佐和山城
Sawayama Castle is a historic castle in Kansai dating from the Origins predate the Nanbokucho period; extensively rebuilt by Ishida Mitsunari after 1590, whose lord was Ishida Mitsunari / Tokugawa clan (demolished).
Overview
Sawayama Castle was built on Mount Sawayama, a 232-meter-high mountain in the northwestern part of Hikone City, Shiga Prefecture. As a strategic stronghold of Omi Province, it played an important role from the Medieval period through the Sengoku period. The castle's history is said to trace back before the Kamakura period, and during the chaos of the Northern and Southern Courts era, it became a contested objective between both sides.
The figure who inscribed this castle in history was Ishida Mitsunari, known as the foremost of the Five Administrators of the Toyotomi government. Following the Odawara Campaign of Tenshō 18 (1590), Mitsunari was granted 194,000 koku of Omi Province by Toyotomi Hideyoshi and established Sawayama Castle as his primary residence, undertaking a major reconstruction of the castle. Leveraging his talents as an administrator and economist, Mitsunari improved both the castle and its castle town, and Sawayama developed into a major stronghold for the Toyotomi government's control of the eastern provinces.
As commemorated in the verse "Two things exceeded Mitsunari — Shima Sakon and Sawayama Castle," the castle held special significance as Mitsunari's seat of power even in those times. The castle was developed into a fully-fledged early-modern fortified complex with a five-story tenshu, but it was abandoned following Mitsunari's defeat at the Battle of Sekigahara (1600). After Mitsunari's death, the house of Ii Naomasa, acting on Tokugawa Ieyasu's command, eventually constructed Hikone Castle in close proximity to Sawayama Castle, and the stones from Sawayama Castle are said to have been repurposed in its construction.
Today, only the remains of the honmaru, ninomaru, sanomaru, and other kuruwa earthworks survive, with all structures having been lost. The site has been preserved as a historic monument of Shiga Prefecture and attracts numerous visitors as a pilgrimage destination for admirers of Ishida Mitsunari. From the summit, one can simultaneously view Lake Biwa and Hikone Castle, allowing visitors to experience the strategic importance of that bygone era.
Connection to Swords
Sawayama Castle's connection to swords involves Ishida Mitsunari's paradoxical role: the very official who administered Toyotomi Hideyoshi's 1588 sword hunt (katanagari) — which confiscated weapons from farmers and crystallized the samurai–commoner division — was also a commander who led 80,000 troops at Sekigahara. As a senior Toyotomi administrator, Mitsunari had access to distinguished blades collected from across Japan. His family's refined sword collection, accumulated through Toyotomi service, was seized and scattered after Sekigahara. Today visitors to Sawayama's earthwork ruins often seek connections to Mitsunari's material culture, and Hikone — built partly from Sawayama's stone — holds related artifacts.
