Kanshō Era

Kanshō (1460-1466) was a mid-Muromachi era name, proclaimed on the 21st day of the 12th month of Chōroku 4 (February 1, 1461) in response to the ongoing famine, and used until it was replaced by Bunshō on the 28th day of the 2nd month of Kanshō 7 (1466). The reigning emperor was Go-Hanazono (who abdicated to Go-Tsuchimikado on the 19th day of the 7th month of Kanshō 5), and the shogun was Ashikaga Yoshimasa; the era name derives from a phrase in the Confucian text Kongzi Jiayu. The era's defining event was the Kanshō famine: crop failures continuing from the Chōroku years worsened through Kanshō 2 (1461), reportedly causing tens of thousands of deaths from starvation in Kyoto alone, a crisis in which the monk Gan'ami became known for organizing relief for famine victims. In Kanshō 5 (1464), the shogunal succession question intensified when Ashikaga Yoshimasa's younger brother Yoshimi returned to lay life as heir presumptive, planting the seeds of the factional conflict that would erupt as the Ōnin War in 1467. In sword history, surviving dated works confirm that the Eikyō-Bizen smiths Sukemitsu and Norimitsu of Bizen's Osafune school remained vigorously active throughout the Kanshō years. Sukemitsu's signed katana - "Bishū Osafune Sukemitsu, Kanshō 2, 8th month" (1461) - has a blade length of 61.4cm, a shinogi-zukuri construction with an iori-mune ridge, a temper line mixing gunome and chōji patterns, and a fine itame grain interspersed with mokume. Norimitsu (the second-generation smith posthumously nicknamed "Kanshō Norimitsu" after his later works) left several further dated pieces, including "Bishū Osafune Norimitsu, Kanshō 3, 8th month" (1462) and a katana inscribed "Bizen Province Osafune resident Norimitsu, Kanshō 5, 8th month" (1464), now held in the Nagahama Castle History Museum's digital collection. Sukemitsu was the father of Katsumitsu and Munemitsu, who would become central Sue-Bizen smiths, placing him at a pivotal link between the Eikyō-Bizen and Sue-Bizen generations. Even as famine and a brewing shogunal succession crisis pushed the country toward the Ōnin War, the surviving dated blades of this period show that Bizen's sword production held its quality and pace.
