User blog comment:Kisukeiscool100396/Name romanizations in WSJA come from Tite Kubo himself/@comment-1429792-20121029192638

Good spot. Quiet happy to hear that. It was plain to see that they didnt happen on Quilge by chance. It means we still have to be cautious about these spellings when they first appear though as shown by Hashvalt/wald. Might want to hold off on changing any names for a few weeks after the first time a name is mention before it is safe, or rather until it has appeared in a few chapters. No telling how late a confirmation could come though
