Japanese internet speeds?

[ishqabdi628]

A friend of mine spent some time in Tokyo recently and was telling me how ridiculous the internet speeds there are and how it's free to everyone on any device. He said he used one of those speed testing sites and the timer ran out before the full speed could be calculated. It would explain why internet sites like Tudou and Youku don't work properly here. I was just wondering if anyone knew the specific type of technology in place in Tokyo.
