The anime is an adaptation of a song that was originally released for FM Miyazaki Joy, a local FM radio station’s driver‑safety campaign commercial. The commercial’s jingle became so popular that listeners requested the commercial itself to air in place of regular songs. NHK later acquired the rights, commissioned a music video, and produced a cleaned‑up version of the track in which a significant portion of the lyrics were changed. This is a rare case, as most Minna no Uta songs are created by public broadcasters like NHK; this one originates from a private broadcaster.
