Kero Kero Bonito (sometimes shortened to KKB) are a British band from London, England. The band consists of vocalist Sarah Midori Perry, producer Gus Lobban, and producer Jamie Bulled. Their name comes from the Japanese onomatopoeic words for frog croaks and a type of fish. The band's music is influenced by J-pop, dancehall, and video game music. They write many of their songs using a Casio SA-45 mini-keyboard. Perry raps in both Japanese and English.
