In his younger days, Akisame left the leaf village and traveled the world to further the development of his unique Jyuken style, taking in aspects and inspiration from other styles he studied. He later met and became friends with Teno and Rodukaime. During one of his journeys he met an old man who lived in the mountains and was a great master at both crafting and wielding weapons. Because the man was terribly sick he requested Akisame to take his life away in a duel so that he could die a warrior's death. Akisame initially refused, but eventually had to throw him off a cliff after a forced confrontation. Before dying the man left his final 3 swords to Akisame. During more travels Akisame ultimately left Konohagakure and joined Kumogakure to begin a new life in the land of lightning.
