> Aside from Matz, has Japan even produced any really notable software or operating systems?
The NES, the MSX, The FM-Towns, Sega Master System, Megadrive, Dreamcast, the SNES, Mario, Contra, Starfox, Golden Axe, Thunderblade, Outrun, The PSP, The Playstation, PS2, PS3.
That's just in one industry (gaming). Of all of those the only ones that weren't significant out of Japan were the FM-Towns and MSX. The MSX was the biggest single threat to 8-bit computers in the early to mid 80s not because of it's power, but because it was a licenced standard (with OS software admittedly written by Microsoft, thank goodness they never got a hold on the OS market!)
