The film will open in Japan on April 29.
Snow Man member Ren Meguro stars as Tarō Sakamoto, and Fumiya Takahashi plays Shin Asakura. Meguro read the original manga several years ago, and said that he took on many previous roles to convey something to the audience, but this time he is appearing in Sakamoto Days for his own sake.
Fumiya Takahashi plays Shin Asakura. Aya Ueto plays Tarō Sakamoto’s wife Aoi Sakamoto, while Miyu Yoshimoto plays Tarō Sakamoto’s daughter Hana Sakamoto. Other cast members include Mayū Yokota as Lu Shaotang, Junki Tozuka as Heisuke Mashimo, Akihisa Shiono as Kashima, and Keisuke Watanabe as Natsuki Seiba. Takumi Kitamura, Yūsei Yagi, and Meru Nukumi play Order assassins Nagumo, Shishiba, and Osaragi, respectively.
Yūichi Fukuda (live-action Gintama, Under Ninja) is directing and writing the script for the film. Keiya Tabuchi (Evangelion: 3.0+1.0: Thrice Upon A Time, live-action Attack on Titan, Kamen Rider Amazons) is directing the action. CREDEUS is producing the film with Avex Pictures.
Suzuki published a one-shot titled “Sakamoto” in Jump Giga in December 2019, and then launched the main manga in Shueisha‘s Weekly Shonen Jump magazine in November 2020. The manga began its “final battle” in August 2025.
Viz Media and MANGA Plus are publishing the manga in English digitally. Viz is also publishing the manga in print. MANGA Plus describes the story:
