Yuichi Nakamaru

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[3] 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.[4]

His special skill is in beatboxing and this talent has been recognized by various other celebrities such as Rag Fair's Okkun[5] and Masi Oka.[6]

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.[7][8]

Nakamaru officially joined Johnny & Associates in November 1998[9] 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.

In 2009, he appeared in his first ever leading role in a drama in TBS TV's "Rescue ~Tokubetsu Kōdo Kyūjotai".[10]
