Japan is pretty easy to understand, its a very aging society, and gamers of the current generations in Japan consist for the most part of people that have grown up and been gaming on consoles much more than on PC, so growth of PC gaming has been smaller and slower in Japan than in say the US. Console gaming is still the dominant form of gaming outside mobile gaming in Japan. So the fact that PC gaming today is far from being a real competitor to console gaming in Japan means Nintendo would naturally have less competition in Japan than in the US, and PS is also a much more popular brand in the US these days than in Japan.
