As the Official Representative for both KWF Japan and KWF China, Mika Hamai serves as a bridge between authentic Japanese Kyokushin and the international community. Her fluency in Chinese and deep understanding of both Japanese and Chinese cultures enables effective transmission of Kyokushin principles across continents.
She presides over the Karate school in Tokyo, operating three dojos in Nakano-sakaue, Yoyogi-uehara, and Yotsuya, teaching approximately 300 students with a focus on accessibility for children and beginners while maintaining rigorous technical standards.
As a key member of Kyokushinkaikan So-Honbu (the original headquarters), Mika Hamai is actively working to revive the original essence of Kyokushin from the Sosai Mas Oyama era. This involves preserving authentic teaching methods, emphasizing fundamental techniques (Kihon), and maintaining the philosophical foundations that made Kyokushin a transformative martial art.
Her approach prioritizes quality of human character over quantity of students, and mastery of basics over flashy techniques—a stance that distinguishes the Hamai Group in an era of commercialized martial arts.
Mika Hamai has a proven track record in Japan's top full-contact karate organizations, including JKJO (Japan Karate-Do Organization) and JFKO (Japan Full Contact Karate Organization). Her students consistently produce strong results in national-level competition, demonstrating that traditional training methods yield superior technical outcomes.
Her own competitive achievements include appearing in the World International Karate Championship as a member of the Japan National Team (2002) and completing the legendary 30-person Kumite sparring (2011), earning her 3rd Dan at that time.
Started learning karate at the Kyokushinkaikan Ishikawa headquarters, establishing the foundation for her lifelong dedication to the art.
Appeared in the World International Karate Championship as a member of the Japan National Team, representing Japanese Kyokushin on the global stage.
After graduating from Chuo University, went to China and engaged in the establishment and operation of the Dalian headquarters for approximately 4 years, laying the groundwork for the Hamai Group's international presence.
Completed the legendary 30-person Kumite sparring and achieved 3rd Dan, demonstrating exceptional endurance, technique, and fighting spirit.
Worked at Recruit (currently RLS) for 4 years, gaining business experience that would later inform her approach to dojo management and international operations.
Launched her own Karate school in Tokyo, establishing a new model for traditional Kyokushin instruction that balances accessibility with uncompromising standards.
Assumed leadership of the Kyokushin Hamai Group after the passing of Chairman Noriyasu Hamai, taking on the responsibility of preserving his legacy and the authentic Kyokushin tradition.
Continues to lead the Hamai Group with a focus on quality over quantity, serving as Official Representative for KWF Japan and KWF China, and working with Kyokushinkaikan So-Honbu to revive the original essence of Kyokushin.
"In today's world, there is a tendency to avoid discipline, even in education. At each of our branches, I ask instructors to properly guide students and, when necessary, correct their behavior and mistakes."
"It is acceptable if the Kyokushin Hamai Group is known for its strict instruction. I believe this is one of our roles in society."
— Mika Hamai, Representative

Engagement with visual arts, reflecting an appreciation for aesthetic principles and cultural expression.
Exploration of different cultures and continued study of Chinese language and culture.
