Tension (Les Studio Tension Inc.)
A Japanese-styled rope studio whose required Fundamentals class leads into color-coded levels covering floor work, partial suspension and suspension, alongside self-tying, structure-theory and Nawajutsu classes.
Tension presents itself as an alternative-lifestyle wellness center built around a shibari school. It is run full-time by the rope educator and artist Willcat, whose teaching is component-based and modeled on martial-arts training, with a focus on safer practice; the studio’s team pages also feature Masha. Willcat’s profile states that Willcat has no dedicated sensei and is not authorized to teach any particular Japanese rope style, and that the basics taught at Tension blend frictions and concepts from many teachers.
Class path
Every student starts with Fundamentals (beige, level 0), which covers basic safety, common pitfalls, first ties and floor work. FloorPlay (green, level 1) builds harnesses and floor work. Fundamentals of Suspension (yellow) and Partials & Play (red, level 2) introduce uplines, locks, line management and partial suspension, and level 3 (black) covers dynamic suspension and advanced ties in private classes. The studio stresses that the colors are not certifications. Parallel tracks open after Fundamentals: Flying Solo for people learning without a partner; The L.A.B. (Logic, Architecture, Balance) on Thursdays, on structure and suspendable construction; and Nawajutsu, technical rope training in a martial-arts setting that sits within the studio’s own dojo next to other martial-arts classes.
Practice, shows and access
Supervised open practice runs until 10 p.m. on several days a week, and Rope Socials take place on the first Saturday of each month and after alternate Wednesday FloorPlay classes. Soirée Shibari is a monthly performance night with scenes by visiting performers and by the studio’s own level 2 and 3 students, followed by open space. Guest teachers give weekend intensives, private lessons are available, lessons can be bought as video on demand, and memberships bundle classes. Tension has adopted the Kink Educators Code of Conduct and uses accountability circles. Its scholarship and energy-exchange program gives priority to LGBTQ+ (especially trans and nonbinary), BIPOC and economically excluded students, who can contribute time and work in place of some or all of the fees. During Montreal Fetish Weekend 2026 the studio hosted a social night, the free KNOcTAMBULE open performance evening, workshops including a shibari demonstration by Willcat, and a craft fair.
