Public transportation in Tokyo is arguably the best in the world. Conditions are not always comfortable, but 99 times out of 100 you will get to your destination on time. On the occasions that you don’t it is because some poor soul chose to end it all in the manner which inconveniences the greatest number of people possible – but don’t worry, his or her grieving next of kin will more than likely have to pay for it with a $30,000 fine.
Anyway, I digress, that is about trains and this is about subways. Most of them are accessed via the same stations – most of them only via stairs. The subways of Tokyo, which are run by Tokyo Metro and Toei, shuffle more than eight million passengers per day between 290 stations across 13 lines. As you can see from the model, there is quite a bit of overlap. The newest lines are the deepest, with the deepest station (Toei Oedo Roppongi) sitting 40 meters below the ground. [Japan from Inside]
