Well... I always root for the underdog (consumers in this case). All these youngins moving to Japan now have it SOOOO much easier.
In '98 when broadband was first introduced, NTT sat on the technology, swearing they'd skip DSL and go straight to Fiber. Why not? At roughly 3 cents per internet minute, they make a fortune over the next 5 years it takes to put fiber in the home. They own every phone line in the country anyway. Cable wasn't widespread enough to be a competitor. So, all was well in the NTT world. Consumers paid big bucks for crap internet connectivity -- a huge detriment to the country, keeping many Japanese 'offline' for a long time. Eventually, one of their big wigs quit, formed Tokyo Metallic (東京めたりっく for those that want to google it) sued NTT (and won) and basically single-handedly introduced ADSL to Japan. It's a very interesting story.
There's also the age old story of foreign competition trying to enter the Japanese markets but not being able to compete w/ NTT's screwjob prices. When NTT tried to buy a major internet backbone in America, the FBI intervened and promptly told them to go **** themselves. The official 'reason' was b/c NTT was 58% government owned, and the US couldn't allow another government to have access to so much information. But I think the real reason was to teach them a lesson. The government eventually eventually sold off enough shares to be a privatized company. I've not been able to find either of the stories online... I saw them in old Tokyo Classifieds though.
Finally, since NTT was a monopoly, they invested 0 yen in customer service. Their helpdesk is a joke. A bunch of oba-sans that have no clue what they're talking about. I berated one of them for hours until she finally gave in. In short, NTT sucks, and NTT DoCoMo is "in the family".
