Hiyoshi was originally born Kazuko Koike（小池和子）from Saitama Prefecture just above Tokyo in 1947. She debuted in 1967 under the stage name of Kazuko Ike（池和子）but after her first three singles failed to succeed, there was a career reset with a change in name to Mimi Hiyoshi in 1969. Her 2nd single after the name change (her 5th single overall) was the one that finally got her into the stratosphere. "Otoko to Onna no Ohanashi" was released in May 1970 as this melancholy ballad with Hiyoshi singing from the point of view of the fellow trying to advise a lady on the facts of love (and love lost) after she's just been dumped. After listening to it once, I had thought the fellow was a particularly caring bartender but looking at the lyrics by Kyosuke Kuni（久仁京介）, I think Hiyoshi could be playing a regular barfly with the heart of a wannabe Casanova.
Supposedly Hiyoshi was known for her coquettish voice, but I think for this song and even "Osaka Koi Uta" which I heard on the stereo, her vocals were much more commanding (although still high-pitched) in the "I've-been-there-I-know-what-it's-like" tone. Masakazu Mizushima（水島正和）was responsible for the melody whose guitar and strings added that layer of further softness to the singer's advice to the lovelorn.
"Otoko to Onna no Ohanashi" touched a chord with listeners. It reached its peak at No. 6 on Oricon and sold over 600,000 records. And she made her sole appearance on the Kohaku Utagassen on the power of this song. Hiyoshi released 48 singles and 13 albums up to 2010.
