I know you guys linked to the japanese wiki site for these, but I thought it might be nice if they were translated into numbers because it kinda bothered me tryin to figure out which symbol was which. So below I've put the code into numberic text form. It should be self explanitory. I'll also try to put on there what they unlock. Although I don't remember number 2 and 4 are kinda fuzzy, I don't remember those too well. ok, anyway, here
