Yonezawa Castle

Yonezawa Castle is a historic flatland-style Japanese castle situated in the center of Yonezawa city within Yamagata Prefecture, Japan. The site's origins trace back to 1238 during the Kamakura period, initially serving as the seat of the Nagai clan before passing to the powerful Date and Gamō families. Its most significant era began in 1591 when it came under the control of the Uesugi clan. Following the Battle of Sekigahara, Uesugi Kagekatsu extensively renovated the fortress between 1608 and 1613. Due to political suspicion from the Tokugawa shogunate and reduced land revenues, the reconstruction featured modest defensive works without stone facing and a limited three-story donjon, reflecting the clan's diminished but enduring status throughout the Edo period.

The castle holds deep historical importance as the birthplace of the famed warlord Date Masamune and the final administrative center for the Uesugi daimyō until the Meiji Restoration. It also serves as the resting place for Uesugi Kenshin, whose grave was relocated within the castle walls by his successors. In 1873, shortly after the abolition of the han system, all remaining castle structures were demolished. Today, the site has been repurposed into a public park and houses the Yonezawa City Hall in the second bailey. The main bailey now features Uesugi Shrine, established in 1872 and later moved to the original donjon location, which honors the ancestors of the Uesugi clan and remains open to the public as a cultural landmark.
