Getting Around in Tokyo

I made the horrific choice of taking the cabs here in there while in Tokyo because they are undeniably much more convenient. However,  their subways are just as efficient. It can be quite confusing at first; but it's actually very easy to use! It's reliable too. The only downside I can think off, stations can be quite far. But then again, the norm is: everybody walks! I really wish he had the same system here in Honolulu.
