The Box Man

A man abandons his identity to become a "box man," observing Tokyo from a cardboard box and recording everything. His solitary existence is threatened by a fake doctor who obsessively wants to become him, leading to a surreal and psychological battle over reality and identity. He is drawn into a manipulative game by the doctor and a mysterious nurse, blurring the lines between observer and participant, sanity and delusion, in a world where anyone can become a box man. AKA Hako otoko.
