勝新太郎
Several films feature Okada Izō as protagonist, most notably Hideo Gosha's "Hitokiri" (1969) (portrayed by Shintaro Katsu) and Takashi Miike's "Izo" (2004) (portrayed by Kazuya Nakayama). The NHK Taiga drama "Ryōmaden" (2009) featured him several times (portrayed by Takeru Sato) as one of Sakamoto Ryōma's friends and Takechi Hanpeita's assassins.
