Yonezawa Castle (Maizuru Castle)

Connection to Swords

Yonezawa Castle's connection to swords cannot be discussed without reference to Uesugi Kenshin, one of the greatest warriors of the Sengoku period. Kenshin was also known as an incarnation of Bishamonten and was revered as a war god, and his mastery of swords was extraordinary. Among all the swords that Kenshin possessed, the most famous is "Himetsuruichimonji." The Ichimonji school was a group of swordsmiths representing Bizen in the Kamakura period, and their style is known for elegant chigirenui blade patterns and heavy jigane. The Himetsuruichimonji is said to have been a family treasure that Kenshin carried from Echigo to Yonezawa like a guardian deity, and it was passed down through the generations as the spiritual symbol of the Uesugi clan. Kenshin also clashed five times with Takeda Shingen at the Kawanakajima battles (1553–1564), and the legendary sword clashes between these two great rivals continue to be recounted as one of the greatest contests in Japanese history. The Yonezawa Domain maintained hereditary clan swordsmiths who created practical yet refined blades befitting the Uesugi family tradition. Naoe Kanetsugu possessed keen aesthetic sensibilities regarding sword art, and even amid the difficulties following Sekigahara, he devoted himself to protecting cultural treasures. The artworks and cultural properties that Kanetsugu collected and protected became the foundation of Yonezawa's cultural heritage and the origin of the enriched collection at the Uesugi Museum. The swords transmitted from the Uesugi clan boast the highest quality and quantity in Tohoku, and particularly the masterpieces from the Koto period collected during the era of Kenshin and Kagekatsu form a magnificent collection comprising the finest examples of the Bizen, Soshu, and Yamato traditions. At the Yonezawa City Uesugi Museum, one can view the treasures of the Uesugi clan up close, including swords designated as Important Cultural Properties, and it has become a sacred destination for Japanese sword enthusiasts. Uesugi Kenshin not only wielded his sword on the battlefield but also possessed an eye for famous blades. The sword aesthetic that he cultivated was inherited by Naoe Kanetsugu and Uesugi Kagekatsu, elevating the cultural standard of Yonezawa's castle town to the highest level in Tohoku. The swords enshrined at Uesugi Shrine are revered today as expressions of Kenshin's martial virtue, attracting martial artists and sword enthusiasts on pilgrimage from across Japan.
