石田正宗

Ishida Mitsunari is often depicted as a man of ledgers and logistics rather than a warrior, yet his ownership of a Masamune blade reveals a deeper dimension. In the feudal hierarchy of the Momoyama period, possession of a Masamune sword was a declaration of status that transcended mere connoisseurship; it signified that a lord possessed both the means and the cultural authority to hold what was considered the finest class of blade in Japan. After the catastrophic defeat of the Western Army at Sekigahara on 15 September 1600, Mitsunari's possessions including this blade passed to the Tokugawa victors. The sword thus became a witness to the moment that ended the Toyotomi era and inaugurated 260 years of Tokugawa rule. Now in the Tokyo National Museum, Ishida Sadamune is prized both for its metallurgical excellence and for the drama that clings to its name: a blade made by the greatest smith, owned by a man who gambled everything on a single battle, and lost.
