That's nonsense. JAST didn't censor anything at all. They use an all-ages port of the game that was adapted by the company itself (Xuse). I definitely agree with the dubbing comment (there are a very few exceptions where the dubbing was done exceptionally well), but given the choice to (legally) play Aselia in English censored or not at all, I choose the former. The game itself doesn't really lose anything, unlike other H titles that have been censored.
You have to remember that scenes in the original Aselia release was WAY over the line of what US laws would allow. Not market. LAW. Raping
