The ADS-B network is not responding, so this page found nothing — that is a fault at our end and says nothing about how many Japan Air System aircraft are flying. It normally clears within a few minutes.
How this page finds Japan Air System aircraft
There is no way to ask the ADS-B network for “every Japan Air System aircraft” — the network reports by position, not by operator. So this page looks around the airline's busiest airports and keeps the aircraft whose callsign begins JAS. Right now it scanned SYX, HGH, XIY and HAK.
This is a sample, not the whole fleet. Aircraft over oceans, between those airports, or outside volunteer receiver coverage will not appear here even though they are flying. A short list does not mean a small airline.
