Akechi-ryū 明智流

Akechi-ryū is the lineage that grew out of the rope of Akechi Denki, a Tokyo performer and teacher who was active from about 1978 until his death on July 17, 2005. Its official page traces the lineage back to his ideas and his way of tying, and names as its present holder Akechi Kanna, who took the Akechi name in 2022. The same page pairs the two names, “Akechi-ryū / Kanna-ryū”, for its instructors, studios and community, so the terms overlap rather than describing separate schools.

Akechi Denki’s approach

Akechi learned largely on his own from SM magazines as a young man and developed his style for the stage, where he wanted to show audiences something new each time. In an interview recorded by Osada Steve two weeks before his death, he described rope as communication between two people, said a tie should feel secure rather than harmful, and stressed watching the partner’s face and avoiding nerve injury. He searched libraries and museums for material on rope as a restraining weapon, studied the diagrams he found in a specialist martial-arts book, and reworked those techniques for his own rope instead of reproducing them. His aim, he said, was never to repeat the same tie.

The lineage page credits him with intricate restraints that reach as far as the fingers, functional rope lines and tidy knots. Shibari Dojo goes further and credits him with introducing the gote, hishinawa and kikkō ties to modern practice; that claim is the site’s own and is not made by the lineage page. Shibari Dojo also notes that he co-wrote a book with Miura Takumi in the mid-1990s and adapted his ties to each partner.

Succession

Akechi left no formal deshi, which made the question of succession contested. The lineage page and Nawapedia both date the start of Kanna’s study with him to 2000, and Nawapedia records the two performing together in 2002. Shibari Dojo records a ceremony in Tokyo in 2020 and the formal adoption of the name Akechi Kanna on September 11, 2022, Akechi’s birthday, with the backing of Akechi Kikaku, the company that manages his rights. The Woodshed Orlando event page confirms that Kanna represents Akechi Kikaku. Shibari Dojo adds that the succession was disputed.

The lineage page also lists earlier students of Akechi under the names Raika, Kadera, Enka and Saiki, and a small number of instructors and certified studios abroad authorized by Kanna.

Kanna’s style

Workshop descriptions of the Kanna style, published by Karada House, present it as very restrictive, aimed at full control of the body, and inspired by hojōjutsu. They describe tension taught through diamond (hishi) patterns and the takate kote, careful line management, and semenawa understood as more than pain alone. Nawapedia notes that Kanna wrote “Kanna Style” tutorials for Mania Club magazine in 2003 and has taught many students from outside Japan.
