The huge underground parking lot at Tokyo's Kasai Station can hold about 10,000 bicycles. Each day, from very early until very late, workers, students and other commuters store their bikes at this facility. They included a cleaner heading to central Tokyo on the day's first train; two high school girls staying close to home due to the coronavirus; and a woman holding down two jobs to support her family. For three days, we asked parking lot customers about where they were going – and why.
