Antique Japanese Sword Katana Signed by Tameyasu with Tokubetsu Hozon Certificate 【Description】 This blade was forged by Mutsu no kami Tachibana Tameyasu(陸奥守橘為康) during the Kanbun-Enpo era(1661-1681:Early Edo period). Tameyasu was the maker’s name used by the second-gen Kishu Ishido Yasuhiro at the end of his career. His father was Tosa Shogen Tachibana Yasuhiro(土佐将監橘康廣), and his younger brother is Bitchu no kami Yasuhiro, both of whom are famous swordsmiths.His real name is Tomita Goro Zaemon(富田五郎左衛門). Tameyasu belonged to a prestigious sword school called Kishu Ishido and Osaka Ishido School. His father was born in Omi province, located in Shiga prefecture. And he belonged to Omi Ishido school during the early Edo period. Ishido school was initially founded by Sukenaga, an offspring of Ichimonji Sukemune, who made Fukuoka Ichimonji school in Bizen province(Today’s Okayama prefecture). During 1492-1501(Mid Muromachi period), Sukenaga and his school moved to Omi province from Bizen province after being summoned by Gamou family, a powerful feudal line in that region. Sukenaga started to live in front of Ishido temple, and he changed his surname to Ishido. As of the early Edo period, many Ishido swordsmiths moved to other parts of Japan. There are four areas: Edo, Osaka, Kishu(Wakayama prefecture), and Chikuzen(Fukuoka prefecture). Omi Ishido school is the origin of whole other Ishido branches that flourished during the Edo period. Following this trend, his father moved to Kishu province from Omi province. It is said that the father was the founder of Kishu Ishido school. Tameyasu and his father forged swords near Wakayama castle in Kishu province first. And, they moved to Settsu city in Osaka. They also built the foundation of Osaka Sekido school.Tameyasu is known as one of the most prominent figures that made Osaka Isido school prosperous during the early Edo period.
