I haven't been to Tokyo yet, but in Munich you don't just have a shop or two, some of the more central stations (Stachus, Marienplatz, Hauptbahnhof, Sendlinger Tor) have small shopping centers in the mezzanine level. While renovating these during the last years, they have tried to optimize (i.e. increase) the surface usable for shops. But it's still pretty unfair if you think about it: having a subway system is a major plus for a city, so landlords get to collect more rent (generally, and even more if the building has a subway station nearby). So it's only natural to ask them to pay slightly higher taxes to help finance public transportation. But subway systems still have to justify why they are cross-financed using tax money...
