Article here. The article is basically about how all the high-tech stuff like giant robots and computer toilets is in Tokyo, while the rest of the area uses pretty basic technology for most things. I would say it kind of reminds me of other countries that put on fronts, but then again with how prevalent technology is in a lot of anime it seems that many people enjoy the idea of it, even if a technology isn't available in their area they still know of it since it's a Japanese thing and incorporate it into their works that are focused on entertainment... so I wouldn't call it a front, simply that the technical stuff is more interesting and thus presented and discussed more (also pride). Anyways the article also goes into how the Japanese use cell phones as portable computers much more than other people do... when I was a teen I was all up in that RPG Maker and M.U.G.E.N. stuff, and a lot of the sites I visited for both of those really seemed formatted more to fit a cell phone than a PC screen.
