Ryujin Minamoto Sadakazu's real name is Adachi Kazuki, and he lives in Ryujin Village, Tanabe City, Wakayama Prefecture. Ryujin Village is home to the Nyunokawa River, a tributary of the Hidaka River, and his workshop is located in Tonohara. Because of the magnificent natural environment, the name Ryujin, and the proximity of the sacred mountain Mt. Koya, Sadakazu's swords look somewhat mysterious. His master was Ryujin Taro Minamoto Sadayuki, a master swordsman who was designated as an intangible cultural asset and died in 1996 at the age of 88. This sword is a gem that will surely satisfy you in both iai and appreciation. The silver habaki is engraved with the Sanskrit characters of Fudo Myo-o. The sword is in excellent condition with no flawt.
