History Early life and education Kitayama was a sports-oriented youth who devoted himself to football until his junior high school years. He entered Horikoshi High School, which is well known for its entertainment course, through a soccer-based recommendation. At the time, Kitayama was unaware that the school had an entertainment course or that many entertainers attended it; however, he later recalled realizing the presence of celebrity classmates when students with flamboyantly dyed hair entered the hall during the entrance ceremony. Influenced by his classmate Tomohisa Yamashita, who was already active in the entertainment industry, Kitayama auditioned for Johnny & Associates and joined the agency in 2002, during his second year of high school and subsequently entered the entertainment industry.

Career at Johnny & Associates (Kis-My-Ft2) After being selected for several Johnny’s Jr. groups, he was chosen as a member of Kis-My-Ft. in 2004. Following lineup changes, the group was reorganized as Kis-My-Ft2 in 2005. As Kis-My-Ft2, they worked as backup dancers for KAT-TUN and other artists before making their CD debut as a group with the single “Everybody Go” in August 2011. He graduated from Asia University in 2008.

Within Kis-My-Ft2, Kitayama made use of his vocal skills and often sang key parts of the group’s songs alongside Taisuke Fujigaya.

Departure from Johnny & Associates On August 31, 2023, he left Kis-My-Ft2 in order to pursue an individual career and also departed from Johnny & Associates.
