[Machine Translation] The Air Self-Defense Force (JASDF) has 28 radar sites located throughout Japan, which are constantly on the alert 24 hours a day, 365 days a year to monitor Japan's airspace and surrounding airspace. If a suspicious aircraft is detected by radar, fighter jets from bases across Japan scramble to prevent it from approaching or violating Japan's airspace. This film introduces the realities of the air defense missions that have been carried out since the establishment of the Air Self-Defense Force.
