My Tomorrow, Your Yesterday (ぼくは明日、昨日のきみとデートする, Boku wa Asu, Kinō no Kimi to Dēto Suru) is a 2016 Japanese romantic drama film directed by Takahiro Miki based on the novel of the same name.

[2] On February 15, 20-year-old Takatoshi Minamiyama, a visual arts undergraduate and satirist in Kyoto, falls in love at first sight with Emi Fukuju while boarding a train for college.

After the two consummate their relationship on March 1, Takatoshi discovers Emi's journal that she purposefully left on the table.

Much to his confusion, Emi wrote them as if she races through time backwards: the first page is dated March 16, and the last February 15.

The next day, Emi reveals that she is a being from a world in which time runs backwards; what humans perceive as the future she already experienced as her past, and vice versa.
