& CHINA
Inheriting Tradition, Connecting the World.
The Gateway to the Birthplace of Kyokushin.
ABOUT KWF
JAPAN & CHINA
In January 2025, the KWF Japan representation was officially transferred and unified under the Kyokushin Hamai Group, marking a historic milestone in the evolution of Kyokushin karate.
Under the leadership of Mika Hamai, who now serves as the Representative for both KWF Japan and KWF China, this unification creates an unprecedented bridge between the domestic Japanese karate community and the global Kyokushin World Federation.
This transition follows the visionary legacy of the late founder Shikan Noriyasu Hamai, who established KWF China and championed international expansion. Today, his vision lives on through unified leadership that fosters authentic exchange between the birthplace of karate and practitioners worldwide.
We are the legitimate representative of the birthplace of Kyokushin, connecting tradition with global excellence.
