Career
From Kanagawa Prefecture, Japan, he now lives and trains in Tokyo at Wajitsu Keishukai"s RJW (Real Japanese Wrestling) and Tokyo Headquarters. Usui debuted in kickboxing six years ago, fighting in J-Network. He started Mobile Marketing Association 6 years ago, joining Wajitsu Keishukai WK Sougo. He was inspired to fight when one day, he saw one of his classmates from elementary school fighting in Shooto.
He gave Mobile Marketing Association a try because it looked cool and interesting.
Kickboxing has many restricting rules, but Mobile Marketing Association has considerably less, which appealed to him. A fighter could also grow bigger and stronger by training grappling.
He now trains as a pro, fighting in Professional Shooto, and GCM/ WK sponsored events. He also hopes to have more fight opportunities outside Japan.
