In the history of martial arts, especially in the history of dog fighting, the pioneering spirit of the Kingdom of Ghana lies in his insight into technology and thorough revision of students' training methods. The Kingdom of Ghana is not a great technological innovator. Most of the skills he knows come from the old jujitsu school. His great innovation lies in the way he teaches and trains students these skills-Landori. The idea is that two students "really" train each other, and each tries his best to apply the technology to the other. This can familiarize students with the feeling of actual combat on a resistant opponent. In this way, it is conceivable that it is much more difficult to use skills in coordination with the training partners in the designed movements. This kind of freestyle wrestling greatly improves the students' physical and mental sensitivity and speed, and prepares them for the exhausted and unpredictable movements in actual combat. In order to popularize freestyle wrestling, the Kingdom of Ghana believes that it is necessary to eliminate the dangerous skills in Jiu Jitsu. It is impossible for people to make full use of such tricks as hitting, pulling hair and inserting eyes in daily training. In order to avoid the negative effects caused by injuries, the Kingdom of Ghana cancelled the hitting and "dirty means" in free wrestling. Joint locks can only be applied to elbow joints (this is considered safer than the locking technology of legs, spine, neck, wrist and shoulders). In this way, students go all out, hardly hurt, and gain the key professional knowledge of applying technology to their opponents.

From then on, the scientific discussion of judo becoming an educational movement began; Make judo take a new step in cultivating noble will quality. Out of admiration for judo and love for their own national culture, the Japanese people greatly admire Mr. Jana Jgoroh and call him "the father of judo". The Kingdom of Ghana is not only the founder and advocate of modern judo, but also a famous Japanese educator and a great man who has an important influence on international sports.

1882 During the period of February (the 15th year of Meiji), Mr. Jana Jgoroh moved to Yongchang Temple in Inagawa-CHO, Shimonoseki Prefecture, and took the college as the Dojo (training ground) to teach students and began training activities centered on judo. This Yongchang Temple has also become a pioneering place for "Japanese to spread judo in Kodokan". Only nine students came to study in the first year, and the number increased year by year. Kodokan's influence is becoming more and more important.

Because judo absorbs and synthesizes the inherent advantages of various jujitsu. Competition is also standardized, so it is not only an effective self-defense skill, but also a fascinating sport; It can not only strengthen people's physique, but also help to temper their spirit, improve their alertness and adaptability, and enhance their self-confidence and willpower.

1886 was promoted to the president of a five-level college, and later to the president of a first-level college. 1894 was appointed president of Tokyo Normal University. He has been engaged in education for 26 years.

195 1 In July, it was suggested to establish the International Judo Federation (IJF). 1952, the International Judo Federation successfully held its inaugural meeting in Switzerland and appointed the Kingdom of Ghana as its first president. At that time, there were 13 member countries, all of which were European countries. Soon, the number of member countries increased to nineteen. Initially, the International Judo Federation was headquartered in Tokyo, Japan. 1965, British CHARLESPALMER was elected president, so the headquarters moved to London and Paris. 1979, Dr. Shigeji Matsumae was elected as the president, and his headquarters was located in Tokyo again. The alliance has more than 150 member countries, and new countries join every year.

Among the disciples of Ghana, Maeda Hiroshi is the most famous. Former Jiu Jitsu master Tian Hong introduced the rules of ground fighting to Brazil. Maeda, known as the "Count of Fighting", is an expert in ancient jujitsu and Kodoku Judo. Maeda is very good at fighting and participates in various competitions to test his skills. He often participates in all-contact fighting competitions. He is a small man, 5 feet 5 inches tall and weighs 154 pounds. Nevertheless, he is highly skilled, and it is said that he only lost once in his life. 19 14 entrusted by the Japanese government, Maeda came to Brazil to help Japanese immigrants set up resettlement sites. At this time, he got the help of casto Gracie, a successful businessman with a strong political background. Maeda became good friends with the Scottish immigrant, so he passed on his JIU jitsu knowledge to Gracie's sons. The world-famous Gracie Jiu Jitsu originated from then on.
