Itakura Shigenori

Itakura Shigenori (板倉 重矩) was a Japanese daimyo of the early Edo period. Shigenori's daimyō family claimed descent from the Shibukawa branch of the Seiwa-Genji. The Itakura identified its clan origins in Mikawa province, and the progeny of Katsuhige (1542–1624), including the descendants of his second son Shigemasa (1588–1638), were known as the elder branch of the clan. Katsuhige was Shingeori's grandfather; and Shigenori was the eldest son of Shigemasa.

Shigenori's youth was spent in Mikawa province. In 1615, Shigenori's father was granted yearly revenues from Mikawa in honor of his warrior conduct during the Siege of Osaka.
