Nakasu in Fukuoka Prefecture is one of Japan's largest nightlife districts. Tucked away among the 2,600 dining and entertainment establishments, here is a daycare center open from 7 a.m. until 2 a.m. the next morning. During the day, workers at the nearby office district drop off their children, while in the evening a steady stream of parents who work in Nakasu leave their kids in its care. The center has a busy period around midnight as parents pick up their children. They include an elegant restaurant manager wearing a kimono, and single parents working hard to earn enough to raise their children. For 3 days, we listened to the parents and children whose lives are supported by this daycare center.
