Eri Nitta

Together with many of the original members of Onyanko Club, Nitta released the single, Shōmikigen (ショーミキゲン ) in 2002. On December 5 that same year, the newly reunited members performed the title song as well as Don't Make Me Take Off My Sailor Suit during the 2002 FNS Kayōsai event on Fuji TV. Takashi Okamura, one half of the comedy duo Ninety-nine, is a huge fan of Nitta, and she performed in the "Uta no Onēsan" (歌のお姉さん ) section of his Tobukusuri variety show. Several years later, during the "Fuji TV 24-hour Police" parody segment of the Mecha-Mecha Iketeru! variety show, Nitta's husband was "shamefully arrested" as the "Onyanko Thief" (due to his having married Nitta). In a segment for the same show in 1999, Nitta fan and tarento Thane Camus and owarai duo Asarido visited Nitta's home.

In 1994, Nitta released a photo book and essay in which she returned to show business. On August 8, 1996 (just before Fuji TV moved to their present location in Odaiba), a reunion event was held for the Yūyake Nyan Nyan TV series. Nitta later married the Fuji TV employee who was in charge of the event.

She made her solo debut on January 1, 1986 with the hit single Winter Opera Glasses, which reached number one on the Oricon charts and sold over 300,000 copies. This was the record for a debut single for a female solo artist until Oricon changed their rules regarding what was considered a "debut" for people who had previously been a member of a group; Yuki Uchida now holds the record for a debut single for a female solo artist. Nitta was given the title "The Million Dollar Smile" on her single covers, and her smile was referred to as the "Nitta Trump", due to the extraordinary price she commanded due to her popularity. She began to regularly release singles and albums from that point.

Nitta made her first appearance as the fourth member of Onyanko Club in April 1985 with an appearance on the group's Fuji TV variety show Yūyake Nyan Nyan. While she initially wanted to quit show business soon after starting, she suddenly became the most senior member of the group on April 25, 1985 following the Shūkan Bunshun Smoking Scandal in which five members (including the first three members) of Onyanko Club were fired.

Just before her solo debut, her father suddenly died of pneumonia on December 24, 1985 after collapsing with a high fever on the set of a movie in Hawaii. During the year following the breakup of Onyanko Club in 1987, as her popularity began to wane, Nitta adopted the pen name of Eri (絵梨 ) (using kanji different from those used in her real name) and began writing lyrics for her own songs. In March 1990, she retired from the entertainment world after telling people she wanted to become a lyricist. She wrote the lyrics for the songs on her last single.

Nitta has since worked as an actress, author, and essayist, as well as participating in the Tokyo community radio program Ginza Radiocity. She has also participated, along with fellow idols such as Toshikazu Fukawa and Chiemi Hori, in programming discussing the 1980s idol star movement. In 2007, she participated in the ōendan for the inauguration of the Kama Burning Heroes, a baseball club started by Rakyō Ide, an owarai performer and member of the talent group Takeshi Gundan.
