Miho Nakayama（中山美穂）was born in 1970 in Nagano Prefecture but was raised in Koganei City, a suburb of Tokyo. In her first year of junior high school, she was discovered in Harajuku by a modeling agency and worked in commercials and magazines, before her debut as an actress in a drama as a high school punk. As that same drama's theme song, she released her first single, "C"in June 1985. It peaked at No. 12 on Oricon and became the 67th-ranking single of the year. I tried looking at the lyrics but couldn't really understand what the "C" stood for. A couple of months later, her debut album of the same name would be released.
BTW, this is my 100th post!
