Takeda Sokaku's third son, Tokimune Takeda (武田 時宗 "Takeda Tokimune", 1916–1993), became the headmaster of the art following Sokaku's death in 1943. Tokimune taught what he called , an art that included the sword techniques of the Ono-ha Ittō-ryū along with the traditional techniques of Daitō-ryū Aiki-jūjutsu.

Tokimune Takeda died in 1993 leaving no official successor, but a few of his high-ranking students, such as Katsuyuki Kondo (近藤 勝之 "Kondō Katsuyuki", 1945–) and Shigemitsu Kato, now head their own Daitō-ryū Aiki-jūjutsu organizations.
