Legends

The history of Daito-ryu up until the end of the Edo period is based on scrolls and oral traditions passed down from Takeda Sokaku and Takeda Tokimune. According to them, the name "Daito-ryu" originated about 900 years ago from Shinra Saburo Minamoto Yoshimitsu (1045-1127), who could be considered the school's distant ancestor. As a child, Yoshimitsu lived in the Daito mansion in Omi and was also called Daito Saburo. The name "Daito-ryu" is based on this.
Shinra Saburo Minamoto Yoshimitsu studied military science such as
Sun Tzu

and Wu Tzu, served the Imperial Court as Sahyoe no Jō, and was a famous general in both literature and martial arts who mastered the ways of sumo and aikido. The aikido that Yoshimitsu perfected was an ingenious addition to the secret techniques passed down in the Genji family. If we trace the origins of aikido back to the ancient Tegoi (hand-begging). The Kojiki, one of Japan's oldest books, tells the story of Takemikazuchi-no-Kami taking Takeminakata-no-Kami's hand and "grabbing it as if it were a reed and throwing it with his sword."
This tego is said to be the beginning of sumo, and has been passed down from the legends of
Nomi no Sukune and Taima no Kehaya, who appear in the Nihon Shoki, to the sumo festivals held at the Imperial Court during the Heian period and samurai sumo during the Kamakura period. Sumo festivals would bring together wrestlers from all over the country to wrestle in front of the emperor, but unlike today's sumo, there was no sumo ring and it had a strong martial arts element that originated from tego. This can also be seen in the imperial edict of
Emperor Ninmyo (810-850), which states, "Sumo is not merely entertainment. It is the practice of military force that is the most important part of it."
In the 10th year of the Jogan era (868) of
Emperor Seiwa (850-880), the Sumo Festival, which had previously been under the jurisdiction of the Ministry of Ceremonies, was transferred to the Ministry of War, and sumo took on a more martial arts character. The form of protecting the emperor by begging was inherited by the

clan, beginning with Emperor Seiwa's grandson, Prince
Minamoto Tsunemoto, and continued from Tsunemoto to
Minamoto no Mitsunaka, Yoriyoshi, and Yoshimitsu.
Yoshimitsu was appointed Kai no Kami for his military achievements in the Gosannen War, and in his later years, he trained his mind and body at the Onjoji Esoteric Buddhist training hall under the name of Oyabu Nyudo, and is said to have mastered invincible supernatural powers and divine inspiration. This was the origin of Daito-ryu, which broke away from the so-called begging.
Yoshimitsu gave his second son, Yoshikiyo, the flag and armor handed down from the Minamoto clan and made him his successor. During the time of Yoshikiyo's grandson,
Takeda Nobuyoshi (1128–1186), he is said to have lived in Takeda Village, Kitakoma County, Kai Province, and took the name of Takeda. This was the beginning of the Kai Takeda clan, which would later be linked to
