The castle was built in 1604 by Satake Yoshinobu, a daimyo relocated from Hitachi Province by the Tokugawa shogunate.
The castle lacks a central donjon, a design choice intended to avoid suspicion or conflict with the shogunate's strict castle-building regulations.
Its defensive system primarily utilized steep earthen embankments and deep moats rather than the conventional stone masonry seen in other major Japanese castles.
The onsite Satake Historical Museum holds a specialized collection of documents and armor related to the Satake clan's 260-year governance of the region.
Senshu Park, which encompasses the ruins, was designed in the 19th century and incorporates elements of traditional Japanese landscape gardening.
Kubota Castle Ruins, located within Senshu Park in Akita City, serve as the historical site of the former residence of the Satake clan. The site features a reconstructed Sumiyagura turret and the Satake Historical Museum, which houses artifacts from the Edo period. Unlike many Japanese castles, Kubota Castle was constructed without a traditional stone wall foundation, relying instead on natural terrain and earthen ramparts. The grounds contain a significant collection of cherry trees, making it a prominent destination during the spring blossom season. Several historical structures, including the castle gate, have been meticulously restored to reflect their original architectural style. The site covers a hilltop elevation that provides panoramic views of the surrounding Akita urban landscape. It functions as a public park with walking paths integrated into the former bailey layouts.
