Following up on Dave's great idea of having a NYC Subway Map on your PSP, I thought a Tokyo Subway Map for the PSP would be beneficial to anyone thinking about visiting the big city. I'm hopeing Tokyo Metro isn't as hard up for licensing fees as the MTA.

And just because I have a slight preference for Osaka over Tokyo [although they are both great places], here's an Osaka Subway Map [548 KB] as well.
