"yes, but:" the lines don't provide the same service along their path. Just because you can get from some point in Tokyo to NRT airport on 3 different services doesn't mean that these 3 services are competing on everything else. Same for the different lines and companies in other places. I would actually consider this an odd example of "long-range" transport.
