You might have noticed a serious dearth of Disney characters speaking in Japanese on Joystiq lately -- we sure have, and it's just tearing us to bits inside. Thankfully, Square Enix seems to have taken note as well, recently updating the Kingdom Hearts: Birth by Sleep website with more than just wallpapers (though you'll find three of those on there, too). How about the entire seven-minute-long trailer from Jump Festa 2010?
We've embedded it above, though if you're dying to know what the people in it are actually saying, we suggest you check out the full translation right here. And then, once you have it in English, you might ask your nearest Kingdom Hearts fan to translate further.
