Listen, when a place is so massive that you need to ask FIVE different people for directions to find your Shinkansen (bullet train), you know you're dealing with something special. Tokyo Station isn't just big - it's a labyrinth disguised as a train station.
Think of it like a small city that happens to have trains running through it. Sure, it's got all the fancy architecture and endless shopping options you'd expect, but what really stands out is its ability to make you feel completely lost while being surrounded by hundreds of people. The station's got more restaurants and shops than some small towns, which is great... if you can find your way back to them twice.
Pro tip: Give yourself WAY more time than you think you need if you're catching a train here. And don't feel bad about asking for directions - even if you have to ask five different people like we did!
