As far as timeliness - Trains every five minutes on the dot, except for rush hour, then they come every two minutes. The subway runs late SO INFREQUENTLY, that if you are one minute late, there will be a rail officer at the exit to give you a note telling your employer the subway was behind - otherwise nobody believes you. I heard somewhere that there are on average perhaps three to five trains a year that were over one minute late, and most of them because of an earthquake. As far as price goes - yeah, its a bit more expensive, than some places, but it all depends on how far you are going. Its still 10 times cheaper than a cab in ANY large city. It is possible to get from one end of the city to the other in 15-20 minutes, for $12. A small price to pay for such an amazing feat. There is very little vandalism, and there are no police officers or security in the stations. There is no crime in the subway. Plus - I can't think of another subway system with as many stations... Tokyo Subway map Â Plus its only really crowded from about 6am-8am and from 5-7pm... other than that, most lines are actually reasonable. Oh and perhaps the Tokyo Subway system seems crowded because - there are 30 million people who live in the metropolitan areas of Tokyo.
