Given Tokyo's huge number of independent transit operators, there's no real authority to grant any "exclusives."

By the same token, getting real-time info out of all of these operators would seem a huge task...

But given the nature of Tokyo transport, it's hardly necessary in most cases anyway—everything runs extremely frequently, and pretty much exactly on time (so scheduled times are usually all you need), and the system's emphasis on rail over buses means that variability due to traffic conditions is rarely a concern.
