Tokyo Metro is somewhat old, but it has a dense network and convenient transportation. It serves the urban rail transit system in Tokyo metropolitan area and its surrounding areas. At present, there are 13 lines in total. Tokyo Metro opened the section from Ginza to Shallow Cao Temple in December 1927. It is the earliest Metro City in Asia. The Tokyo Metro system has 285 stations with a total length of 312.6 kilometers and an average daily passenger flow of tens of millions of people. It is the largest metro system in the world. But now there are more than ten metro lines in Beijing, Shanghai and Guangzhou, no less than the Tokyo metro, and the facilities are new, the design is more modern, simple and fashionable. So, by contrast, one is like an old man in his twilight years; the other is like a young man in his prime.
