uh its not like the icons are "region based" well not all of them anyway. For example the comic readers and the comics you get is defined purely by the region on your PSN account. If you make a jap account oyu can download the jap comics and read them via digital comics.

As for playstation spot that was for like some partts of asia and only if you are in those parts of asia will you be able to use it. As the event that happen for it go on it those countries only. Last time i check playstationspot didnt even work anymore.
