Jun Matsumoto is a Japanese idol, singer, actor and radio host. He is a member of Japanese boy band Arashi and is best known to Japanese television drama audiences for his portrayal as Tsukasa Dōmyōji in the Hana Yori Dango series, in which he won GQ Japan's Man Of The Year Award under the singer/actor category for his work in the drama.
He was born in Toshima, Tokyo, 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.
