In 1991, Takaki Tōno quickly befriends Akari Shinohara after she transfers to his elementary school in Tokyo. They grow very close to each other due to similar interests and attitudes such as both preferring to stay inside during recess due to their seasonal allergies. As a result, they form a strong bond which is shown when they speak to each other using their given names without any form of honorifics as that is a sign of deep friendship and familiarity in Japan.
Right after graduating from elementary school in 1994, Akari moves to the nearby prefecture of Tochigi due to her parents’ jobs. The two keep in contact by writing letters but eventually begin to drift apart. When Takaki learns that his family will be moving to Kagoshima on the other side of the country the following year in 1995, he decides to personally go see Akari one last time since they will be too far apart to see and visit each other once he moves. He also writes a letter for Akari to confess his feelings for her. However, Takaki loses the letter during the journey and a severe snowstorm delays his train for several hours. When the two finally meet late that night and share their first kiss, Takaki realizes they will never be together. They find a shed to spend the night in due to the severe snowstorm and fall asleep after talking late into the night. Takaki departs from the train station the next morning and the two promise to continue writing to each other. As the train rolls away, Takaki decides that the loss of his letter is not important anymore after the kiss while Akari silently looks at her own letter addressed to Takaki which she decided not to give him.
