The *jidohambaiki* is a key feature of the Japanese landscape, seemingly on every city street corner, a staple on train platforms and encountered in such unlikely places as shrines and mountain paths. In Tokyo, a city that is machine for living—or rather working, it’s a symbol of convenience. Here every other street corner houses a 24-hour convenience store, there are 24-hour postal sevices, and 7-days-a-week delivery services working late into the night, their deliveries timed to 3-hour periods. Tokyo is the city of capsule hotels and all-night comic book cafes, of train-platform noodle bars and station lockers. These facilities and more have been devised to help the city’s salarymen and working women function more efficiently, keeping the gears of the city turning smoothly.
