This journey will become the next melody—The “Sound! Euphonium” series has depicted the high school students’ youth dedicated to wind ensemble music for 10 years. “Sound! Euphonium 3,” which concluded with a moving finale during its 2024 TV broadcast, will finally arrive in theaters in 2026 as the concluding “Final Movement.”
“Final Movement” is directed by Tatsuya Ishihara, who has led the Kyoto Animation production team for the past 10 years, with Taichi Ogawa—who has been a central pillar of the series alongside him—serving as co-director.
In addition to Kyoto Animation’s refinement of the original footage, Jukki Hanada has written a new script, and numerous new scenes have been added. Including performance scenes not depicted in the TV series, the entire staff is working together to deliver a theatrical film worthy of the title “Final Movement.”
Here lies the vow made that day—
The anime “Sound! Euphonium” heads toward its grand finale.“Sound! Euphonium: Final Movement” Part 2
Opens Friday, September 11, 2026!
