PSP is doing great in Japan! That's good to see actually, as it is a great portable device.
The reason I see it doing better than Nintendo in Japan is two things. First is the DS has saturated Japan to a point in which there are not very many new users buying the unit. Second thing would be that home consoles are just not as popular as they used to be in Japan. The Wii is selling up to 5X more consoles than the other consoles in the same time period, but is still being beat out by both the portable devices.
