An Introduction
Samurai. The word brings up an image of the Japanese warrior, their culture and the martial arts of Japan. The Samurai to this day carry a reputation of indomitable warriors and the weapons they used, particularly the sword, are a source of interest if not outright fascination. How did the Samurai train to become the warriors they were with a reputation that has carried on through centuries?
Tenshinshō-den Katori Shintō-ryū was founded by Iizasa Choisai Ienaō during the mid Muromachi era (1336-1573) in the Katori region of Shimōsa province (present-day Katori city, Chiba prefecture), and is the source from which many Japanese martial arts have evolved.
Iizasa Choisai Ienao (Choisai-sensei), at approximately sixty years of age, undertook a retreat of a thousand days at Katori Jingu (Katori Shrine). This retreat consisted of purification, prayer and austere training devoted to Futusnushi-no-Kami, the Deity of Katori Jingu. It is said that the Deity then presented him with a divine scroll on the warrior and military arts. Since the art was received through divine transmission, Choisai-sensei named it “Tenshinshō-den” (direct and authentic transmission from the deities) Katori Shintō-ryū. The tradition has been handed down to the present day.
