Little is known of Harunobu's early life; his birthplace and birthdate are unknown, but it is believed he grew up in Kyoto. It is said he was forty-six at his death in 1770. Unlike most ukiyo-e artists, Harunobu used his real name rather than an artist name. He was from a samurai family, and had an ancestor who was a retainer of Tokugawa Ieyasu in Mikawa Province; this Suzuki accompanied Ieyasu to Edo when the latter had his capital built there. Harunobu's grandfather Shigemitsu and father Shigekazu were stripped of their hatamoto status when they were found to be involved in financing of gambling and other activities; they were exiled from Edo and relocated to Kyoto. At some point, Harunobu became a student of the ukiyo-e master Nishikawa Sukenobu.
