Tokugawa made Edo (Tokyo) his capitol. Tokugawa brought the Daimyos, administrators as well as the Emperor and his court under the control of the Shogunate. Tokugawa isolated Japan form the Western World.
In 1612 Christians became subject to official persecution resulting in a number of massacres. In 1624 the Spanish were refused entry to Japan and travel abroad was banned, as was the building of large ships. The only Europeans allowed to remain in Japan were a group of Dutch traders who were restricted to an Island in Nagasaki Harbour, even they were not afforded any protection and their persecution continued.
From this period and onwards we can find more details relating to the development of Ju-jitsu. Fukuno Schichiroemon founded the Kito-Ryu, a style emphasising throwing techniques and kata. Terada Kanemon founded Jikishin-Ryu. Both Fukuno and Terada developed their systems in the mid 17th century. Other prominent systems were Sakiguchi-Ryu, Yoshin-Ryu, Miura-Ryu and the Tenin-Ryu. Yoshin Miura founded the Yoshin-Ryu and he devised many arresting techniques, after his death his students continued to develop his system. Matayemon Iso who was a student at the Yoshin-Ryu founded the Tenjin-Shinyo-Ryu.
In 1695 a Chinese priest by the name of Chin Genpin became a naturalised Japanese and brought Kempo to Japan. At this time other forms of Ju-jitsu were already in practice in Japan; therefore Genpin couldn't be credited with the introduction of Ju-jitsu to Japan. However, Genpin thought 3 ronin (masterless samurai) who subsequently developed the Kito-Ryu. Some time later Inugami Nagakatsu founded the Kiushin-Ryu and it is believed this is a derivative of the Kito-Ryu.
Feudalism remained static during the next 200 years. Also during this time the Lords and lesser nobility as well as the Samurai adopted the standards of the feudal warriors (Bushido). Without outside influence extreme nationalism developed through out Japan. It was during the 18th century that a large wealthy merchant class developed great strength and impoverished landless peasant's disturbances became more frequent. In 1720 Shogun Yoshimune allowed the study of European books and by the early 19th century visits from Europe were allowed although they were still officially band.
In the early 19th to mid 19th century there were a number of Americans' shipwrecked around the Japanese Islands; when the seamen were rescued by the natives they were held captive. While the American's were trying to free their countrymen they were also interested in developing friendship and trade with Japan. In 1853 the American government sent a large mission, headed by Matthew Calbraith Perry, to Japan; a large fleet of American war ships protected this mission. In March 1854 the United States and Japan signed a treaty. There were still antiforeign warlords who resisted foreign trade and it was not until a show of foreign power in 1864 that things stabilised and the power of the Shogunate started to wane. With the decline in feudalism, that was eventually abolished in 1860-65, Jujitsu became less popular and fell into disuse almost becoming extinct.
To the south of Japan lie the Ryukyu Islands of which Okinawa is the largest. Up until 14th century they enjoyed independent government. Between the 14th and 19th centuries China, who first invaded them in the 7th century, dominated the Islands. Japan invaded in 1609 and both they and China demanded tribute payments from the Islands Government. In 1879 Okinawa became part of Japan when they dethroned the Ruler of the Islands.
