From Aoi Art：Munetsugu Koyama, who resided in Mutsu Province, Shirakawa in Oshu, was an active swordsmith and a student of Koyama Munetsugu.
He was also known by the name Hakuryushi and learned sword-forging techniques well from his master, sometimes even surpassing him in the quality of his works.
However, with the arrival of the Meiji era and the issuance of the Haitōrei (Sword Abolishment Edict), he was forced to give up swordsmithing.
He passed away in 1888 at the age of 53.
