Sonny Chiba
Japanese actor and martial artist (1939–2021)

Shinichi Chiba (Japanese: 千葉 真一, Hepburn: Chiba Shin'ichi; born Sadaho Maeda; 22 January 1939 – 19 August 2021) IPA: [tɕiꜜba ɕiɰ̃itɕi], known internationally as Sonny Chiba, was a Japanese actor and martial artist. Chiba was one of the first actors to achieve stardom through his skills in martial arts, initially in Japan and later to an international audience.
Born in Fukuoka, Chiba played a variety of sports in high school, including baseball and volleyball. He also practiced gymnastics and participated at the National Sports Festival of Japan in his third year. When he was a university student, he learned martial arts, earning a black belt in Kyokushin Karate in 1965 and later receiving a fourth degree in 1984.
Chiba's career began in the 1960s, when he starred in two tokusatsu superhero shows. In his first role, he replaced Susumu Wajima as the main character Kōtarō Ran/Seven Color Mask in Seven Color Mask (Nana-iro Kamen) in the second half of the series. However, his breakthrough role was in the 1974 film The Street Fighter. Before retiring, Chiba had also appeared in a number of English language American films, including Kill Bill: Volume 1 (2003) and The Fast and the Furious: Tokyo Drift (2006).
Chiba died of COVID-19 complications at the hospital in Tokyo on 19 August 2021, at the age of 82.

Why this record matters
The phrase “japanese actor and martial artist (1939–2021)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q351732. VIAF identifies the subject as 19398217. The Library of Congress control number is no2004100759. 5 of 5 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1939, 2021, 1965 and 1984.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
