Tsuyoshi Yoshida (1924 – January 5, 1988), known by the pen name Go Mishima (三島剛, Mishima Go), was a Japanese homoerotic fetish artist and founder of the magazine . He is noted for his illustrations of "macho-type" men, often with yakuza-inspired irezumi tattoos. Mishima, along with Tatsuji Okawa, Sanshi Funayama, and Go Hirano, is regarded by artist and historian Gengoroh Tagame as a central figure in the first wave of contemporary gay artists in Japan.
