Trailer for Hesomori.
Five young friends discover a network of time travelling tunnels that take them to different eras in Japan. Hesomori picks up their story 40 years later. As adults, Satoshi has watched his childhood friends leave their rural village to become professors, hotel managers, and other urban jobs. Staying behind, Satoshi runs the traditional paper mill of the village and struggles to make ends meet in modern times. Strange things start to happen when a nefarious developer with connections to the tunnels swoops in and makes the region a tourist spot. Satoshi and friends are called into action as guardians of the tunnels when the developer discovers a samurai who wanders in from another era.
