Sword of Echizen Yasujiro

Echizen Yasujiro (First Generation) was an officially recognized swordsmith of the Edo shogunate, summoned to serve Yūki Hideyasu, daimyo of the Echizen domain, and relocated to Echizen (present-day Fukui Prefecture). He was granted permission by Tokugawa Ieyasu and Tokugawa Hidetada to carve the three-leaf hollyhock crest on the nakago. His works, produced from the Keichō era (1596–1615) through the Genna era (1615–1624), are particularly renowned for their high quality among Shintō-period swords and were especially prized as presentation pieces to the Tokugawa shogunal family and various daimyo. Yasujiro's blades are renowned for their excellent jigane and the consistently refined quality of their hamon. His gunome and konie-deki hamon patterns, while influenced by the Sōshū tradition, display the distinctive elegance unique to the Echizen school. The nakago bear signatures such as "Echizen-jū Yasujiro" or "O-bushū Edo Echizen-jū Yasujiro," and when combined with the hollyhock crest, they visually demonstrate his deep connection to the shogunate. Although the name "Yasujiro" was passed down through successive generations after the First Generation's death, his original works are particularly highly regarded by connoisseurs, with multiple blades designated as Important Cultural Properties and held in major art museums and museums throughout the country, including the Tokugawa Art Museum. As a representative Shintō swordsmith of the early Edo period, Echizen Yasujiro opened new creative ground while absorbing the three traditions of Bizen, Yamashiro, and Sōshū. His blades are positioned in Japanese sword history as embodying the "ideal model of an official shogunal swordsmith."
