How to explore Tokyo

The fisrt think is to get familiar with the Yamanote green train line, there are 30 operators running 121 passenger rail lines across 882 interconnected rail stations in the Tokyo Metropolis and if you got a few days getting lost is not a good option.

This is a live map of tokyo transportation if you would like to see how crazy is it.

One unique thing about tokyo is the music of each train station. Listen to the city's soundscape; it's usually quiet inside the train, but be sure to keep your ears open for the distinct jingles at each station.
