The Girl Who Leapt Through Time
According to the scholar Ulrich Heinze, the novel represents the first fully formed version of time travel as an exploration of self. In contrast to other time travel stories up until the 1960s which typically involved expeditions, "The Girl Who Leapt Through Time" limited the time jumps to a short period to examine adolescence. It was also an early example of a time loop narrative, anticipating plot elements of the later Hollywood film "Groundhog Day" (1993).
