Kamui Jubei was born on September 13, 1959 (year 34 of the Showa era) and is a respected figure of classic kinbaku. He describes himself as kugutsu no kinbakushi (傀儡の緊縛師), “the rope puppeteer.”
Kamui’s most recognizable trademark is his abundant and creative use of pulleys (shachi) to build suspensions, a technical mastery he learned and refined from the teachings of master Saikatsu.
His influences bridge the reserved and the classical. On one side, the discreet Matsui Kenji, a master who always worked in the shadows and never allowed his face to be photographed, passed on to him not only ties such as the mitsu-hiki shibari but a whole philosophy of discretion and essence.
On the other, his time at the demanding Bakuyukai (縛友会) dojo under Miura Takumi (神浦匠)—a pioneer in rescuing and systematizing the capture arts of hojojutsu as a martial discipline—gave him a solid technical foundation. There, Kamui completed the four levels of training in just two years, a path that usually took several and that most people abandoned.
In 2008, Kamui gave shape to his most personal project: Mumonbaku (無門縛), whose name means “gateless tie” or “absolutely free.”
What began as an “Introduction to Kinbaku Workshop” in Yokohama took firm root and became a leading rope gathering (nawakai) in the Kanto region.
In 2023, Kamui consolidated his independence by setting up Mumonbaku’s permanent home in its own premises in Iruma.
As the community itself defines it, it is a school specializing in the classic style and in semenawa, forged under the influence of Matsui Kenji and master Miura Takumi, the previous sodai of the Bakuyukai.
It is a space with complete confidence in technique, but without shutting itself up in dogma: visiting other styles and schools is allowed and celebrated, embodying an uncommon freedom to learn and move between schools.
In December 2021 (year 3 of the Reiwa era), Kamui Jubei was named third sodai (總代) of the Bakuyukai, the institution founded by Akechi Denki and Miura Takumi in 1998.
Taking on that leadership meant the definitive fusion of the most rigorous tradition with the creative freedom he has always defended.
Illness and return (2026)
In late April 2026, during a stay in Thailand, Kamui Jubei suffered a sudden health problem that required urgent hospitalization and later medical repatriation to Japan, where he underwent emergency surgery.
After several months of recovery, he was discharged from hospital in September 2026 and resumed his activity.
