Sokaku Takeda was born in 1868. He is regarded as the most modern and prolific teacher of Daito-ryu Aikijujitsu. According to his enrollment books, Takeda taught as many as 30,000 students. He died in 1943, but his legacy continues. Students of note include Morihei Ueshiba and Kodo Horikawa. Ueshiba is the founder of Aikido. Horikawa, founder of the Daito-ryu Kodokai, was the teacher of Seigo Okamoto.
Kodo Horikawa was a top student of Sokaku Takeda. Takeda taught Horikawa according to his body type. Thus, it is said that Horikawa's technique emphasized Aiki over strength. Horikawa received Kyoju Dairi directly from Sokaku Takeda. It is said that Takeda gave permission to scribe his own Menkyo Kaiden certificate, but sadly passed away before he could sign. Thus, Horikawa received Menkyo Kaiden from Sokaku's son, Tokimune. Horikawa passed away in 1980.
Soshi Seigo Okamoto began training in Daito-ryu Aikijujutsu in 1963, under Kodo Horikawa. Okamoto founded the Daito-ryu Roppokai in 1980, after the passing of Kodo Horikawa. Soshi Okamoto is a true master of Budo, and the subtlety of his technique astounds. I am honored to study this Budo, and to be given permission to operate an official Group.
