For laptops, the biggest brand (other than apple) is probably Asus (based on retail floor space ;-) ). Sony, Panasonic, Fujitsu and Toshiba pretty much share the rest. Toshiba is apparently exiting the market soon, though. From my perspective, it seems that the market is split between very high end, large format, desktop-replacement machines and tiny machines. There is not very much in the middle. I live in the countryside, though. It is very possible I don't see the interesting models where I live.
When I worked at a high school, all of the machines were actually Dell. It surprised me greatly.
One thing that most people don't realise is that Japanese electronics are expensive compared to the rest of the world. If you have high end purchases (like a computer), you can fly to Korea and the money you save will pay for the flight, easily. Especially with the insanely high yen, American machines are also a pretty good deal.
I like to support the local economy, but when Toshiba exits, I might be stuck finding the kind of machine I like to use.
Edit: I take it back. Should have did some poking around before I posted. NEC sells the Lavie model in Japan, which I have definitely seen. Looks like they are filling in that middle tier that I like as well. I wonder how well it supports Linux...
This is pretty interesting because my experience has been that electronics were pretty expensive in Korea, as well. When my wife's laptop died while she was working in Korea, I ended up bringing her a new Samsung laptop from the US on my next visit because it was considerably cheaper here than buying it there.
The Panasonic models still have optical media. I can't think of a single western laptop that has a Blu-Ray burner in it. There might be some gaming laptops with that, but they would probably be 17 inch monsters and not extremely lightweight laptops.

Windows still reigns absolutely supreme in native companies, though.
