Edo was the sword’s age of connoisseurship: the Hon’ami appraisers, the shogunal register of famous blades of 1719, and a thriving literature turned the sword into an object of study even as it ceased to be drawn in war.
This blade was signed by Bitchu no Kami Tachibana Yasuhiro(備中守橘康広). Yasuhiro was active in sword-forging during the Kanbun (1661-1673: Early Edo Period). Yasuhiro belonged to a prestigious sword school called Kishu Ishido and Osaka Ishido School. The back of the tang has an inscription of Kikumon (chrysanthemum emblem). He was allowed to inscribe this emblem, which is the symbol of the Japanese emperor. His sword forging technique was so great that the emperor permitted him to use this emblem, which was honorable for any swordsmith. Ishido School His father, Tosa Shogen Tachibana Yasuhiro(土佐将監橘康廣), 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(Late Muromachi period), Sukenaga and his school moved from Bizen province to Omi 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. Kishu& Osaka Ishido School As of the early Edo period, many Ishido swordsmiths moved to other parts of Japan, looking for better opportunities. 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, Yasuhiro’s father, who belonged to Omi Ishido school, moved from Omi province to Kishu province. It is said that the father was the founder of Kishu Ishido school and played an essential role in making this school prosperous. Yasuhiro was born as the son of the head of Kishu Ishido school. And he mastered excellent sword forging techniques from his father. And it is said that Yasuhiro served Tokugawa Yorinobu, the first head of Kishu domain, who was the 10th son of Tokugawa Ieyasu. Yasuhiro exclusively forged swords for Kishu domain for many years. Later in his career, Yasuhiro received the honorable title “Bitchu no Kami” in 1657 and moved to Settsu city in Osaka to spread the tradition of Ishido school. He built the foundation of Osaka Ishido school. Yasuhiro is known as one of the most prominent figures that made Osaka Isido school prosperous during the early Edo period. Osaka city flourished as a castle town and became the business center during the early Edo period. Many swordsmiths moved to Osaka to look for better opportunities. They not only forged swords for those Samurai who lived in Osaka but also for feudal lords nationwide. Among many swordsmiths active in the same period as Yasuhiro, he was one of the most famous figures in Osaka Ishido school.
