The Busy Metropolis of Tokyo

Have you ever been on a train? If you have, you probably didn't have to be shoved inside just so the doors could close. In Japan, this is what happens. Japan is extremely overpopulated, and just everyday life is hard to get through without being squeezed next to a bunch of strangers. People are actually hired to push people into the subway so that they can fit. And could you imagine water parks? there is one where there is a wave pool, and you cannot even see water. All you can see is people squeezed into the wave pool and moving up and down. How would they get out? I challenge you to find more places where there is an extreme population.
