<human>: Jin Akanishi (Chi Xi  Ren , Akanishi Jin, born July 4, 1984) is a Japanese musician, singer, songwriter and actor. He has been active since 1998, first as one of the two lead vocalists of the popular J-pop boy-band KAT-TUN. Since the group's official debut in 2006, they have achieved 14 consecutive number ones (including studio albums) on the Oricon charts. In 2009, Akanishi started his solo career, and since then has released two studio albums (Japonicana, #JustJin), and two mini albums (Test Drive, Mi Amor).

After he was made a Johnny's Jr. member in 2000, Akanishi was part of a number of groups like Musical Academy Dancing, J2000 and B.A.D., before being drafted into a six-member unit in 2001 with other juniors Kazuya Kamenashi, Junnosuke Taguchi, Koki Tanaka, Tatsuya Ueda and Yuichi Nakamaru. Though the group was originally meant to only be backup dancers for Koichi Domoto of KinKi Kids, the sextet's unexpected popularity led their agency to allow them to expand into a separate group called KAT-TUN, an acronym formed by the first letter of the members' surnames. Despite the group's popularity (they even released DVDs of their live concerts in 2003 and 2005--a first for Johnny's groups that hadn't debuted), they were not allowed to make their bow until five years later in 2006, to immense success.  Much to the Japanese public's surprise, Akanishi announced in a press conference on October 13, 2006, that he was leaving the country to study English abroad for an indefinite amount of time. Despite his absence, KAT-TUN were obliged to continue its activities Akanishi finally returned from Los Angeles in the United States after six months on April 19, 2007. He quickly resumed work by joining his bandmates on their nationwide tour on April 21.  Akanishi was also a songwriter for the group, having written songs for KAT-TUN and for himself, including "Hesitate", "Love or Like" (from Cartoon KAT-TUN II You), "Lovejuice" (B-side of the limited edition 2 of "Don't U Ever Stop"), "Care" (from Break the Records: By You & For You), and "Wonder". The song "Wonder" is a collaboration with R&B artist, Crystal Kay in 2009, and Akanishi also featured in her song "Helpless Night". He can play the guitar and has composed both music and lyrics for "Murasaki (murasaki)", "ha-ha" and "Pinky". He also collaborated with bandmate Ueda to create the song, "Butterfly" (from Best of KAT-TUN).  At the event of Tokyo Girls Collection on September 5, 2009, Jin appeared as a special guest to promote his new movie, Bandage, and he performed the movie's theme song which marked this as the solo debut under the temporary band unit, LANDS, with Takeshi Kobayashi, the producer of Mr. Children. Kobayashi wrote the lyrics and music of their debut single "Bandage". It was released on November 25, and debuted at number one on the Oricon charts. In 2010, on January 13, was released the studio album Olympos, which also topped the Oricon charts. On January 19, the band held their only live concert, titled LANDS Last Live.
