I ask in the spirit of aircraft spotting and would also prefer those with live ATC feed, like Osaka. As of now, the visual quality at is blurry and hazy, but perchance this is due to low visibility and bad weather?

On the side panel of that, I clicked on another for Narita, but this one doesn't capture the (active) runways: http://www.webcamhopper.com/ust/narita.html

Is there an efficacious, systematic method to find all such webcams for substantive airports worldwide? Do such manifests or records already exist? I tried http://forum.flightradar24.com/threads/352-Planespotting-All-Live-Airport-Video-Webcam/page3 which cites http://airportwebcams.net/, but these are NOT streaming and realtime.
