As predicted in a news post not long ago, Square Enix have released Rise of Mana on the Japanese App Store. We've got a thread for it in our forums if you want to join in on registering a Japanese iTunes account and trying to figure out how to play the game which currently features no English translation options.
If nothing else, the trailer looks really cool, and while it's both really hard to play and figure out how the free to play elements work if you don't know how to read Japanese... Let's keep our fingers crossed their's something to the European Rise of Mana trademark and an international release is coming? Maybe? Either way, if you've got a Japanese iTunes account, hit this link and give the game a shot.
