Manga is generally released in a mirrored way over there? Over here, most comics are right to left, because of purists and as a commercial gimmick, sort of like"ohh, look, it's opposite" - but mostly to keep faithful to the original, sometimes the contract made with the japanese publisher asks for it to be published this way (when I grab some "ocidental" comic book I sometimes forget about it and look at the last page first).
