Daito-ryu Aiki Jujutsu is a classical school of jujutsu, or system of unarmed fighting, developed to defeat both armed and unarmed opponents. Daito-ryu was a private martial art transmitted for generations within the Takeda family of the Aizu domain, and later disclosed to the public by Takeda Sokaku in the late 19th Century. The Daito-ryu technical tradition includes both jujutsu and aikijujutsu, but a clear distinction is made between the two and the emphasis is strongly on the latter. From ancient times the admonishment to "attack where the opponent has been unbalanced" has been a fundamental axiom of Asian martial arts. In Daito-ryu, the principle of "how to unbalance the opponent" is referred to as “aiki,” and a great many of the tradition's oral transmissions and secret teachings pertain to the various aspects of these strategies.

Today, Daito-ryu Aikijujutsu is a cultural heritage of the Japanese warrior class, with a long history and tradition. The mainline school lineage was inherited by Takeda Tokimune (son of Takeda Sokaku), and then passed to Kondo Katsuyuki (Menkyo Kaiden). In 2020, the headmastership of the mainline tradition was passed to Kondo Masayuki (Menkyo Kaiden) and currently has a following in Japan, Hong Kong, UAE, Australia, Bulgaria, Germany, Holland, Italy, Serbia, Slovakia, Switzerland, Russia, United Kingdom and the United States.

Daito-ryu Aikijujutsu holds regular membership in the Association of Japanese Traditional Martial Arts (Nihon Kobudo Kyokai) and the Association for the Promotion of Japanese Traditional Martial Arts (Nihon Kobudo Shinkokai). Each year the leaders and representatives of the school participate in Japan's premier martial arts demonstrations, held at the Nippon Budokan, Asakusa Riverside Sports Center, Meiji Shrine, Kashima Shrine, and other locations throughout Japan.
