He is credited with the invention of judo techniques like sankaku-jime and hiza-juji-gatame, which were subsequently incorporated into other disciplines, including sambo, Brazilian jiu jitsu and mixed martial arts.

[2][3] He was especially active in the kosen judo environment of Okayama, Nagoya and Tohoku, standing out as the third greatest figure of this competition only behind Hajime Isogai and Tsunetane Oda.

A turmoil took place when the Okayama team put to use a new submission hold taught to them by Kanemitsu, the hiza-juji-gatame (膝十字固め), which the Kanazawa side protested to be too similar to ashi garami, a technique banned in 1916.

Victory was accomplished in a large part by the introduction of yet another new technique, the sankaku-jime (三角絞), which has been speculated to have been innovated by Yaichihyōe and his student Masaru Hayakawa, Noboru's younger brother, as well as other apprentices like Katsusaburo Ichinomiya and Tokubei Takahashi.

He submitted 5th dan Kazuo Yamauchi by okuri eri jime, pinned Sumitake Shinmen with yoko-shiho-gatame, and went to fight the feared Tokyo judoka Shojiro Hashimoto, who was thought to be as proficient on his feet as Kanemitsu was on the ground.
