Wii MotionPlus surpasses 600,000 units sold in Japan

We’ve already mentioned just how well Wii Sports Resort has performed in Japan, which comes packaged with the Wii MotionPlus accessory. To recap though, the game sold 150,000 copies on its first day and then 350,000 over a four day period. But what about MotionPlus as a standalone product? On its own, the peripheral is up to 290,000 units sold based on its first shipment. Combining that with the Wii Sports Resort bundles, MotionPlus has already exceeded 600,000 units in total.
