Kappa no Qui Quo Qua, カッパのクィクォクァ

Music video for the song Kappa no Kui Kuo Kua by Japanese vocal group Duke Aces and actress Nobue Ichitani that was featured on NHKs Minna no Uta program. The video was animated by Yoji Kuri.The video aired in 1975, but was considered lost media some time later. It was recovered thanks to the Minna no Uta Hakkutsu Project.

The Minna no Uta Hakkutsu Project started in 2009 and is an initiate to archive ~500 lost songs from the program due to loss of master tapes, audio, and film from 1961-1982. Due to the copyright law of the time, price of film reels, and overwriting tapes. Similar issues plagued the BBC (e.g. Doctor Who missing episodes). By 2016, 220 songs were recovered with 100 of them being music videos.
