THE US cut was never on DVD only VHS, i am not even sure it got a laserdisc release and if it did it was pan and scan like the vhs and cut like the US release was always.
I wish there was a restored USA blu ray of the Japan cut from 1984 with English subtitles and a commentary track like Criterion does, but i doubt it will happen i doubt that the sales of the Godzilla blu rays are enough for anyone to pick up the rights.
