The basic concept is that of a puzzle-action game, as you take on an AI opponent to match plates and sushi types, making it a quickfire matching game. Controls are on the touchscreen, and naturally you want to work up combos and powerful moves; it's time pressured, too, as you have seven seconds to create and use a combo. There'll also be multiplayer in addition to the standard single player story.
It's not entirely clear whether it'll be an eShop or retail game (Nintendo's official sites don't clarify as yet), but it's still relatively early in development.
