大東流合気柔術
The technical curriculum of aikido was derived from the teachings of Takeda Sōkaku; the basic techniques of aikido stem from his Daitō-ryū system. In the earlier years of his teaching, from the 1920s to the mid-1930s, Ueshiba taught the Daitō-ryū Aiki-jūjutsu system; his early students' documents bear the term Daitō-ryū. Indeed, Ueshiba trained one of the future highest grade earners in Daitō-ryū, Takuma Hisa, in the art before Takeda took charge of Hisa's training.
