Zeebra (ジブラ, Jibura, born April 2, 1971), real name Hideyuki Yokoi (横井英之), is a Japanese hip hop recording artist and DJ who made his first appearance in 1995. Zeebra is a former member of the hip-hop group King Giddra, which also included DJ Oasis and K Dub Shine, and the older brother of fellow hip hop recording artist SPHERE of INFLUENCE. He went on to pursue a solo career shortly after in 1997, and signed with the Future Shock record label. Zeebra is one of the most popular rappers in Japan, and his popularity is not specific to either gender. He appears not only in hip-hop magazines, but also in fashion and street culture magazines. He often features in and produces other rappers' songs, and appears in their videos. He has also performed live with various rappers from America. In 1998 Zeebra undertook his first solo tour. He became recognized as an individual rapper for the first time, making hip-hop more familiar to Japanese listeners. In the same year he started the first hip-hop TV program in Japan, titled Beats to the Rhyme. One of Zeebra's songs was used in a Nike promotion video for NBA Japan games. The following year Zeebra released the single "Mr. Dynamite", the first hip-hop single to break into the top 50 on the Japanese pop charts. In June 2000, he released his new album Based on a True Story, which sold 250,000 copies. At the end of that year Zeebra started his first Japan tour, the first hip-hop event to sell out. In 2001 Zeebra released the single "Never Enuff", the theme song for a Japanese movie called Brother, directed by Takeshi Kitano and starring Claude Maki. In 2002 he temporarily rejoined King Giddra, but has been doing solo work since 2003 and has released many songs. At present, he is producing songs not only for rap artists, but also for pop stars like Namie Amuro.
