He was a swordsmith from Yamato and is counted among the “Ten Students of Masamune”.
Later, he moved to Mino.
He is the first generation of the Yamato Kuni school.
After moving to Mino, he became the son of Shizu Saburo Kaneuji, and together with his teacher Kaneuji (of the Kuni school), relocated from Yamato to Mino.
He changed his name from Kunitomo to Kanetomo.
