vehicle developed for national launches. Rocket launches generate designated danger areas to allow for possible falling stages or debris downrange; the polygon and daily windows reflect the expected impact/clearance area and possible alternate launch days. Mariners should treat these warnings seriously and keep clear while active.
