Features:\u3000Hizen Kuni Ju Mutsu no Kami Tadayoshi (3rd generation), also known as Shinzaemon, was the legitimate son of the 2nd generation Tadayoshi (Tadahiro).
\nHe received the title of Mutsu Daijo in October of Manji 3 (1660), and later became Mutsu no Kami in Kanbun 1 (1661).
\nHe passed away on January 2nd of Jokyo 3 (1686).
\nThis sword is published in the Hizen To Taikan on page 296.
\nUnusually, this blade is not in the typical suguha style, but instead features an elegant gunome-midare, with deep nioikuchi and a boshi that turns back deeply and roundly.
\nAlthough this sword holds the Tokubetsu Hozon certificate, its quality is undoubtedly Saijyo Saku.
\nIt is listed in the Hizen To Taikan.<\/p>\n

Aoi Art\u2019s Comment:\u3000This koshirae appears to have belonged to a daimyo.
\nBoth the blade and the koshirae suggest it was owned by a person of high status.
\nMost signed Hizen blades are short in length.
\nIt is extremely rare to find a long blade signed by the 3rd generation Tadayoshi.
\nPublished in Hizen To Taikan, p.296.
\nA rare and magnificent katana with equally impressive fittings.<\/p>\n
