Nakamaru was born in Kita-ku,. 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. His special skill is in beatboxing and this talent has been recognized by various other celebrities such as Rag Fair's Okkun and Masi Oka. 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 wrote lyrics for his solo songs or duet songs with the other members. For rap lyrics, he uses the alias Yucci.

Nakamaru reported that he went under agent and management mixed contract since January 2024 for his activities with the agency on his newly opened YouTube channel "Nakamaru Ginga Channel". Nakamaru reappeared in a live event, when he took the stage as MC at the opening ceremony of the "Osaka Comic Convention 2025" held in Intex Osaka on May 2, 2025, following his self-impossed hiatus after news of his secret rendezvous with a 20-year old woman in a Tokyo hotel in August 2024, and the dissolution of KAT-TUN in March. He also participated as an exhibitor, with his manga "Yamada-kun no zawameku jikan".

Yuichi Nakamaru became an official manga artist with his first manga, titled Yamada-kun no Zawameku Jikan. It was serialized in Kodansha's Monthly Afternoon magazine from June 23 to November 25, 2023.

JUMP's Ryosuke Yamada, and Sexy Zone's Fuma Kikuchi. He opened a channel for himself, called "Nakamaru Ginga Channeru" (中丸銀河ちゃんねる), with the first video posted on 13 January 2024. The channel's content covers all kinds of activities, from solo talk, to interviews with friends, to gameplays, to travel reports, and work related activities, such as posts about his manga. The official opening is set for the 20th.

Nakamaru announced his marriage to former NTV announcer Rina Sasazaki on 16 January 2024 through the agency's official site. Nakamaru and Sasazaki met in 2015, when she started working at NTV and became a co-worker at Shuichi. Sasazaki eliminated all posts from her SNS on the 16. On August 7, 2024, Shūkan Bunshun reported that Nakamaru had secretly met with a 20-year-old college student at a hotel. Nakamaru responded with an apology "to all concerned", through his agency, which also posted a comment regarding his "lack of awareness and responsibility". As a consequence, of his own volition, he would refrain from all activities for an undisclosed period of time, that included his regular appearances in NTV's Shuichi, TV Asahi's Kaji yarō, and Asahi Osaka's Asa da!
