It is. I don't know why Japan's being counted differently. @OP NTSC |
ntsc and ntsc-j are different, from a standards perspective, ntsc-j uses the same black level and blanking values, where ntsc uses higher black level than blanking level, from a broadcast perspective they use entirely difference frequencies.
And of course, region locking prevents ntsc and ntscj games and systems running in each other.
