Hideyori was the second son of Shiba Yoshiyori. He served Oda Nobunaga at the Battle of Okehazama (1560) and in the siege of the Ishiyama Hongan-Ji. After the fall of the Takeda in 1582 he was established at Takatô castle in Shinano province. When the former Takeda retainers rebelled after Nobunaga’s death, Hideyori fled to Owari province. He entered the service of Toyotomi Hideyoshi and participated in the Komaki Campaign (1584), the invasion of Kyushu (1587), and the siege of Odawara (1590). He was afterwards awarded Iida in Shinano province.
