Passionate and Adaptable

William or Willcat
is an experienced shibari practitioner and educator, known for their high intensity & risk, yet precise movement based approach to rope bondage with an artistic flair. Drawing from their years of technical writing and teaching expertise, their exploration and interest lies in both the technical, and emotional facets of shibari. William’s approach transcends mere technique, with the publication of their book, they aim to leave a legacy in the world of rope by helping others build or find a space that honors traditions, encourages growth, and supports community bonds for generations to come. Their teaching philosophy centers around creating a grounded learning environment where rope enthusiasts worldwide, can explore the many aspects of shibari with confidence. Through structured lessons and clear guidance, at varying degrees of difficulty, they provide a foundation for students to delve into their own personal journeys, inspire others to cultivate both mastery and mindfulness while finding their Dō (their own personal path & rope journeys), always with an emphasis on fun, exploration, and mutual respect.

Formal Disambiguation

Their style is informed by many styles and despite being heavily rooted in some is not recognized or officially "authorized" to teach in any particular style;

Willcat’s approach to teaching shibari is fundamentally component-based, a technical training methodology inspired by martial arts and designed with a focus on safe(r) practices—especially for Western students. This approach balances traditional influences while meeting the needs of a broader audience in a way that prioritizes clarity and structured learning. An argument for the ages, as this goes against the grain of many traditional tendencies, all the while attempting to integrate them.

While running a full-time studio, Willcat continues to hone their mastery of basics, which are a blend of rope concepts and frictions shaped by the teachings of many, including Nawashi Kanna Sama, Pedro Cordas, Midori, EbiMcknotty, Sammy, Nicolas Yoroi, Tifereth, Fred RX, Barkas, Addy, Kindred, Marcos, Nuitdetokyo, Ottonawa San, Tamandua, Ben & the church of fucking around to find out, as well as inspiration from old DVDs, manuscripts, friends, “the internets,” and discoveries from hands-on self exploration.

“I am without a dedicated Sensei, and maybe that is for the best as I can remain unattached to any particular approach and keep doing what I do best, opening doors for others and teaching basics”
