The setting is Gujo Hachiman, Gifu Prefecture, known as the "town of water." It has streams so clear that you can see the bottom, and canals and springs that crisscross the community. People here have always treated the water with respect. When YouTube star Haruka visited the town, she turned her camera on the residents and the waterways to offer an "on-the-spot" report from the perspective of an urbanite. Then, a strange fishlike man leads her on a chase and offers an important lesson.
