The founder of Takada lineage in Ken'mu (1330's) in Bungo domain was TOMOYUKI 友行 who was a disciple of SAMONJI 左文字 in Chikuzen domain. During the Sengoku Warning States period, The sword makers of Takada 高田 school had worked for a feudal lord
Ōtomo Sōrin exclusively. It's workmanship covers wide range such as Soushu, Bizen, Mino or Yamashiro and Yamato traditions.
The subject maker MASAYUKI 正行, reportedly a son of SANEYUKI 実行, is distinguished as a work of the 1st generation who appeared in Keian era (1648-) then had traced his descent in 3 generations during Edo period under the patronage of Hosokawa 細川 clan.

The entire blade is massively heavy on both hands holding brave shape for a Samurai of warlike spirit. Using fine steel with an elaborate forging process generates fine skin of Ko- Itame hada and precise darkish lines of Chikei forms typical Masame hada ware. Careful work of Nakago tang and it's filemarks and typical example of inscription that preserves an good taste of patina in 370 years.
