I'm currently planning a trip across Japan and when traveling between two cities (say Osaka and Tokyo for example) I've noticed that taking a domestic flight is much faster and even half the cost of taking the train. So as much as I wanted to experience Japan's famous trains on my trip I can't really justify using them extensively for longer distances. So why then are trains so popular?
