is a school of Japanese swordsmanship (kenjutsu) created by Yamaoka Tetsutaro Takayuki, more commonly known as Yamaoka Tesshà «.
He studied a number of ryu over the years, most notably Jikishinkage Ryu, Hokushin Ittà Â-ryà « and Nakanishi-ha Ittà Â-ryà «. Tesshà « received the full transmissions of both the Hokushin Ittà Â-ryà « and the Nakanishi-ha Ittà Â-ryà « from his teachers. In creating his own line of transmission, he named it the Itto Shoden Muto-ryu to emphasise that he was passing on the correct transmission of Ittà Â-ryà « principles and techniques. The term muto (No-Sword) refers to Yamaoka's stated realisation that the difference between the sword and the self, and between oneself and oneâÂÂs opponent is illusory and that the underlying unity of all is the most important thing in swordsmanship.
The school practice shugyà Â, (austere) training of swordsmanship, which put into test one's mental and physical capacity to the greatest levels. Today, there are very few exponents of YamaokaâÂÂs school. Itto Shoden Muto-ryu is now practiced in Kanazawa, Ishikawa Prefecture. Murakami Yasumasa, who learned from a late Chief Justice of the Supreme Court, Ishida Kazuto, used to be the sixth generation head of the school.
