Seido means 'Sincere Way' and aims to develop students not just physically but also mentally, helping create 'complete' and 'balanced' individuals committed to improving themselves and the communities they live in.

Seido karate's three main principles are Respect, Love and Obedience. Love for one's family and friends. Respect for your fellow karate ka, your seniors, your parents and their knowledge and experience. Obedience (not subservience) to the laws and moral rules of life. Seido is headquartered in New York City, but has many branch dojos around the world.

An important part of the Seido World Seido Karate Organization is the Seido Juku Benefit Foundation which performs many good works for charity, including the annual benefit tournament. Nakamura has received praise and recognition from City, State, National and International leaders for the good works of the benefit foundation.


On April 5, 1966, the head of Kyokushin Karate, Masutatsu Oyama, selected Nakamura to go to the U.S.A. and spread the spirit of karate. Aged 24 (just one year after he graduated university) he moved to New York to begin teaching Kyokushin Karate. His first dojo was at the Brooklyn Academy of Music. In 1971 established the North American Kyokushin Karate headquarters. Over the next ten years he served as the American head of Kyokushin Karate. He trained many students: Thomas Wiggins, Claude Battle, Charles Martin, William Best, Michael Reeves and William Oliver were some of his students.

As the Kyokushin style became more popular, Nakamura started to feel the quality of the instruction was slipping. He also began questioning the philosophy of his mentor Mas Oyama. In 1976 he respectfully withdrew from Kyokushin Karate, severed links with the Japanese Karate world and established his own style, Seidō juku.
