In This Corner of the World

One day in 1934, Urano Suzu, a young girl living in Eba , Hiroshima City, is kidnapped while on her way home. However, thanks to Shusaku, a boy who was captured earlier, she manages to escape. Suzu returns home safely, but the events of the day seem like a dream. Time passes and it is the autumn of 1943. Suzu is helping out at her grandmother Morita Ito's house with her younger sister Sumi. Her aunt informed her that someone is at their house in Eba who wants Suzu as a bride. While rushing home, Suzu meets her childhood friend Mizuhara Tetsu (Murakami Nijiro), who has joined the Marine Corps . Suzu is confused as she thought Tetsu is the man. Meanwhile, at Urano household, Hojo Shusaku and his father Entaro are waiting for Suzu to return home. Suzu's father, Urano Juro, and mother, Kiseno, are embarrassed and continued their conversation. Shusaku says he had fallen in love with Suzu before, but when Suzu sneaks a peek into the house, she has no recollection of him at all.

It's been days since Suzu (Matsumoto Honoka) married Hojo Shusaku (Matsuzaka Tori). The Hojo family home is located on a mountain with no running water, so Suzu's daily routine is to fetch water from the community well. Her next-door neighbor, Kariya Taki (Kino Hana) , tells her about the neighborhood. She's gradually become acquainted with the neighbors, like Taki's daughter, Sachiko (Ito Sari), and Domoto Shino (Tsuchimura Kaori). Suzu begins to realize that she has become a bride. Suzu wants to learn the family customs from her mother-in-law, San (Ito Ran), but is reluctant to ask because San has a bad leg. Meanwhile, San also does not interfere with the housework. One day, Keiko (Ono Machiko) returns to the Hojo household with her daughter Harumi (Inagaki Raizumi). Keiko tells Suzu that she will take care of the Hojo household chores and that she should go back to her parents' home. Suzu decides to return to her parents' home one month after getting married.

One night in June 1944, the first air raid siren sounded in Kure. As the city gradually became more war-torn, the Hojo and Kariya families decided to jointly dig an air raid shelter. Suzu couldn't help but find Shusaku cool. Her sister-in-law Keiko (Machiko Ono) and Sachiko Kariya (Sari Ito) were not happy with this, and being harsh towards her. Then Suzu learned that Shusaku had another marriage proposal. Suzu accidentally drops some sugar into a water jug ​​while observing ants with Keiko's daughter, Harumi (Inagaki Raizumi). Sugar is a luxury item that will be discontinued from rationing starting in August. Her mother-in-law , San (Ito Ran) gives Suzu some money to buy sugar at the black market. While Suzu was walking home from the black market, she suddenly finds herself lost in an unfamiliar place. She asks passersby on her way home, but no one knows where she is. At a loss, Suzu is approached by a woman named Rin (Nikaido Fumi).
