Seido Karate

Seido Karate was founded by Kaicho (Chairman) Tadashi Nakamura. Kaicho Nakamura came to New York City in 1966 to bring the Kyokushin Karate style of Sosai (President) Masutatsu Oyama to the United States, but eventually began to find differences in philosophy with his longtime mentor. In 1976 Kaicho Nakamura respectfully withdrew from the Kyokushin-kai and began to build Seido Juku, "the school of the Sincere Way". (More...)
