The Japanese rely on rail transportation more than most, with the busiest of Tokyo's many large stations handling around 2.7 million passengers a day, commuting to work and school. These stations contain malls that offer everything from convenience stores to cafes and bookstores, and which continually add new services to keep pace with modern life. We visit a clinic, accessible from the platform to provide consultations for commuters on the go, and a daycare center run by a rail company for working parents.
