English translation

Wink were a very popular idol duo in late 1980s to mid 1990s, consisted of Suzuki Sachiko (born: February 22, 1969) and Aida Shoko (born: February 23, 1970). 

Suzuki Sachiko and Aida Shoko first met in 1987 when they both participated in a beauty contest held by a magazine. They befriended each other for awhile but stop catching up. One year later, in 1988, a coincidence (they called it fateful meeting) brought them together when Sachiko and Shoko somehow went to audition at the same company in the same day. They were about to audition as solo singer, but the audition staff thought their voices would be better to complement each other and suggested them to form a duo. A series of coincidences brought them together, Wink were born. Even their birthdates almost looks like a coincidence

* I can't find the source but remember to read it somewhere, but the group names proposed were: "Kira Kira Kagayaki" (means: dazzlingly bright, or something like that.), "Oz" , and "Twinkle Winkle". They took the middle of "Twinkle Winkle" and it became Wink. Sounds much better and suit their images best!  ૮ ˶ᵔ ᵕ ᵔ˶ ა.

Wink came with a unique concept: singing with expressionless faces without smiling. Add that with their doll-like costume (in earlier phase of their career; changed into normal clothings in later years) and doll-like coreography. Imagine opening a music box, then two extremely beautiful dolls come out singing and dancing, that's Wink! Their concept were different, fresh and made them stand out.

Wink have their place among elite top idols in their era. In their peak (late 1988 until 1992), their songs started from "Ai Ga Tomaranai" until "Real na Yume no Jouken" were ranked like this in Oricon chart: 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 5, 4, 7, 10. In total, Wink have 5 songs that reached #1 in Oricon chart. They have performed 1 time in Kohaku Uta Gassen (a legendary new year eve TV program that has been aired every single year since 1953; an all-star song battle where only elite singers of the year will be invited to perform there). 

In the survey of "Top 50 Idols of All Time" by a music program in 2011 based on their record sales, Wink were placed in rank #26 with a total of 7,490,000 sales.

Starting from 1993, Wink started to decline. Their song "Sakihokore Itoshisayo" reached #9 in Oricon chart (the last time they reached top 10 in Oricon chart) and generated high sales, providing them a last lifeline. But after that, they declined permanently. In 1996, their agency told them to stop their activity as Wink. Sachiko and Shoko needed to part way and going solo on their separated ways. 

Wink have been "defunct" starting from 1996. They don't want to call it "disbanded", and they are not totally disbanded, since Sachiko and Shoko would performed as Wink again (for one night only) at least once every decade; mostly every 10th of their anniversary. So far they have made reunions in 1998, 1999, 2008, and 2018.
