MUSO JIKIDEN EISHIN RYU traces its lineage back to the mid 1500's where Hayashizaki Jinsuke Shigenobu (1546-1621), a retainer of the Mogami clan, is deemed to have invented or repopularised what we now know as Iai.


The original techniques of the school were added to by Shuze Hasegawa Eishin almost two hundred years later. These techniques were primarily concerned with combat from tate-hiza, a posture adopted for sitting when wearing armour.


Omori Rokurozaemon Masamitsu, a swordsman of the Yagyu Shinkage Ryu, was responsible for adding another set of techniques executed from the formal sitting position of seiza. Seiza was becoming a more popular method of sitting indoors during this period, due to the influence of the Ogasawara clan.

Oe Masamichi [pictured left] 1852-1927 was the last undisputed headmaster of this line. He took the techniques of Omori Ryu and Eishin Ryu and combined it with the Tanimura-Ha to form Muso Jikiden Eishin Ryu. Oe sensei was notably also the 15th generation headmaster of the Shimomura-Ha before becoming 17th headmaster of the Tanimura-Ha. Oe sensei was said to have been influenced by his combative experiences in the Hamaguri Gomon no Ikusa (The Clam Gate War). Oe Masamichi never named a successor to continue the lineage, however several of his students did receive Menkyo Kaiden (certificates of total transmission).

 
 

Iwata Norikazu [pictured right] 1913 - 2011 was the Kaicho of Zenkoku Roshukai until his recent sad death, an organisation created to pass on Muso Jikiden Eishin Ryu as taught by Oe Masamichi. Iwata sensei studied under several of Oe Masamichi's direct students, and held Menkyo Kaiden in the system, as well as Hachidan Hanshi status. Iwata sensei was highly regarded as both a swordsman and historian. His successor is still to be announced.
