I'm not sure about the exact numbers, but 'Tokyo Metro' is only a small part of the Tokyo train network.

There is also Toei Subway, JR East trains, Minato-Mirai, ...the list goes on. 2100 may work for the entire metropolitan area of greater Tokyo.

In any case, the city is massive, extremely well connected by public transport, and services millions of people daily without delay.

Wikipedia (https://en.wikipedia.org/wiki/Transport_in_Greater_Tokyo#Rai...) says "There are 882 interconnected rail stations in the Tokyo Metropolis, 282 of which are Subway stations, with several hundred more in each of the 3 surrounding densely populated suburban prefectures. There are 30 operators running 121 passenger rail lines (102 serving Tokyo and 19 more serving Greater Tokyo but not Tokyo's city center itself), excluding about 12 cable cars."

I could probably believe the 2,100 number if you include all the surrounding prefectures that are in the broader Tokyo area, and if you count stations multiple times for each railway operator services them (it's not uncommon for a single station in Tokyo to be run by three or five different companies).

> There are around 136 individual rail lines in the Greater Tokyo Area, and between 1,000 and 1,200 railway stations depending on one's definition of the area.
