In China during the Toh-Era, there lived a woman named En-no-
Kyojo (En was an ancient Kingdom in Toh, Kyo was the capital
city of En, no is of) who was renowned as the expert martial
artist of Koppo-jutsu, Daken-jutsu, Shorin-Ken and Hicho-jutsu.
According to legend In the Toh Era under the rule of Chusou
Shinryu, during an auspicious new year, a Cho Shousou rose up
with an army of several hundred soldiers and savagely attacked a
village. Amidst this violence, En-no-Kyojo stood up and with
Fudoshin (unmoved heart, immovable spirit) and a smile, she
valiantly defended against the army with unarmed techniques and
was able to heroically rescue the village people. En-no-Kyojo
taught to Ryu Enpi (Kokuido Kenji). Ryu Enpi was the specialist
of not only Daken-Jutsu but also Ken-Jutsu and So-Jutsu. It
seems that he had learned ancient Japanese swords techniques
(Wa-Ken). In the Eikyu Era (1113 – 1118), these martial arts
came into Japan, and were taught to Izumo Kajya Yoshiteru
(Minamoto Hachiman Shichiro Tamenari).
