Formerly in the possession of the Date family of daimyo [feudal lords] in Sendai; presented by the shogun Tokugawa Hidetada to Date Tadamune in the twelfth month of 1617 on the occasion of the latter's marriage to the shogun's adopted daughter. Hidetada's Buddhist name was Daitokuin and as a consequence this blade too is sometimes known as Daitokuin; see Murakami Kosuke, Showa token meibutsu cho [An album of celebrated swords appraised during the Showa period] (Tokyo, Yuzankaku, 1979), p. 188
