Producer Rina Sobue stated that in an interview with The Television that a live-action television drama adaptation of 10 Things I Want to Do Before I Turn 40 had been heavily requested, and the manga's publisher Libre had given the rights to TV Tokyo, having been impressed with their late-night television dramas.[1] Several office scenes depicted in the show were created for the drama adaptation, and episode 8 featured original screenplay.[1]
The series stars Shunsuke Kazama as Suzume and Kōhei Shōji as Keishi.[4] Sobue stated that Kazama was the top choice for Suzume though internal staff discussions, due to his age and because the director, Ikeda, had previously worked with him in the live-action television drama adaptation of the manga Hatsukoi, Zarari .[1] The staff chose Shōji for the role of Keishi, describing his audition as "relaxed, yet sincere."[1]
Additional cast members include Amon Hirai as Kaede Tanaka, Riko Takayama as Akane Utagawa, and Keisuke Watanabe as Shō Yoshizawa.[16] Sobue stated that their roles had expanded from the original manga, and that Takayama had also been cast at the insistence of Ikeda, who had also worked with her in Hatsukoi, Zarari.[1] Yūki Hirako from the comedy duo Alco & Peace was cast as Keisuke Kuroki, an original character created for the drama adaptation.[16] Sobue had created the character while imagining Hirako working at an advertising agency and had personally asked him to play the role.[1] Voice actress Kotono Mitsuishi provides the voice of Suzuko.[14] Sobue asked Mitsuishi to play the role, likening her to her roles as Misato Katsuragi from Neon Genesis Evangelion and Usagi Tsukino from Sailor Moon, and that she had cast Mitsuishi as Suzuko because Suzuko "watched over" Suzume just as Misato had watched over Shinji Ikari and how Sailor Moon had "been by [her] side since childhood."[1]
