This blade was signed by Gassan Sadayoshi (月山貞吉) in Feb, the 4th year of the Ka-Ei era(1851). Gassan Sadayoshi’s real name is Gassan Yahachiro. He was born in Dewakoku(Yamagata prefecture today) in 1781. Gassan is the name of the school he belonged to. It was initially founded during the Heian period(late 12th century). It is said that the school name “Gassan” (月山) came from the fact that they forged swords near the mountain called Gassan in Dewakoku. In Sadayoshi’s early career, he learned sword forging technique from his father, Okuyama Yasaburo Sadachika(山弥三郎貞近), who is said to have been a descendant of a member of O-Shu Gassan school (奥州月山), one of the oldest Gassan schools. When Sadayoshi became about 20 years old, he went to Edo city(today’s Tokyo) to serve Suishinshi Masahide(水心子正秀) as an apprentice. Sushinshi Masahide is known as one of the most skilled and famous swordsmiths at the end of the Edo period(150-200 years ago). After ten years of apprenticeship under Masahide, Sadayoshi mastered excellent craftsmanship. And he moved to Osaka in 1833 when he was 30 years old. He founded Osaka Gassan school there, improving his sword-forging technique even more and eventually settled there. He also trained many apprentices, who later became notable swordsmiths at the end of the Edo period. While Gassan school was known as one of the most prestigious schools from the Kamakura period(late 12th century), its presence faded in the early-mid Edo period. However, after Sadayoshi became a highly-regarded swordsmith at the end of the Edo period, the whole school revitalized and flourished again because of his continuous effort. Sadayoshi adopted a son from Tsukamoto family and named him Sadakazu, who later became one of the most famous swordsmiths in the post Samurai period(Meiji era). Father and son spent many years researching traditional Gassan style swords and finally made Ayasugihada, the signature design of Gassan school. Ayasguhihada looks undulating grain pattern in the Jihada(steel surface), which resembles a Japanese cedar grain. Gassan Sadayoshi also forged other styles of swords aside from Ayasugi Hada Jihada. Gassan Sadayoshi died at the age of 71 in the third year of the Meiji era(1870). His son, Sadakazu, preserved the tradition of Gassan, and he passed it down to Sadakatsu. The Gassan school has been running for the 6th generation. The current Gassan alive is Gassan Kazutoshi, and his son is Gassan Sadanobu. They still keep forging traditional Japanese swords in Nara prefecture today. It is appraised as a Hozon Token (保存刀剣) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai: 日本美術刀剣保存協会).
