Zeze Castle

Zeze Castle is a historic hirashiro-style Japanese castle situated on a peninsula extending into Lake Biwa in the eastern part of Otsu City, Shiga Prefecture. Commissioned in 1601 by Tokugawa Ieyasu immediately following the Battle of Sekigahara, the fortress was strategically built to control the vital Tokaido highway connecting Kyoto with Edo. The renowned castle architect Todo Takatora designed the layout, which featured a unique four-story keep and a complex arrangement of baileys separated by stone walls and moats that formed distinct islands. Construction was expedited by utilizing materials from the demolished Otsu Castle, and the site subsequently served as the seat of the Zeze Domain under various fudai daimyo clans, most notably the Honda clan who ruled for thirteen generations.

The castle's history is marked by both strategic importance and environmental challenges. Its lakeside location made it susceptible to land erosion, requiring constant maintenance, and it suffered severe damage during a major earthquake in 1662. Following the Meiji Restoration, the main structures were dismantled or sold off in 1870, leaving the site in ruins. Despite the loss of the original buildings, several significant architectural elements have survived. Original gates from the inner bailey were relocated to nearby religious sites, including the Zeze Shrine, Shinozu Shrine, and Muchisaki Hachiman-gu, where they remain preserved today as important cultural heritage assets.

Currently, the former inner bailey has been transformed into Zeze Castle Ruins Park, which is open to the public. While the majestic keep and residential quarters are gone, visitors can still view remaining sections of the original stone walls and a reconstructed gate that hint at the fortress's former grandeur. The park serves as a peaceful historical landmark where the legacy of the Edo period's defensive architecture endures amidst the natural beauty of Lake Biwa. The survival of the scattered gates provides a tangible connection to the past, illustrating the castle's enduring influence on the local region long after its military function ceased.
