Kubota Castle (久保田城, Kubota-jō) is a Japanese castle in Akita, Akita Prefecture, Japan. Throughout the Edo period, Kubota Castle was home to the Satake clan, daimyō of Kubota Domain, rulers of northern Dewa Province. The castle was also known as "Yadome-jō" (矢留城) or "Kuzune-jō" (葛根城). In the official documents of the Tokugawa shogunate, the castle was called "Akita-jō" (秋田城), although this name is now more commonly used to refer to the Nara period fortified settlement of Akita Castle which was nearby.
