We also train in Kuniba Ryu Goshin-do which is, through Shogo Kuniba, Soke a mixture of Aikido, Judo, Jiu-jutsu and Karate-Do. With Kuniba, Soke's vast knowledge on the different arts (see site titled Soke), he was able to combine the different arts where there was a weakness. In other words he made Goshin-do to fit all situations, with principle.
Shogo Kuniba, Soke was never anything but a martial artist. He was always free to train and experiment with the budo, to create and innovate. He had trained with the greatest masters of the time in karate, judo, aikido, and kobudo. So it is not surprising that Kuniba, Soke was able to develop a powerful style of his own.
In 1971, Kuniba, Soke was invited to the United States for the first time. In subsequent years, he came to America to teach his style of karate. Each year he stayed longer, noting with some concern the difference between applying Japanese techniques on the brawny Americans and then returning to Japan to rethink his techniques. Gradually, he began to favor what he called Goshin Budo over pure karate-do. To him, Goshin Budo was applied self-defense technique. So, he taught a combination of judo/jiu jitsu and aikido in an unlimited array of self-defense scenarios.
From 1971 to 1982, Kuniba, Soke traveled back and forth from Osaka to the United States. In the U.S. he would experiment; in Japan he was expected to "act like a Soke." In other words, his followers in Japan weren't very interested in any deviation from kihon, kata, and kumite. This he found frustrating. By 1983, he had turned things around. He moved to the U.S. and often traveled back to Japan to carry out his Kaicho/Soke functions at the Seishin Kai world tournament. As far as he was concerned, his new art was a product of his new home, America.
Seeing that Goshin Budo was a hit in America reinforced his desire to teach it, and to continue to develop it. The only major problem was that his students in the U.S. did not have his depth of background, nor his genius for technique. Naturally, confusion set in. Too many techniques, too many combinations, too many possibilities; students left his clinics impressed, but confused. Then the solution came to him: Kata. Realizing that he could best convey the essence of his new arts by means of the kata approach, he set out to create Goshin Budo Kata on five levels: Shoden (I-V), Chuden (I-V), Okuden (I-V), Kaiden (I-V), and Menkyo (I-III). Each series is progressively harder, but the structured approach allows for easier acquisition by the student.
Seeking and obtaining authentication by the Japan Karate Federation (J.K.F), Kuniba, Soke gained acceptance of his new art, not as a rival to existing karate styles, but as an entirely new and compatible approach to self-defense.
With the kata approach implemented and J.K.F. approval, Kuniba, Soke decided to make his new art known as Goshin Do, rather than Goshin Budo. The full name of the art is: Kuniba-Ryu Goshin Do.
