THE ORIGINS
Going back to the origins of Aiki, we arrive to
the ancient Tegoi, told in an episode of
the Kojiki, one of the oldest texts of Japan :
Takemidauchi-no-kami throws Takeminakata-no-kami grabbing
his hand with ease, like it was a cane. This Tegoi would be
the origin of Sumo and was transmitted both
in the legend "Nomi-no-Sukune" and "Taima-no-Kehaya" told in
the Nihonshoki and in Sumai-no-Sechie at the court Heian age
and in the samurai Sumo of the Kamaura age. The
Sumai-no-Sechie was a fight in front of the Emperor is here
wrestles from the whole country come together. However, this
was different from modern-day. There was no ring and it was
more oriented to the samurai arts coming from Tegoi. You can
understand it also from the Imperial Edict of Emperor
Jinmei: the Sumai-no-Sechie is not a simple sport, it also
includes methods to improve one's strength. A the times of
Emperor Seiwa, in 868, the Sumai-no-Sechie
that depended by the lead of Shiki-bu Minister was
transferred under that of Hyo-bu Minister and was more and
more characterized by the samurai arts. So the method to
protect the Emperor by the use of Tegoi was trasmitted to
the Seiwa-genji Clan that has its
beginning from his nephew of Emperor Seiwa, Tsunemoto, from
whose teachings it was give to Minamoto Mitsunaka, then
Yoriyoshi, and lastly Yoshimitsu. [...]
BIRTH OF TAKEDA CLAN
[...] Youshimitsu chose the second-born Yoshikiyo
as successor, and gave him the Minamoto banner together with
the family armor. At Nobuyoshi's times the grandson of
Yoshikyo took the Takeda name, since he
lived in the Takeda village of district of Kyoma in Kai.
This is the beginning of the Kai-Takeda family from which
later on Takeda Shingen was born. In the
Takeda family Daito-ryu was handed down the banner with the
armor of the Minamoto. [...]

THE NAME
[...] The name "Daito-ryu" comes from Shinra
Saburo Minamoto Yoshimitsu who was the founder of the school
nine hundred years ago. When he was a child, he lived in the
Daito castle in Åmi province and so he was called SaburÅ
Daito, from whom the school take its name. However, until
TaishÅ era (from July 30, 1912 to December 25, 1926) [the
school] was called "Yamato-ryu" (大流), even though it was
written with the same kanji as "Daito-ryu". [...]
