In the US, that would never fly. The people that are willing to pay for the features need them to work in all the "large metro areas", which doesn't mean "Manhattan" but rather "suburbs of Phoenix" and so on. This makes infrastructure roll-outs very expensive, and it's why they never happen.
(Incidentally, people in the US and Japan have similar commute times, but the population density in the US goes down a lot faster as you move away from the city center. In Tokyo, it's densely packed until you get to the mountains.)
Population density has its advantages; look at everything Japan has that the US doesn't (100Mbps internet for $20/month, interesting cell-phone features, amazing rail systems), and population density explains it all. But then, they don't have 5 bedroom houses for $150,000, either.
I'm personally I strong believer in the free market, however sometimes the market is too short-sighted to make investments that will benefit society in the long run. Infrastructure and education are good examples of that. It's hard for private investors to get good ROI on things like roads, IT-networks and schools because it takes many years to get any return and it's hard to charge people as much as it actually benefits the public.
I saw and interview with Bill Gates where he basically said that this was his rationale behind the Bill and Melinda Gates Foundation. The market simply doesn't maximize the amount of lives saved per dollar and you need non-profit organizations to do that.
Although, now there's one cable ISP that offers 110/5Mbit/s for around 70 Canadian dollars per month.
That's basically the only operator interested in advancing things.
And that is, according to this article, exactly their problem: the Japanese are just too focussed on features.
What I meant to say earlier was that this look could appeal to some people in the west too. Some people just want something that looks different than the iphone or razr. I know my wife loved the cute pink clamshell phone she had in Japan (that I spent days trying to jailbreak afterwards).
Sounds like a feature to me...
-The internet browsing thing is basically because a lot of Japanese websites have a "mobile mode", ultra simplistic layout as an option. It's not really a phone feature.
-TV receivers in mobile phones require a special signal to be sent for them (the currently available models can't deal with normal dvb-t, for example [AFAIK]), and there are different standards in use for this in different parts of the world. And well, it just isn't a terribly useful feature in the first place.
-Push email is used to replace SMS, which is pretty cool but that'd require a data plan over here.
On the other hand, Japanese phones generally lack stuff we take for granted: t-9 text input, spelling dictionaries, they use a slightly different network standard (FOMA vs 'normal' 3G),... all of which are possible to fix, of course, but then, it wouldn't be that hard for the competitors to copy their good features either.
I'd say that if Japanese phones ever become a hit in the west, it's because of the cool and different designs rather than features.
