He was at first a student of Yoshizumi Kosaburo 1st (1699-1753) and identified himself as Yoshizumi Ichijuro.  From 1747 he appeared at the Morita-za, one of the three venues of Edo.  Afterwards he became a disciple of Fujita Yoshiji 1st (1714-1771）, and changed his own stagename to Fujita Okada.  In 1768 he took the name Koide, and in opposition to Fujita Yoshiji's monopoly on the Ichimura-za, became active at the Nakamura-za, together with Nakamura Fujiro 1st (1719–86), receiving recognition also in Osaka.  During the Meiwa-Tenmei period (1764–89) when the "meriyasu" genre of solo songs was in vogue he received recognition for "shirotae" (白妙, "white cloth cherry") and the "kouta" song "kurokami" ("black hair").

Ukiyo: Ukiyo (浮世 , "Floating World") describes the urban lifestyle, especially the pleasure-seeking aspects, of the Edo-period Japan (1600–1867).
