Ishino Yoko (born: February 20, 1968) was an idol singer active in the second half of 1980s. She is the younger sister of Ishino Mako, a popular late 1970s idol.
She was born as second daughter of three sisters (Ishino Mako is the oldest sister 7 years older than her, there's a youngest sister who later also became actress). Her parents owned a handbag company. She grew up in a wealthy family in a 10 rooms big two-stories house with big garden ( Japanese style garden + western style garden + a pond, source: wikipedia). In kindergarten, she had a weak body and shy, she only played in the garden with her best friend: a st. bernard dog named "Buzz". To improve her physicality, her parents made her train figure skating, which she won a competition and became her special skill (*which later came in handy when she played a drama about skating).
When she was in her first year of high school, she visited her sister drama filming site and was made to play as extra with the role of a passerby. From there, she got scouted. At first, she had no interest in entertainment and wanted to become a makeup artist instead (after she was impressed watching Ishiko Mako's makeup artist doing their job backstage) but somehow they could persuade her.
In her second year of highschool, to prepare for her debut, she moved to Tokyo and transfered to Horikoshi High School (*a high school with a lot of idols and young celebrities). Among her idol classmates, there were other Yokos such as Nagayama Yoko and Minamino Yoko (Nanno). And one year her junior, there was Oginome Yoko.
Ishino Yoko made her singing debut on April 25, 1985, which made her one of the infamous "group 1985" idols (debuted the same year as Saito Yuki, Nanno, Asaka Yui, Nakayama Miho, Onyanko Club, etc).
In her career, she has released a total of 7 singles and 1 original album. Two of her singles reached #41 and #54 in Oricon chart (with those two songs combined accumulated 37,000 sales) while the others didn't make it to top 100. There's no information about her total song sales.

Teddy boys look like this, probably a delinquent subculture.
