Taki wakes from what seemed like a very important dream. But in an unfamiliar room and not in his body... but that of a girl! On the other hand, Mitsuha, a teen girl, is tired of living in a mountain village. She pleads to God "Please, let me be a handsome Tokyo boy in my next life!" The next morning, Mitsuha awakens as a high school male. Based on information around her, she learns whose body she inhabits. His name is Taki. The two have switched places! When they wake up again, they’ve returned to their former selves. But sleep brings the body swap again and again. Mysteriously, the pattern continues daily. The two fumble about, unaccustomed to each other's bodies, but start communicating by memo. As they awkwardly overcome one challenge after another, a bond develops between the two - one that evolves into something more romantic. However, there's something they still don't know... The unexpected is about to be revealed.
