In 1954, Joe Shishido signed on as a contract player at
Nikkatsu. Studio bosses encouraged Shishido to change his name, as popular tales of the
samurai Miyamoto Musashi contained a villain named
Shishido, and they were trying to model him into a romantic lead. Shishido refused. His first major role was in ''Policeman's Diary
(1955, Keisatsu Nikki), in which he played a young patrolman who challenges a police chief in a kendo'' (bamboo sword fighting) match. His altered look has been described both as "ruggedly handsome", and as chipmunk-like.{{cite web|last=Atkinson |first=Michael Though he worked predominantly in comic action roles, Shishido also gained a tough-guy loner image in such films as
Seijun Suzuki's
Youth of the Beast, (1963) in which he played an ex-cop who infiltrates two rival yakuza gangs. Shishido is best known in the West for films he made with Suzuki, e.g.
Detective Bureau 2-3: Go to Hell, Bastards! (1963) and
Gate of Flesh (1964). His best known film internationally is Suzuki's
Branded to Kill (1967), in which he starred as the number three hitman in Japan. The film received only moderate success on its original release, due largely to poor promotion by Nikkatsu stemming from the studio's growing disaffection with Suzuki, which ended with the director's firing. Shishido later recalled seeing the film with friends and finding the theater nearly deserted. Nikkatsu action movies began to lose favour through the late 1960s and production was scaled back resulting in fewer jobs for Shishido. He began taking roles with other companies and in television, which were primarily of a comic nature. He also starred in Nikkatsu "new action" films such as the
all-star vehicle ''
Yakuza Bird of Passage: Bad Guys' Work (1969), with Akira Kobayashi and Tetsuya Watari, and Bloody Battle (1971). In 1971, Shishido ended his contract and left the failing company, which had transitioned into softcore roman porno'' ("romantic pornography") films in order to stay profitable. ==Free agent==
