History of 

Founder’s Message

​

Manakai Martial Arts was founded in 1990 from a lifelong connection with Japan and a deep respect for the principle of Kaizen—continuous improvement.

​

My training in traditional Japanese Bujutsu, particularly the teachings influenced by the Tenshin Shōden Katori Shintō-ryū, revealed to me that true martial arts are not static systems. They are living traditions, grounded in riai—the integrity of principle—where technique, realism, and personal development evolve together. This understanding was reinforced by many outstanding teachers and by my own experiences training throughout Japan, as well as in China, the Philippines, and Thailand.

​

Manakai was created to honour this way of learning. Its name reflects the idea of studying deeply and absorbing knowledge broadly, like an ocean. While rooted in traditional martial disciplines, Manakai is not confined to them. It embraces both classical and modern martial arts, recognising that improvement comes through examination, experience, and refinement—not through blind preservation or rigid adherence to form.

​

Through my own journey, I came to understand Bujutsu as the martial art we practise, and Budō as the way of life we cultivate through that practice. Manakai exists to support both. It encourages practitioners to refine their skills, expand their understanding, and contribute meaningfully to the ongoing development of the art.

​

Martial arts, like life itself, are in constant motion. Nothing remains fixed; everything is becoming. Manakai Martial Arts stands as a system that respects tradition, embraces growth, and invites each practitioner to walk their own path with integrity, discipline, and purpose.
