Taira no Kiyomori was a powerful twelfth-century Japanese military leader whose name still appears in history lessons, drama and popular culture, which helps explain why it works so well as a joke reference. Online, short Japanese rap clips like this one circulate as shareable soundboard audio, detached from any single video and reused whenever a creator wants a bold, rhythmic punch. Its appeal is less about the original performance than about recognition, timing and the surprise of hearing a historical figure named in a modern rap style.
