began work on the initial storyboards for "Princess Mononoke" in August 1994, based on preliminary thoughts and sketches from the late 1970s. While experiencing writer's block during production, accepted a request for the creation of "On Your Mark", a music video for the song of the same name by Chage and Aska. In the production of the video, experimented with computer animation to supplement traditional animation, a technique he would soon revisit for "Princess" . "On Your Mark" premiered as a short before "Whisper of the Heart". Despite the video's popularity, said that it was not given "100 percent" focus.
