Japan and CS

I've had a short conversation with a friend about Japan's position in CS recently. Japan has always been known to be on the bleeding edge of technology, after doing a little reading it's clear that they basically just focus on electronics, AI, aeronautics, among others.

Japan has the fastest super computer right now as far as I know, that says SOMETHING about their intentions for CS but I don't see much else coming from them. My prediction is that they're just not focused on improving it as much as other technologies. Any thoughts?
