Idk if this is a viable idea or not, but it would be really cool, for curiousity's sake if nothing else, to have goole translate or something rigged through the shout feature. to show NA users what the JP are saying & vice versa (not that they'd prolly care).
Like I said I have zero idea on if this idea is even feasible, ect. so please forgive me if it sounds stupid.
OK
Well you can copy and paste from the shout page into Google Translate.
It's more steps than what you're suggesting but it works. :)
