Isshuukan

In 1963, the Japanese music group Bonny Jacks released the song "Isshuukan," which was selected to be featured on the popular NHK television program Minna no Uta. This program regularly showcased short animated music videos alongside songs, and a special animated clip was produced to accompany the track. The video was designed to visually interpret the lyrics and mood of the song, offering viewers a simple yet engaging audiovisual experience during the broadcast.

The music video for "Isshuukan" was created as a standalone piece, intended to air within the program's rotation. However, over time, the original footage became lost, with no known copies surviving in broadcast archives or private collections. This has led to its status as lost media, leaving only the audio of the song and memories of the broadcast as remnants of the original work. The video remains a curious footnote in early Japanese animation history, representing a brief collaboration between music and television animation during the era.
