Tokugawa Yorinobu (徳川 頼宣, April 28, 1602 – February 19, 1671) was a Japanese daimyō of the early Edo period. Born under the name Nagatomimaru (長福丸), he was the 10th son of Tokugawa Ieyasu, by his concubine Kageyama-dono. On December 8, 1603, Yorinobu received the fief of Mito, then rated at 200,000 koku, as his fief. Mito had formerly belonged to his older brother, Takeda Nobuyoshi. Following his stipend increase to 250,000 koku in October 1604, he came of age on September 12, 1606, taking the name Yorimasa, and receiving the court rank of junior 4th, lower grade (ju-shi-i-ge) and the title of Hitachi no Suke. On January 6, 1610, he was transferred to a 500,000 koku fief in Suruga and Tōtōmi Provinces (thereby founding Sunpu Domain centered on Sunpu Castle), and took the name Yorinobu. How
