Recently nabbed myself one of these. 'Tis the English version (though I wouldn't mind a Japanese one, seeing as my Pandora Hearts artbook is in Japanese), but content wise, nothing should differ. The covers are a bit different, with the Japanese book having an extra cover page, resulting in the cover looking like this.
Those who also follow my photoblog would have seen this a wee bit earlier. I put a slightly brighter photo of the same thing up there yesterday.
