Which music unit performed the Yo-kai Watch anime opening theme "Gera Gera Po Song"?

King Cream Soda performed the Yo-kai Watch anime opening theme “Gera Gera Po Song.”

The song was created specifically as the opening theme for the anime adaptation of Level-5’s Yo-kai Watch franchise. King Cream Soda was formed around the project, bringing together rap, female and male vocals in a deliberately energetic style suited to the series’ playful supernatural world. The track became the group’s debut CD single in Japan in April 2014.

Its music blends pop, rock, hip-hop, Japanese folk styles, and enka-like passages. The repeated “gera gera po” phrase and simple dance helped make it especially popular with children. The song reached No. 4 on the Oricon Singles Chart and No. 9 on the Billboard Japan Hot 100.

Listeners sometimes choose Dream5 because that group also performed prominent Yo-kai Watch music, especially “Yo-kai Exercise No. 1.” HardBirds recorded a later cover associated with Yo-kai Watch 4, but the original anime opening was King Cream Soda’s signature song.
