Keigo Higashino’s The Keeper of the Camphor Tree—known as Kusunoki no Bannin in Japan—is getting an anime film adaptation. A-1 Pictures (Sword Art Online, Solo Leveling) handles production for the feature, which is set for sometime in 2026 with Tomohiko Ito (Sword Art Online) directing.
Aniplex will handle distribution for the film.
The Kusunoki no Bannin novel first hit shelves in Japan in 2020. Publisher Abacus has an English release planned for November 2025 under the title The Keeper of the Camphor Tree, describing the story like so:

The Keeper of the Camphor Tree starts with Reito Naoi, a man in his early 20s, being unjustly fired from his job. Enraged and fuelled by feelings of revenge, he tries to steal a valuable device from his workplace, but things don’t go to plan, and he ends up arrested.
In jail, Reito is paid an unexpected visit by a lawyer who offers to arrange for his release, if he complies with the wishes of the lawyer’s client. Seeing no alternative, Reito accepts and soon discovers that the lawyer’s client is his aunt. When Reito tells her that he has no plans for the future, she gives him an order: ‘What I want you to do is to guard a camphor tree.’ And thus begins Reito’s custodianship of a camphor tree standing on the grounds of a shine – a camphor tree with a mysterious legend associated with it…
