Music video for the song Oto no Symphony by the NHK Tokyo Children's Choir (NHK Tokyo Jidou Gasshoudan) that was featured on NHK's Minna no Uta program. The video was animated by Shuuichi Nakahara.

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.
