I may have this whole "free pass" thing mixed up. I've seen it mentioned here and there on the internet that tourists who are in Japan for 2 weeks can get a free pass for the bullet train. However, I can't find any solid details on how this actually works or how to get the pass. Am I completely misreading the idea of a free pass? Is it actually a pass you PAY for, but once you have it it's free to take any train once you've got the pass? Or is there some kind of special ticket only available for tourists - as if it was some kind of initiative to promote tourism throughout the country? Any clarification is much appreciated.
