Matsumoto was born in Toshima, Tokyo, as the youngest child in his family. He has an older sister whose support of KinKi Kids influenced his decision to join Johnny & Associates in 1996. Thinking it might bode good luck, he sent his application to the agency on his elementary school graduation day and received a phone call weeks later from president Johnny Kitagawa himself, inviting him to attend a rehearsal instead of being auditioned. Due to this, Matsumoto is frequently referred to as one of the elite within the agency.3 Matsumoto graduated from Horikoshi Gakuen, a renowned high school known for its many performing arts alumnae such as Kyoko Fukada and Ai Kato, in March 2002 at the age of 18.45
