Mizuno clan
Following the creation of the Tokugawa shogunate, Okazaki Domain was created, and Ieyasu’s close retainer Honda Yasushige was assigned possession of the castle. The Honda were replaced by the Mizuno clan from 1645-1762, and the Matsudaira (Matsui) clan from 1762-1769. In 1769, a branch of the Honda clan returned to Okazaki, and governed until the Meiji Restoration.
