Matsumoto Castle
When Toyotomi Hideyoshi transferred Ieyasu to the Kantō region in 1590, he placed Ieyasu’s former retainer Ishikawa Norimasa in charge of Matsumoto Domain, with assessed "kokudaka" of 100,000 "koku". Norimasa and his son Yasunaga built much of the present-day Matsumoto Castle by 1593–94. The Ishikawa were confirmed as "daimyō" of Matsumoto Domain after the formation of the Tokugawa shogunate, but were dispossessed due to a political scandal in 1613 involving Ōkubo Nagamasa.
