Located in Kamikatsu—the first municipality in Japan to declare a Zero Waste policy—the Kamikatsu Zero Waste Center “WHY” is an environmental public complex dedicated to building a circular society. It fosters interaction and learning among producers and consumers, as well as between local residents and visitors. The facility includes the town’s only waste sorting station, where residents separate waste into 44 categories. It also features a reuse shop, office space, and an experiential hotel.
