Finger 5 (フィンガー5, Fingā Faibu) was a Japanese pop group, initially composed of the four Okinawan Tamamoto brothers Kazuo, Mitsuo, Masao, Akira, and sister Taeko.
The group, who were partly inspired by the Partridge Family TV show, struggled in the Tokyo area, often playing at venues that catered to US military, as they had done in Okinawa.
Later that year they debuted on the Philips label, with First Album, and scored a huge hit with the single “Kojin Jugyo (Private Lessons)" in 1973.
“Kojin Jugyo” sold almost a million and a half copies, and follow-up singles "Koi no Dial 6700 (Love Call 6700)" and “Gakuen Tengoku” were also major hits.
The group was feeling overwhelmed by the sudden stardom thrust on them, and after a goodbye tour, relocated to the United States for late 1975 and early 1976.
