In Japan, they are remembered for a run of pop-chart hits from roughly 1976 to 1979, but in the United States, they are best known for their short-lived 1980 NBC TV variety show Pink Lady and Jeff, later released on DVD under the same title.

[5] Mitsuyo Nemoto and Keiko Masuda were childhood friends who grew up and attended school together in Japan's Shizuoka Prefecture.

In May 1974, the duo formed a folk group called "Cookie" (クッキー, Kukkī) and passed Yamaha's "Challenge on Stage" (チャレンジ・オン・ステージ, Charenji on Sutēji) audition.

[7] Nemoto and Masuda first appeared in March 1976 on NTV's prime-time TV talent show Star Tanjō!, performing a cover of Pīman's 1974 song "Heya wo Dete Kudasai" (部屋を出て下さい, "Please Leave the Room").

They were also affiliated with the talent management firm T&C Music (T&C ミュージック, Tī ando Shī Myūjikku), which gave them a makeover to compete with the teen trio Candies.

Songwriter/producer Shunichi Tokura named the duo "Pink Lady" after the cocktail, while Yū Aku was assigned to write lyrics for their songs.

In addition, Nemoto and Masuda took the stage names of "Mie" (ミー, Mī, sometimes spelled "Mii") and "Kei" (ケイ), respectively.

[14] The peak of Pink Lady's popularity was in 1978, during which they headlined a concert at Korakuen Stadium in Tokyo with over 100,000 fans in attendance.

Because many of these shows aired on the same day, Mie and Kei had to commute from one network to another, with both of them having an average daily sleep time of 45 minutes.

[20] The duo's hectic schedule created the term "Busy as Pink Lady" (ピンク・レディー並みの忙しさ, Pinku Redī Nami no Isogashi-sa) in Japan's entertainment world.

As for the rest of the profits, it was reported that T&C Music was a subsidiary of a secret firm run by a yakuza syndicate, which collected 70% of the earnings.

Mie and Kei turned down an invitation to perform on NHK's long-running annual New Year's Eve television music program Kōhaku Uta Gassen (Red and White Song Battle) to host their own TV special Pink Lady: 150 Minutes of Sweat and Tears on New Year's Eve!!

In May 1979, Pink Lady performed a charity concert at the Osaka Expo '70 Stadium in front of 200,000 spectators, of which all profits went to UNICEF.

[25] Mie and Kei appeared as guest stars on a Leif Garrett TV special that spring,[15] performing what was to be their first American single, a disco tune called "Kiss in the Dark," recorded phonetically in English and released by Curb Records,[15][24][22] followed by an entire English-language album (a collection of disco tunes and ballads, including a cover of The Left Banke's 1966 classic "Walk Away Renée").

[1][27] The fact that Mie and Kei knew very little English limited their potential as comedians, and also caused them a great amount of stress, since both were essentially forced to memorize dialogue neither could understand.

The albums and singles they released in America are now out of print, and one of the only ways for U.S. fans to get hold of Pink Lady's music is through Japanese imports.

Pink Lady's lack of visibility at home while they were filming their variety show in Hollywood, as well as the decline of disco music, hurt their record sales even in Japan.

Tokura sued T&C Music for unpaid royalties totaling to US$17,700 after the management firm lost millions of dollars on investing in Pink Lady and Jeff.

[5] Four years and seven months after their formation, Pink Lady performed their final concert at Korakuen Stadium on March 31, 1981, before going their separate ways.

[22]　A PlayStation 2 version of this game was also released on October 31, 2002, by Sunsoft, titled Hissatsu Pachinko Station V5 Pink Lady (必殺パチンコステーションV5 ピンクレディー).

In 2005, the duo announced their farewell tour in Japan, titled Pink Lady Memorial Concert Vol.

In October 2007, Pink Lady sued Kobunsha for ¥3.7 million after the publisher's magazine Josei Jishin used photos of the duo in an article on dieting through dancing without their permission.

and announce their comeback by releasing a specialized photo-book titled Heibon Premium: We Are Pink Lady (平凡Premium We are ピンク・レディー).

[43] In 2009, the Yū Aku tribute album Bad Friends was released, featuring covers of Pink Lady's songs by Anna Tsuchiya & Mari Natsuki, Watarirouka Hashiritai 7, Checkicco, Yu Takahashi & Nana Yanagisawa, and many more.

[5] In 2014, Tokura introduced the 14-member tribute group Pink Babies (ピンク・ベイビーズ, Pinku Beibīzu) as part of his "Pan-Pacific Project".
