Features:　Gassan Sadakazu is a representative swordsmith of the Meiji and Taisho periods and is also known as Sadakatsu’s father. He was active since the end of the Edo period and continued to make swords even though many swordsmiths gave up making swords after the sword prohibition ordinance was enacted, demonstrating his excellent skills. In 1906, he was appointed as an “Imperial Artist,” the highest rank for swordsmiths at that time, and worked on swords for the Emperor Meiji and other members of the imperial family and influential military figures.
