Worldwide Rail Network Map
The Tokyo area is missing so many lines!!! .... or maybe there's just hard to see because for some reason they're in super non-contrasty colors.<p>My guess is, whoever made this, based it on the idea that trains and subways are different things. They aren't in Japan. For example the Mirai-Line (subway), The Tokyu Tokoyo-Line (train), Eiden-Fukutoshin-line (subway), Tobu Tojo Line (train) can all share the same cars and some "cars" run all 4 lines where other cars run just their own line.<p>I'm not sure what the definition of "subway" vs "train" is. In Japan it's certainly not "runs underground vs runs above ground". Even in NYC all the trains run for a long ways underground to get to Central or Penn station.<p>It's also certainly not "need a harder to get ticket than just use a transit pass" as pretty all the trains lines in Japan except for a few super express trains can be ridden just by starting with the cheapest ticket you got out of a generic ticket machine and paying the difference when you get off". So for example you can ride the San-Yo line 333 miles (537km) and it's just a normal hop on, hop off train. you don't have to go to some ticket booth/kiosk and reserve a seat like you would for say an ICE train in Europe or the bullet train in Japan
