Tomisaburō Wakayama (若山 富三郎, Wakayama Tomisaburō, September 1, 1929 – April 2, 1992), born Masaru Okumura (奥村 勝),[1] was a Japanese actor best known for playing Ogami Ittō, the scowling ronin warrior in the six Lone Wolf and Cub samurai films.

[1] Wakayama tired of this; at the age of 13, he began to study judo, eventually achieving the rank of 4th dan black belt in the art.

[1] In 1952, as part of the Azuma Kabuki troupe, Wakayama toured the United States of America for nine months.

[1] Wakayama taught judo until Toho recruited him as a new martial arts star in their jidaigeki movies,[1] originally using the stage name "Jō Kenzaburō".

[4] His only roles in American movies were as a baseball coach in The Bad News Bears Go to Japan (1978) and as a yakuza boss, Sugai, in Ridley Scott's Black Rain (1989) that delivers a memorable English monologue that becomes a defining moment for the film, and the film's title.
