Tatsunosuke Sakonji is a police officer who is more often seen with the other policemen -usually Ryotsu, Sakonji and Honda- off duty (in casual wear) than on duty (in uniform). Superbly muscular and tall in appearance, Sakonji is skilled in the Japanese martial art of Judo, but displays a very unhealthy obsession with a fictional female video game character named Saori.
