JAXA Tanegashima Space Center (TNSC) is Japan’s largest rocket-launch complex, covering about 9.7 million square meters on Tanegashima. Its Yoshinobu Launch Complex, spacecraft test and assembly buildings, and range-control facilities support launch-vehicle assembly, satellite preparation, launches, and post-liftoff tracking. Visitors can explore the free Space Museum (09:30–16:30; closed Mondays, or Tuesdays after a Monday holiday, plus December 29–January 2) and join a free guided bus tour on museum-open days with advance booking. Museum access, tour routes, and schedules can change because of launches, tests, weather, or other events; groups of 10 or more need advance museum reservations.
