Yūichi Nakamaru (中丸雄一 Nakamaru Yuuichi, born on September 4, 1983 in Kita-ku, Tokyo, Japan), is a Japanese idol, singer-songwriter, actor, television personality, radio host, and a member of KAT-TUN.
He joined the talent agency Johnny & Associates in 1998 and then officially debuted as part of KAT-TUN in 2006.
Nakamaru was born in Kita-ku, but raised in Sumida-ku, Tokyo. He is the oldest child in a family of five composed of his parents and two younger sisters with 6 and 4 years age difference respectively. He has a fear of heights and phobia of needles.
His reason for applying to Johnny & Associates was that in the last year of junior high school, a female classmate who liked Johnny's idols told him to try out and prepared his application form to the point that he only needed to sign it.
In April 2008, he entered Waseda University and majored in Human Environmental Sciences through the university's undergraduate correspondence course e-school. He successfully graduated in March 2013.
Nakamaru officially joined Johnny & Associates in November 1998 with bandmate Kazuya Kamenashi and agency mates Jin Akanishi, Takahisa Masuda, Taisuke Fujigaya and Ryōichi Tsukada, who were all in the same audition. He was a member of four temporary units while still a Johnny's Jr. - Boys Be Ambitious (B.B.A), Musical Academy Dancing (M.A.D), Best Beat Dancing (B.B.D), and Toshi Otoko.
He joined KAT-TUN when it formed in 2001, and debuted as part of the group in 2006. Besides singing and beatboxing in KAT-TUN, he also writes lyrics for his solo songs or duet songs with the other members. For rap lyrics, he uses the alias Yucci.
