At the age of sixteen Takaki Umanosuke (1656–1746) was awarded gokui (deepest level of the art) by Takagi Oriuemon, the founder of the jūjutsu-style Takaki-ryū Taijutsu. Later Umanosuke learned the jūjutsu-style of Takenouchi-ryū Koshi-no-mawari (i.e. Kogusoku = armoured grappling). From what he learned he called his own style of jūjutsu by the name of Takaki-ryū Taijutsu Koshi-no-mawari.
He devised a number of weapons such as the Rensa Sankakubō, a three-parted Bō connected by chains, which is basically the same design as found in the Sansetsukon of Okinawa and China.
Here are three examples of Kata (=applications) of the style.
