Musukko Club

Musukko Club (息っ子クラブ) was a short-lived male spin-off idol group of Onyanko Club. They made their debut in 1986 with the song Boku-tachi no Season, and broke up after their February 15, 1987 concert at Nippon Budokan. The seven members of the group were Ken Iwashiro, Shūsuke Namiki, Yoshinori Satō, Yōji Sawamukai, Kō Shimizu, Hirotoshi Shinozaki and Hiromitsu Shizuku. After 3 decades, the group reunited in 2016 and has been active ever since.
