The highly awaited anime adaptation of Uoto’s manga 100 METERS is gaining momentum with a major update. Ahead of its theatrical debut in Japan on September 19, 2025, the film has officially announced ten new cast members, adding to the growing excitement around the title. Alongside this casting news, details of its international rollout have also been confirmed, solidifying its place as one of the biggest anime releases of the year.
With the first trailer already sparking interest earlier this year, the new announcement comes as another boost for fans eagerly awaiting the emotional and visually striking story to hit the big screen. The film is not just staying within Japan’s borders. Audiences in North America will be able to catch it in theaters this October thanks to distribution by GKIDS, while viewers in the UK and France will also have access through an international release campaign that is being rolled out in phases across several countries.
The film is helmed by director Kenji Iwaisawa and produced by Rock ’n’ Roll Mountain, a studio known for its distinctive style and bold storytelling. The screenplay is penned by Yasuyuki Muto, while Keisuke Kojima is in charge of character design and animation direction. The musical score is composed by Hiroaki Tsutsumi, whose past work has consistently drawn praise for its emotional depth. The creative team behind the film received early acclaim at the prestigious Annecy Animation Festival, setting high expectations for the final product.
The latest addition to the film’s voice cast introduces a fresh layer of emotional and narrative complexity. The newly revealed cast includes Jun Kasama, Rie Takahashi, Yuki Tanaka, Atsumi Tanezaki, Aoi Yūki, Yūma Uchida, Junya Enoki, Haruki Ishiya, Hiiro Ishibashi, and Tomokazu Sugita. These actors will portray characters ranging from youthful versions of key leads to new supporting roles, giving the story more depth and dimension.
Based on Uoto’s deeply introspective and resonant manga, 100 METERS is set to explore themes of time, memory, and redemption. The story is centered around characters whose emotional distances from one another feel harder to cross than the physical space suggested by the title. As the characters struggle to reconcile with past choices and present realities, the narrative unfolds in ways that are as touching as they are thought provoking.
As fans wait for the theatrical release, the latest announcements signal that 100 METERS will not only live up to the high expectations but may surpass them. With a strong production team, a globally inclusive release strategy, and a voice cast filled with fan favorites, the film is positioned to leave a lasting mark both in Japan and internationally.
