The Peanuts (ザ・ピーナッツ Za Pīnattsu?) is a Japanese vocal group consisting of twin sisters Emi Itō (伊藤エミ, Itō Emi) and Yumi Itō (伊藤ユミ, Itō Yumi).[1] They were born in Tokoname, Aichi, (Japan) on April 1, 1941;[citation needed] soon after their birth, the family moved to Nagoya.
In the first years they sang Japanese covers of standards, foreign hits, and Japanese folk songs, then they began singing originals, written by their producer, Hiroshi Miyagawa, and such songwriters as Koichi Sugiyama and Rei Nakanishi. Later they embarked on a brief acting career, notably in the 1961 film Mothra. The pair retired from performance in 1975.[citation needed]
They are remembered most for their versions of European songs and for a handful of Japanese pop songs, such as "Furimukanaide" ("Don't Turn Around&quot . Their performing style played heavily on their being nearly identical twins with voices only slightly apart in pitch (making a duet sound like a solo artist using reverb).
