The Space Brothers manga is concluding with its final volume on July 22, 2026, alongside a special chapter drawn in space aboard the ISS. The anime series and prequel film aired in a free marathon on ABEMA in July 2026.
The Space Brothers manga is ending its 18-and-a-half-year run with the release of the 46th and final volume on July 22, 2026. Kodansha is publishing a special edition that includes a booklet and a recap map. The same day, a previously untold chapter titled 425.5 will be released digitally, drawn remotely in microgravity via a robotic arm inside the International Space Station's Kibo module. This project, called Mission: SPACE COMIC, uses JAXA's commercial Kibo utilization program for the first time to produce a comic in space, replicating the hand movements of creator Chuya Koyama.
In the week leading up to the manga's conclusion, ABEMA aired all 99 television episodes of the Space Brothers anime and the prequel film Space Brothers #0 in a free marathon from July 17 to 21, 2026. The broadcast ran over five days with two daily blocks, and free streaming was available for one week after. The prequel film covers a story not included in the original manga or anime.
The culmination of the manga and the real-world space mission tie directly into the series' theme of space exploration. The robotic arm operation is the first commercial use of JAXA's new robotic arm. The chapter 425.5 will be released on the same date as the final volume, marking the end of the series with a story literally drawn from space.
