Even if they hold little interest in PC gaming, PCs are as popular over there as in any developed country. I guess they simply don't play games on their PCs, which is probably due to the inability of the Japanese industry to produce games for PC - because of fear of piracy? Who knows?

One thing that left me wondering about the article was how it said many Western games get a classification similar to adult games (forbidden from under 18 years, I reckon) and thus major retailers don't carry them. Getting that classication in itself is perfectly natural, since having a look at your game shelf reveals games like Witcher, Dragon Age, Fallout, etc are all for adults only. However, for shops not to sell them (or hypothetical similar Japanese games, if nobody buys Western games) because of that is incredibly strange when you also say adults are used to gaming to pass time during long commutes. So, despite gaming a lot, adults in Japan are restricted to games meant for kids? Strange place indeed.
