Sekiguchiryu originated over 450 years ago around the 1560 

Thus, it was "born in a baptism of fire" during the peak of the bloodiest Wars 

known as "Sengoku Jidai" The Age of Warring States period.



This system was developed by a man named Sekiguchi Ujimune.

He was more widely known as Sekiguchi Jushin, (same person as above picture). 

Sekiguchi Family was part of the famous Seiwa Genji descendants 

from the Minamoto's bloodline 12th Century.

Sekiguchi Jushin that served Imagawa Clan during the Sengoku Jidai 1467-1603 

Period.Age of Warring states. When the once powerful Imagawa family fell to the conquests of Oda Nobunaga at the Battle of Okehazama in June 1560.

Jushin devoted his life to martial arts. He left the castle of his lord for the Atago Mountains located just outside of Kyoto region, where he underwent intense physical and spiritual training in Shugendo religion, A form of Esoteric Buddhist practice's and nature worship. 

The result of that training became known as Sekiguchiryu  

Rumours of this wanderer and his unique art rang out throughout the country.


Sekiguchiryu was a favored combative system of the Tokugawa Shogunate.

Jushin was part of the famous Imagawa clan and his aunt was wife to Tokugawa Ieyasu.

Therefore Sekiguchiryu remains close in connection to the Tokugawa regime. 


When Tokugawa Yorinobu, head of the Kishu Han 

(modern day Wakayama Prefecture) heard about Jushin Sekiguchi and after meeting him, 

Jushin was asked to become a permanent guest at Wakayama castle and to teach his Sekiguchiryu 

to the Samurai-retainers there. 

Even the 8th Shogun, Tokugawa Yoshimune (1684–1751) 

was a practitioner of Sekiguchiryu he had attained (Menkyo -Kaiden) in the system.  

Sekiguchiryu is most known for its Ju-Jutsu.

Jujutsu focus is on perfection of effortless technique, over brute strength

thus allowing for a smaller and weaker person to control a physically stronger person.

According to scrolls the word Jujutsu and fighting skills  -

was the invention of Jushin Sekiguchi himself, before this unarmed techniques were referred to as Yawara or Kumi-uchi or Taijutsu also the term and concept "Ukemi" evasion / reversal of techniques when applied all involved from Jushin Sekiguchi observations of a cat falling down from a roof  

the cat always seems to land safely on its feet, because of its ability to tumble in mid air.

Today the word Jujutsu is now widely used as a name for unarmed 

fighting methods in most Japanese martial arts. 

At its peak Sekiguchiryu contained all aspects of Samurai Warfare.

Now however a lot of its fighting methods are contained only within handed down historical scrolls.
