On Your Mark

Ghibli Experimental Theater On Your Mark (ジブリ実験劇場 On Your Mark, Jiburi Jikkengekijō On Yua Māku) is an animated music video created by Studio Ghibli for the song "On Your Mark" by the Japanese rock duo Chage & Aska. The song was released in 1994 as part of the single "Heart". In 1995, Hayao Miyazaki wrote and directed the short film for the song as a side-project after having writer's block with Princess Mononoke. The anime music video is non-linear, providing multiple reiterations and alternate scenes to depict the events. The music video added sound effects to the audio track, but contains no dialogue. Miyazaki purposely misinterpreted the lyrics to present his vision of a world where the surface becomes inhospitable and humans live in an underground city. He made the video cryptic to evoke creative interpretations among viewers.

The music video follows two policemen who raid a religious cult and find an angelic being only to have her taken away and confined to a laboratory. Haunted by the fate of the "angel", the two men formulate a plan and break into the laboratory. Fleeing in an armored truck the three plummet into an abyss after trying to force past a police aircraft along a narrow suspended roadway. After a montage of the previous scenes, the armored truck suddenly rockets into an apartment complex, allowing their escape. The three escape to the surface, ignoring the radiation and danger signs, emerging near an encased nuclear reactor. The two men set the "angel" free and she flies off into the sky.

The music video was well-received and praised for its animation and attention to detail. It premiered as a short before Studio Ghibli's Whisper of the Heart and has since been released on Laserdisc and DVD as part of All Things Ghibli Special Short Short.

The video begins with shots of a vacant village, overgrown with weeds, and the concrete sarcophagus of a covered-over nuclear reactor in the background. As the music begins, the scene changes to a sci-fi-style nighttime military-style police raid on a cult. Futuristic flying troop transports crash through the windows of a tower topped by gigantic neon-lit eyes and occupied by armed defenders. The policemen exchange gunfire and grenades with cultists whose hoods depict an enormous eye. The victorious police begin to sort through the bodies of the cultists, two policemen find what appears to be a girl, lying unconscious, with large feathered wings on her back.
