Enormous floats called neputa paraded through the streets are the highlight of Hirosaki Neputa Matsuri in Hirosaki, Aomori Prefecture. The floats are decorated with vibrant images painted on washi paper. Some floats feature wireframe 3D figures. For most of the floats new art is produced every year, and preparations begin months in advance. This 300-year-old tradition began as a way to ward off drowsiness and keep people focused on farm work in the heat of summer.
