A single perfect song stretched into animation that doesn't need to prove anything. Watanabe finds the entire world in a child's secret, turning a moment of quiet wonder into something you didn't know you were missing. The kind of thing that reminds you why music videos matter at all.

Chii-chan no Himitsu is a single-episode music video made for the song of the same name, performed by Ritsuko Oowada. The song was featured on NHK's Minna no Uta program. Michinari Watanabe handled the animation for the video.
