So many companies do some many things these days in so many locations who knows what studio will contribute to a game so you can't just lump all Sony or Nintendo things into Japan. I was going to try and argue China just because of how much of it is physically made there even if it's not programed there. Or argue just California :P since there are plenty of studios here and silicon valley.

I think it's safe to say that side from Retro and NST pretty much all of Nintendo's games can be attributed to Japanese development. The hardware probably involves a bit more international co-operation from what I've heard. As for Sony, I'm not really an expert. I understand they have several studios abroad.
