Mitsuyo Maeda

naturalized as Otávio Maeda (), was a Japanese-born Brazilian ''judōka'' and prizefighter in no holds barred competitions. He was known as Count Combat or ''Conde Koma'' in Spanish and Portuguese, a nickname he picked up in Spain in 1908. Along with Antônio Soshihiro Satake, he pioneered judo in Brazil, the United Kingdom, and other countries.

Maeda was fundamental to the development of Brazilian jiu-jitsu, including through his teaching of Carlos Gracie and others of the Gracie family. He was also a promoter of Japanese emigration to Brazil. His accomplishments led to him being called the "toughest man who ever lived" and being referred to as the father of Brazilian Jiu-jitsu.
