YouTube I'm curious if you can get it in the US. Maybe on Satellite TV? Here in Hong Kong we watch most of the Muay Thai fights direct from Thailand down at the Thai food shop... they've got a hacked decoder box... connected to a sat dish and the stuff streams into a modified decoder some sort and voila!! The fights are on!! Not saying you should go that same route where you're at though... but I suspect the same thing is probably done with the K-1 fights. I don't actually know if they're televised live in Japan for the general non-special service subscriber.
funny thing espn shows this k-1 thing..all the time. but they must have only bought a few fights cause like for 3 years straight ...its the same exact fights hoost v sapp goodrich v mark hunt and the one were lebanar quits due to an arm injury.... and i love k-1 so i just try to pretend i dont know the outcome
