The only country that dominates OSes and processor chips, while it still has a significant share of RAM manufacturing is the USA (and the past few years has brought quite a few acquisitions in the RAMsector, if only to sop up excess capacity). BTW, the Japanese manufacturers like Sony and Fujitsu (and Casio, which is the OEM behind a lot of the more famous Japanese brands) got behind Crusoe Transmeta chips because they found them to be the best for notebooks and handhelds if you wanted a battery life beyond an hour, but even this new entry in the processor chip field is from the US. However, it looks like Crusoe may be history and if they can't come through with faster chips, the Japanese companies will have to go back to 100% Intel.
I've already explained on this list why Japan is not a contender in either processor chips or OSes (though such review of recent trade history was met with skepticism and ignorance). It goes back to the USA dictating to Japan from Reagan II onward.
Open standards Tron OS and chips designed in co-evolution with it were seen as a national security risk since it might take OSes and processor chips away from US dominance, therefore Tron OS and a Japanese processor chip for it were attacked as 'trade impediments' (US mercantalism pre-WTO).
Moreover, US investment in Korea and the US's own manufacturing more than met the Japanese challenge in RAM (though the disastrously high yen from 1994 had more to do with this than anything--and don't kid yourself, the high yen was US policy).
Manufacturers like Fujitsu and NEC stayed the hell away from it, since they saw what happened to Toshiba in the US (if you don't know what happened to Toshiba, review what happened when they sold milling technology that the Soviets allegedly put to use in manufacturing submarine propulsion).
Of course, there is a silent victory in this for the proponents of Tron--if you own Japanese electronics, it's embedded in many of them. It's the non-proprietary OS that is everywhere and it doesn't crash. It just isn't on your desktop or notebook PC.
Of course the US and its IT interests got blindsided by Linux, but this OS owes much of its success to the Internet, another phenomenon dominated by US interests. Also, Taiwan companies that no American could name have emerged as hugely rich and wildly successful in key niches in PCs. I own an NEC notebook. The chipset is Intel, the HDD is IBM Japan, the RAM is NEC, the LCD screen is Japanese (probably a company linked to Sharp), and the entire package was manufactured in Taiwan. Never thought I'd see the day when NEC read 'Made in Taiwan' on the bottom.
Certainly, Japan does not have any companies that are in the league of Microsoft, Oracle, Sun Systems, Intel, or even the revived IBM (which has a big presence here in Japan, since much of the technology to make notebooks and handhelds is here) etc.--though these companies are most definitely still sucking the steroids of inflated stock prices and years of never having to pay a dividend. Fujitsu comes close to being a total product and services company, but it's losing an awful lot of money right now.
