Kokorokan
Kokorokan is a karate style which broke off from Seidō juku in 1987, in an attempt to find a middle ground between the old style Kyokushin and Seidō.
History
Kokorokan Karate originated from the traditional form of Karate called Kyokushin. Tadashi Nakamura is responsible for bringing Kyokushin to the U.S. from Japan. Because of the physically demanding style of Kyokushin karate, he slightly changed its style and methods of discipline upon introducing it to America. Seidō Karate was founded in 1976 by Nakamura in upstate New York. Eventually, due to differences of opinion, some of the original founding students of Seido, not including Nakamura, broke off from the organization, starting new forms of Karate, one of which became Kokorokan.
Frank Rossetti was the main person responsible for creating Kokorokan, after breaking off from Seidō. Rossetti opened his new dojo in Troy, NY. His intention in creating Kokorokan was to find the middle ground between Kyokushinkai and Seidō. Kokorokan is extremely similar to Kyokushinkai and Seidō as far as certain techniques go, such as self-defense techniques, katas, and class format.
Rossetti still runs the original dojo in Troy, NY, with Jeff Dooley, an original Kokorokan student. Several Kokorokan dojos can be currently found throughout the United States.
