Their father left home fifteen years earlier with another woman, and their mother later remarried and moved away; the grandmother who raised the three sisters has also died. News of the father's death reaches them, and at his funeral they meet Suzu, their shy junior-high-school half-sister, whose own mother has died and who has no comfortable place in her [stepfamily](https://www.edgepedia.org/stepfamily). Sachi invites her to live in Kamakura, and the four begin a new life together in the old house.[1](https://www.fujitv.co.jp/movie/01movie/20150000_08_M00.html) • [10](https://www.justwatch.com/jp/%E6%98%A0%E7%94%BB/hai-jie-diary)\n\nThe sisters have distinct working lives: Sachi, the eldest at 29, is a nurse at the local hospital; Yoshino, 25, works at a bank and is promoted from teller to loan manager during the film; Chika, 21, works in a shoe shop. Suzu is 13 when she joins the household, which the sisters jokingly call an \"adult dorm.\"[2](https://www.chelmsford-filmclub.co.uk/wp-content/uploads/2017/03/Our-Little-Sister-CFC-film-note.pdf) • [7](https://www.independentcinemaoffice.org.uk/films/6712/)\n\n## Production and adaptation\n\nKore-eda adapted Yoshida's long-running manga, which had been serialized in *Monthly Flowers* since 2006 and won the Manga Taishō 2013. The adaptation changes characters and story elements from the comic; in his Cannes festival statement, Kore-eda explained that he added conflict absent from the original, asking why none of the sisters bully their little half-sister in the graphic novel and noting that the story lacked elements such as Suzu running away from home after trouble with her older siblings.[4](https://eiga.com/movie/80446/) • [11](https://cdn.festival-cannes.com/media/uploads/2023/03/38012.pdf) • [12](https://eiga-square.jp/title/umimachi_diary)\n\nKore-eda also drew on research for the script, saying he interviewed women who were actual third or fourth sisters and reflected what he learned in the film.[13](https://www.waseda.jp/inst/weekly/features/specialissue-koreeda3/) The film was produced by [Fuji Television](https://www.edgepedia.org/fuji-television), Shogakukan, Toho, and Gaga, with production by FILM; music was composed by [Yoko Kanno](https://www.edgepedia.org/yoko-kanno), and cinematography was by Mikiya Takimoto, who had also shot Kore-eda's *[Like Father, Like Son](https://www.edgepedia.org/like-father-like-son)*.[1](https://www.fujitv.co.jp/movie/01movie/20150000_08_M00.html) • [11](https://cdn.festival-cannes.com/media/uploads/2023/03/38012.pdf)\n\nThe film's length is listed as 126 minutes by Fuji TV and eiga.com, and as 128 minutes by WOWOW and the Cannes festival dossier.[1](https://www.fujitv.co.jp/movie/01movie/20150000_08_M00.html) • [4](https://eiga.com/movie/80446/) • [3](https://www.wowow.co.jp/detail/108319) • [11](https://cdn.festival-cannes.com/media/uploads/2023/03/38012.pdf)\n\n## Setting and style\n\nThe story is told largely from Suzu's point of view, with Kamakura's four seasons woven through the imagery: summer ocean light, autumn foliage, a tunnel of cherry blossoms, rain-season hydrangeas, and summer fireworks. Critics noted the film's episodic structure, reflecting its origin in monthly manga installments, and its visual control, including deep-focus compositions that reviewers compared to the style of Yasujiro Ozu.[3](https://www.wowow.co.jp/detail/108319) • [2](https://www.chelmsford-filmclub.co.uk/wp-content/uploads/2017/03/Our-Little-Sister-CFC-film-note.pdf)\n\n## Reception and awards\n\nThe film competed for the [Palme d'Or](https://www.edgepedia.org/palme-dor) at the 2015 Cannes Film Festival.[8](https://www.imdb.com/title/tt3756788/awards/) At the 2016 Awards of the Japanese Academy it won Best Film, and Kore-eda won Best Director, with additional top awards for cinematography and lighting; the film also received 5 wins and 13 nominations at the Japanese Academy overall.[12](https://eiga-square.jp/title/umimachi_diary) • [6](https://www.metacritic.com/movie/our-little-sister/) [Suzu Hirose](https://www.edgepedia.org/suzu-hirose) won the Hochi Film Award for Best New Talent in 2015 and the Kinema Junpo Best New Actress Award, while Kore-eda was named Best Japanese Director by Kinema Junpo readers.[8](https://www.imdb.com/title/tt3756788/awards/) • [14](https://www.gaga.co.jp/wp-content/uploads/2020/05/history-e.pdf)\n\nCritical response was broadly favorable. The film holds a Metascore of 75 based on 31 reviews, classified as \"generally favorable,\" and a 93% Tomatometer score on Rotten Tomatoes, whose critics consensus describes it as using \"the story of one fractured family to offer universal -- and deeply moving -- observations on the human condition.\"[6](https://www.metacritic.com/movie/our-little-sister/) • [9](https://www.rottentomatoes.com/m/our_little_sister) Peter Bradshaw of *The Guardian* called it quiet, understated, and gentle, presented with \"wonderful freshness and clarity.\"[15](https://www.imdb.com/title/tt3756788/criticreviews/)\n\n## Home media and availability\n\nBlu-ray and DVD editions were released in Japan on December 16, 2015.[16](https://umimachi.gaga.ne.jp/news/) In Japan the film is currently available on subscription services including Netflix, Amazon Prime Video, U-NEXT, and FOD.[10](https://www.justwatch.com/jp/%E6%98%A0%E7%94%BB/hai-jie-diary)\n\n## References\n\n1.
