> … near to Tokyo station. Longest at the moment … 2.7km. I walked that route once, about twenty-five years ago. We had had an unusually heavy snow for Tokyo and I needed some exercise, so I took the subway to Otemachi and walked underground to Higashi Ginza and back. The areas around Shinjuku and Osaka stations also offer vast, mazelike underground pedestrian networks. I used to pride myself on knowing the entire Shinjuku system, but it has expanded since and now I might get lost. After many trips to Osaka, I feel I know all the nooks and crannies of the network there, but it has probably expanded in the past couple of years, too.
