In a small mountain village far away from the metropolis, lives Mitsuha Miyamizu (voiced by Kamishiraishi), a high school girl from a shrine maiden family. School and family issues have already troubled her, and the strange events that have happened recently have left Mitsuha confused. I don't know when Mitsuha has become a high school boy living in Tokyo in her dreams. There are strange classmates and friends, kind seniors and bustling streets, everything is so tempting and real. On the other hand, Tachibana Taki (voiced by Kamiki Ryunosuke), a high school boy living in Tokyo, always comes to a strange mountain village in his dreams and lives a new life as a girl. Perhaps influenced by the mysterious comet, Tachibana and Mitsuha exchanged identities in their dreams. They experience each other's lives from the perspective of others, during which there is anger, laughter and warmth. But the two don't know that behind the identity exchange lies a major and heart-wrenching secret... This film is the box office champion of Japanese local films in 2016.
