  • Native name: 瀬戸康史
  • Also Known as: せと こうじ, Setomaru
  • Nationality: Japanese
  • Gender: Male
  • Born: May 18, 1988
  • Age: 35
Seto Koji is a Japanese actor and singer. He's a member of the acting troupe D-BOYS.
His childhood dream of becoming a vet changed suddenly with the end of his Junior High School time when he watched the TV series Orange Days. The praised drama and performance by Tsumabuki Satoshi inspired his wish to become an actor. After discussing his plans with his parents, they decided to support their son and enrolled him to a local acting school. After one year in training, he was cast in 2005 as Kanno Makoto, the snobbish main antagonist in the comedy TV Series Rocket Boys. His official D-BOYS logo is a chameleon, in reference to his versatility.

He officially announced his marriage with Yamamoto Mizuki in 2020. On May 16, 2023 they announced the birth of their first child.
