show us that Wii Fit is popular among Japanese gamers. To give you a sense of just how well it's doing, though, Enterbrain recently reported that two million copies of the fitness title have been sold in Japan. Matched with recent reports of six million Wii consoles being sold in the region, that means every one in three Japanese Wii owners bought a copy of Wii Fit.
It hasn't yet caught up to its Nintendo cousin, Wii Sports, which has almost reached the three million mark. Yet, keep in mind that 1) Wii Fit was released a year after Wii Sports and 2) Wii Fit is a lot more expensive; it costs more than a usual Wii game, while Wii Sports costs less than the standard. To throw in another interesting comparison, Media Create sales indicate that there are almost as many Wii Fit owners in Japan as PS3 owners (with the PS3 currently having a 50,000 unit edge).
While we find it unlikely that Wii Fit will hit the same one-in-three ownership ratio in Europe and North America, we have little doubt that the exercise software will do well in those regions, too. Let it be said that Nintendo definitely understands the casual market.
