The manga "The Long Summer of August 31" (Japanese: "8月31日のロングサマー") by Ikkado Ito is getting a double adaptation in Japan: As publisher Kodansha announced on August 31, 2026, the series will receive both a TV anime adaptation and a live-action series. The animation will be handled by studio SHAFT, known for series such as "Puella Magi Madoka Magica" and "Monogatari." Along with the announcement, a first teaser visual was released.
The fact that the news came on August 31 is no coincidence: The plot revolves around a day that endlessly repeats for the two high school students Suzuki and Takagi. Only the two of them retain their memories with each loop and try together to find out the reason for the time loop. A possible cause is an unfinished task that Suzuki has been putting off during summer vacation as his "biggest goal as a boy." The publisher describes the work as a youthful time-loop comedy that directly tackles love.
The manga has been serialized in Kodansha's Morning magazine since March 2023; so far, 13 compiled volumes are available, with the latest released in August 2026. Author Ikkado Ito previously gained recognition with the manga "I'm Not Meat: Get Your Filthy Paws Off Me!" (Japanese: "Boku wa Oniku ja Nai"). For the two announced adaptations, neither director, cast, nor broadcast dates have been set yet; SHAFT is the only officially named production partner for the anime version. Further details are to be announced via the work's official X profile (@831longsummmmer).
Alongside the announcement, the publisher is providing a special chapter on its reader platform Comic Days that can only be read on August 31 – a now annual tradition for the work. Additionally, the first four volumes are available there for free for one week to get readers in the mood for the adaptations.
