Juko Ryu Aiki JuJutsu
History Of Juko Ryu Aiki JuJutsu
Tenshin Shinyo Ryu is noted for its effective use of grappling techniques , its use of shime waza (strangles/chokes), kansetsu waza (joint locking) and kyosho jutsu waza (atemi to the vital points) with its roots in a combination of Yoshin Ryu and Shin no Shinto Ryu.

Yoshin Ryu is one of the older schools of ju jutsu and was founded some time before 1651, although the exact date is unavailable. The founder of this school was Akiyama Shirobei Yoshitoki who was a doctor and had allegedly studied in China, bringing back with him three martial techniques. The legend goes that while he was meditating at the Dazaifu Tenmangu shrine for a period of one hundred days, he devised three hundred additional techniques.

Shin no Shinto Ryu was devised much later, some time in the late eighteenth century, by Yamamoto Tamizaemon Hidehaya, a guard at Osaka castle. He too had studied Yoshin Ryu on which he based his system.

The Tenshin Shinyo Ryu was created by Iso Mataemon Masatari. Born in 1787 under the name Okamoto Hachiroji, he studied Yoshin Ryu and Shin no Shinto Ryu. When he had mastered these arts, he went on a Musha Shugyo, a journey around Japan to take part in duels and shiai (or matches). It is said that he was undefeated but it is certain that he developed Shin no Ate, which is the use of body parts as weapons. He was later appointed as ju jutsu teacher to the Kobusho, which was the martial arts school for the Tokugawa Shogunate.

In 1897 Gunji Koizumi studied under Nobushige Tage, a Tenshin Shinyo Ryu teacher, and in 1904 he continued his studies of Shin Shin Ryu under a retired samurai of the Owari clan, called Nobukatsu Yamada. Koizumi arrived in Britain in 1906. He left to study engineering in the USA, but returned in 1910 to the United Kingdom where he stayed until his death on 15th April 1965.

Although a ju jutsu exponent, Koizumi adopted the Kodokan syllabus in 1920, reserving his teaching of ju jutsu to selected students only. One of these was Geoff Watts who became a very close friend of Koizumi. In 1968 the former took on a new student, Keith Morgan, who was the only student to whom he taught ju jutsu.

In the furtherance of his studies, Keith Morgan studied the principles of Hakko Ryu under Irie Sensei, the head instructor of this school. Hakko Ryu has its roots firmly in Daito Ryu Aiki Ju Jutsu. Keith Morgan named his schools Juko Ryu Aiki Ju Jutsu to reflect the underlying philosophy and influences, which is not to be confused with the Jukokai of R. Sacharnoski. Keith Morgan continues his studies with further research into the Koryu system and Eishen Itto Ryu Batto Jutsu.

Sensei Mark Whitehead carries on this tradition through the guidance of Shihan Keith Morgan founder.
