Yasuyoshi was the son of Samonji of Chikuzen province. He migrated to Choshu (Nagato province) sometime prior to 1362, the earliest date inscribed on extant swords bearing Choshu as his place of residence. His recorded signatures include Choshu ju Yasuyoshi as on the sword here, Choshu Yasuyoshi, and the name he is believed to have used early in his career, Yasuyuki. He was succeeded by at least two generations, but this sword is the work of the first-generation Yasuyoshi.
