Kempo Jujitsu is an efficient and practical martial art for self-defense; it is the ideal martial art for the modern world. According to the World Health Organization, more than 300 million people worldwide are physically active. Of these active individuals, about 3% are black belt level practitioners of a traditional martial art. The fact that so many normal people can defeat trained police officers in street fights proves that martial arts are still relevant today. The effectiveness of Kempo Jujitsu as a self-defense technique is based on three factors: its simplicity, its diversity, and its scientific basis. Because Kempo Jujitsu is simple to learn but difficult to master, it is capable of defeating almost any opponent. The variety of techniques available makes it impossible for your attacker to predict what will happen next. This element of surprise helps ensure that you will prevail in most situations. Finally, the scientific basis of Kempo Jujitsu makes it highly effective. Modern karate masters study under one of the greatest authorities in the history of the art, Mr. Honshu Kanai, who founded the Honshu Dojo in California. They continue to learn from him and other senior teachers within the dojo family.
