Another thing to remember is that the Wii in one year in Japan will sell about what the Gamecube did in 5 years. That's a torrid pace and is going to have some weeks that are essentially breather weeks. Nintendo is very lucky that in these slow weeks the Wii is still selling over twice the competition and the DS dips just below 6 digits.
Nintendo has saturated Japan with Wiis to an degree unlike any other region. They've shipped proportionally over twice as many Wiis to Japan as the US (despite the N64 and GCN selling about 25% more porportionally in the US). The launch fever seems to have died down there, a record 10 months and a record first year later, so now it's time for the Wii to sell like every other successful system, on its games. Perhaps that's why Mario Galaxy and Wii Fit are going there first.
