Antique Japanese Sword Wakizashi Signed by Nobuyoshi with NBTHK Kicho and Tokubetsu Kicho Tosogu Certificate 【Description】 Summary This blade was signed by Minamoto Nobuyoshi (源信吉). According to its NBTHK authentication paper, it was made by a late-gen Nubuyoshi. The first-gen Nobuyoshi is also known as Shinano Kami Minamoto Nobuyoshi (信濃守信吉), who was active during the early Edo period (1644-1673) in Yamashiro province (Today’s Kyoto prefecture). The first-gen Shinano Kami Nobuyoshi was allowed to inscribe a chrysanthemum emblem, which is the symbol of the Japanese emperor. His sword-forging technique was so great that the emperor licensed him to use this emblem, which was quite honorable for any swordsmiths. Echizen no Kami Rai Minamoto Nobuyoshi was also allowed to inscribe a chrysanthemum emblem. There are two late-gen Nobuyoshi. One of them is the second-gen Shinano Kami Nobuyoshi and Echizen no Kami Nobuyoshi. Both of them are the children of the first-gen. Mishina School The generations of Nobuyoshi belonged to Kyoto Mishina school. Mishina school was created by the first-gen Mutsu no Kami Omichi (陸奥守大道), also known as Kanemichi. It is said that initially, Kanemichi was from Mino province, exclusively forging blades for Shingen Takeda, a famous feudal lord. Later on, he moved to Kyoto by bringing his four sons and founded his school in Kyoto. Four sons were Iga no Kami Kinmichi(伊賀守金道)、Izumi no Kami Rai Kinmichi(和泉守来金道), Tanba no Kami Yoshimichi(丹波守吉道) and Echu no kami Masatoshi(越中守正俊). His sons and the first-gen Nobuyoshi were known as Kyoto Gokaji(京都五鍛冶), prestigious swordsmiths forging in Kyoto in the early Edo period. Mishina school was prosperous throughout the Edo period and spread to other parts of Japan, such as Osaka. The superb craftsmanship of the Mishina school was passed down for generations. *Please keep in mind that there are a couple of Kitae Kizu on this blade.
