Hisaemon no Jo Fuyuhiro was the son of Soshu Hirotsugu and, on the invitation of the daimyo Fukushima Masanori, moved to Hiroshima from Wakasa in 1606. There were two generations; one characteristic of this first generation is the small size of "saku" in the signature.
Fukushima Masanori (1561-1624) came from a samurai family originally from Owari. He served under Hideyoshi who gave him the castle of Owari as a fief. After Hideyoshi's death and in order to win him over to the Tokugawa rule, Ieyasu gave his adopted daughter in marriage to Masanori's son. Victorious at the battle of Sekigahara in 1600, Masanori was made daimyo of Aki (Hiroshima).
