Masato Hoshi became pretty popular among young women in the mid-1970s. He released a few single records of his TV drama songs and other pop songs. He was even a regular on a variety TV show, "Ginza NOW!" as a singer (1975). His head shot photos sold well.
In the 1980s, he started acting more challenging roles, not depending on his handsome look.
Retired from acting for health reasons in 1987.
