Hiroki Matsumoto (松本 大輝, Matsumoto Hiroki, born March 29, 1999) is a Japanese actor from Sapporo, Hokkaido. He stands 182 cm tall and has blood type O. He is represented by Stardust Promotion. His path to acting began unexpectedly: while studying to become a sports trainer, he was awarded the Grand Prize at the prestigious 31st Junon Superboy Contest in 2018. This recognition marked the start of his artistic career. He made his acting debut in 2019 with a role in the drama Rinshō Hanzaigakusha Himura Hideo no Suiri, and has since steadily built a presence in television and film. His breakthrough came in 2022, when he was cast as the lead in the series Ultraman Decker, playing Kanata Asumi—a role that connected him directly to the iconic tokusatsu franchise. Beyond his screen work, Matsumoto has shown strong athletic ability, particularly in basketball, a sport in which he competed at the national level during his school years. His hobbies include watching films and collecting sneakers. *** Not to be confused with the voice actor of the same name, also written 松本大輝, affiliated with 81 Produce.
