Hayakuchi Kotoba

A music video for the song "Hayakuchi Kotoba" by the vocal group Dark Ducks, created for the long-running NHK program Minna no Uta. The short features the group performing the rapid-fire tongue-twister song, accompanied by simple, animated visuals that match the playful and challenging nature of the lyrics. The video was broadcast as part of the program's regular rotation of musical segments.

The song itself is a tongue-twister, a series of increasingly difficult phrases meant to be recited quickly, and the animation likely illustrated the words in a whimsical style. However, the video is now considered lost media. No known copies survive in any archive or private collection, and its original broadcast remains the only confirmed instance of its existence. The exact content of the animation and its full duration are unknown, making it a notable piece of lost anime history.
