For the next several hundred years, the martial arts were refined by Samurai who made a lifetime study of some twenty or thirty martial arts. Of these arts only one was based on weaponless self defense -- jujitsu. By the mid-1800's more than 700 different jujitsu systems existed. The most popular were takenouchi-ryu, jikishin-ryu, kyushinryu, yoshin-ryu, mirua-ryu, sekiguchi-ryu, kito-ryu, and tenshin-shinyo-ryu; the last two were instrumental in Judo's development.
It was during this time that Japanese politics disintegrated into disarray. Commodore Perry's visit to Japan in the mid-1850's also changed Japanese civilization by opening up a new world to them.
In 1868 Imperial rule was restored (Meiji Restoration) and the decline of the Samurai class started along with a rapid decline in all martial arts. Although the government did not officially ban the martial arts, people were not encouraged to learn or practice them since the state was considered more important than the individual. Jujitsu literally fell into disuse. What was once the glory of the samurai was now looked down on and many well established jujitsu schools began to disappear.
If the budo concept was to survive the Meiji Restoration, it had to change and become a tool to cultivate an individual and make him a better person for the good of all. As a result budo found a home in physical education and sport.
Sport provided teamwork which was good for all and also developed the individual. It was a complete physical education; not just a game. Although self defense techniques were included in the training, emphasis was on using the techniques in a holistic manner. Dr. Jigoro Kano is credited with jujitsu's survival of the Meiji Restoration. He took jujitsu and adapted it to the times. His new methodology was called Judo.
In 1882, Dr. Jigoro Kano (The Father of Judo) made a comprehensive study of these ancient self defense forms and integrated the best of these forms into a sport which is known as Kodokan Judo.
