Live-action film[edit]
Main article: One Week Friends (film)
A live-action film was released in February 2017. The film is directed by Shōsuke Murakami and written by Yōko Izumisawa.[17]
Carl Kimlinger of Anime News Network gave One Week Friends an overall B+ rating. He wrote that the premise can push its dramatic moments a little too far and almost nothing happens throughout the first half of the series. Regardless, Kimlinger praised the plot's character development, saying that it saves the first half with its progression through little events; he added that the dramatic scenes are nicely underplayed to help viewers care for the characters. Kimlinger wrote that Brain's Base and director Tarou Iwasaki provide the series with a style that's perfect, calling the minimalist backgrounds evocative with the right mood and the character animations superb, saying "that makes the show what it is: a sleeper delight, plain and simple."[18]
The manga has had over 1 million copies printed in Japan.[19]
