Standing 168 cm tall with a 168 cm reach and fighting from an orthodox stance, she trains out of Fighter’s Flow in Tokyo.

Over the course of her professional career, she has competed in major promotions including DEEP Jewels, Rizin, Bellator MMA, and the Professional Fighters League.

Her career record reflects 13 wins against 4 losses across 18 professional bouts, with victories coming by decision, knockout, and submission. She continues to be recognized as one of Japan’s most experienced female Flyweight competitors on the international stage.
Early Life and Background
Kana Watanabe was born on August 21, 1988, in Tokyo, Japan. She grew up in the Japanese capital and currently resides there. Watanabe began her martial arts journey at the age of seven when she started training in judo at Rinkai Juku. The early start laid the groundwork for what would become a lifelong dedication to combat sports and a deep technical foundation in grappling.
During her school years, Watanabe continued to develop her judo at Shibuya Kyoiku Gakuen Shibuya Junior High School and later at Shibuya Kyoiku Gakuen Shibuya High School. In her first year of high school, she placed fifth at the National High School Championships, and in her second year, she reached the final of the Kinwashi-ki competition, finishing second. She went on to capture a silver medal at the Inter High School Championships in the individual event and a bronze medal in the team competition. In her junior year, she won the Asian Junior Championships, confirming her status as one of Japan’s top young judo athletes.
Watanabe later attended Tokai University, where she continued her competitive judo career. In her freshman year, she won the All-Japan Junior Championships, and she continued to place at major events including the Kodokan Cup. After completing her studies, she joined JR East in 2011, where she contributed to the team’s second-place finish at the 2016 Jitsugyo team competition and earned the Outstanding Player Award. Eventually, after a brief stint as a judo coach, she made the decision to pursue mixed martial arts.
Path to MMA
Watanabe’s path to mixed martial arts began after she retired from competitive judo and briefly served as a coach. She felt that she could not continue training athletes while believing she had not yet reached her own potential as a competitor. After only three months as a coach, she joined Fighter’s Flow, a gym run by mixed martial artist Takao Ueda, and committed fully to MMA in 2017.
Her transition was aided by her柔道 background, including a 4th dan black belt, which gave her a strong base for the grappling-heavy aspects of mixed martial arts. In 2017, she also appeared on KUNOICHI, the female version of SASUKE aired on TBS, twice in a row, achieving top results in both appearances. The experience added to her public profile in Japan before she stepped into the cage as a professional mixed martial artist.
