As amusing as this Band-Maid video is, it’s even funnier to learn that it is an April Fool’s joke carried out to an extent that only the Japanese can imagine. My Japanese is not up to discerning this myself, but I am reliably informed that the band even went to the trouble of changing the lyrics of the original song to Kansai-ben, which is a Kyoto dialect that is said to descend from the geisha speech of the past.
