There is serious talk in the Tokyo Metropolitan Government of running the city managed subway systems Toei Chikatetsu（都営地下鉄) 24 hours a day when Haneda Airport opens to more international flights later this year. You might think of Tokyo as the city that never sleeps but in fact all public transportation stops around 1 am. This forces any one living far from the city to head home before midnight or be stranded until five or six am. However, with flights arriving into Haneda at all hours of the night–a lack of any other transportation other than expensive taxis is sure to go over poorly with much sought after tourists.
At the same time, merchants in Kabukicho, the former red-light district of Tokyo, located in Shinjuku are pushing to allow the area to be designated a special region where all businesses can stay open 24 hours a day. Currently, host and hostess clubs are forced to shutter their windows at one am. They are circumventing the laws by transforming the places into “girl’s bars” or “boy’s clubs” after hours, with stand up counters where customers can order drinks,–which makes them “bars” instead of cabarets, technically. Tokyo has a fair amount of latitude in how they run their own subway system, and while the 都営地下鉄 (toeichikatesu) routes are limited, if they run 24 hours a night there is a good chance they will become the last resort of the night owls and newly arrived passengers at Haneda. Longer hours should translate into more employment for the locals–and the cops as well.
