This is the first book in English to introduce the technical curriculum of Daito-ryu Aikijujutsu as originally taught by Sokaku Takeda. It contains the 31 techniques of the ikkajo series of the Hiden Mokuroku, the first level of study in Daito-ryu. The arts of Daito-ryu form the basis for most of the techniques of modern aikido, the martial art created by Morihei Ueshiba O-Sensei. The international success of aikido has in turn rekindled great interest in Daito-ryu and the legendary figure of Sokaku Takeda.
The author, Katsuyuki Kondo, was born in Tokyo in 1945. He began his training in Daito-ryu aikijujutsu as a teenager under Tsunejiro Hosono and later Kotaro Yoshida, a friend and senior in Daito-ryu to Morihei Ueshiba. With an introduction from Yoshida, Kondo made periodic visits to Hokkaido starting in 1961 to practice under Tokimune Takeda Sensei. He continued his training under the Daito-ryu headmaster for 32 years.
