Rip Slyme (often stylized as RIP SLYME) is a Japanese hip hop group. It is composed of four MCs; Ryo-Z, Ilmari, Pes & Su, and a DJ, Fumiya. Their sound derives its influences from old school hip hop and other hip hop such as The Pharcyde, De La Soul, Public Enemy, Jurassic 5, the Beastie Boys, DJ Premier and Leaders of the New School.
All members of Rip Slyme are Japanese.
The statement states that the group is Japanese, not each individual member. The nationality of each member is not stated. The system found it difficult because it has assumed that Japanese group means they are all Japanese.
