Kazuma excelled immediately in wrestling. When he was in the eighth grade, Kazuma placed top 8 in All Japan Junior High School Wrestling Champioinships.

This is when Kazuma officially began his career as an "elite wrestler."

By the time he was a senior in high school, Kazuma won all of natinoal tiles such as All Japan High School Wrestling Championships, JOC Cup Junior title, and All Japan High School Greco-Roman Championships.

Kazuma did not stop there.

Kazuma joined Japan's Self-Defense Force after school and continued to compete in wrestling.

From 2012 to 2014, Kazuma won three-consecutive All Japan Wrestling Greco-Roman Championships. In 2013 Kazuma place seventh in World Wrestling Championships as well.

Although Kazuma defeated 2016 Olympic silver medal winner Shinobu Ota in the tournament final to win 2014 All Japan Wrestling Championships, a loss in 2015 All Japan Wrestling Championships prevented him from making 2016 Olympic team.

In 2018, Kazuma made his pro MMA debut and won seven straight fights until he faced Ryo Okada in Shooto Interim Bantamweight title fight.

In 2020, Kazuma signed with the RIZIN Fighting Federation and defeated Taiyo Nakahara in RIZIN 26.
