[ Highlight ] First generation Satsuma Masafusa "正房" was the second son of Maruta Bingo Ujifusa "丸田備後守氏房", a swordsmith from Mino. The first signature is cut as Ujifusa "氏房". His name was Maruta Hyouemon "丸田兵右衛門", and he learned the Soshu method of forging "延べ物造り" from Takeya Genshichiro En'an "竹屋源七郎延安" in Kyoto. He changed his name to Masafusa and lived in Kagoshima, where he made his sword around the Kan'ei "寛永" period. The vigorous style of the nie-based work had a great influence on the Satsuma swordsmiths of the Shinto sword period. He deceased on 4 October in the second year of the Keian "慶安"(1649). It was inscribed "Satsuma Fujiwara Masafusa", "Izu no Kami Fujiwara Masafusa", "Izu no Kami Fujiwara Masafusa residing in Kagoshima, Satsuma Province", "Satsuma resident Izu no Kami Masafusa", etc. (e.g. "薩州藤原正房", "伊豆守藤原正房", "薩摩国鹿児島住伊豆守藤原正房", "薩州住伊豆守正房"). There are chronological works such as Kan'ei 4 and 12 and Shoho 2 and 3. This sword appears to have been quite long in length, and even after it had been refinished, it still has a dignified appearance.
