Kasuri (缭, from kasuru = to graze, scratch) is the Japanese term for ikat: resist-dyed yarn in which selected sections of warp or weft threads are tightly bound before dyeing so that the dye does not penetrate the bound sections, creating the characteristic blurred-edge pattern when the yarn is woven. Japan developed three major regional kasuri traditions on cotton that are distinct in technique, design vocabulary, and cultural context: Kurume kasuri in Fukuoka Prefecture on Kyûshû (cotton warp ikat with precise geometric patterns, now protected as a GI geographical indication product), Iyo-kasuri in Ehime Prefecture on Shikoku (cotton kasuri known for large-scale pictorial and abstract designs), and Shimane kasuri in Shimane Prefecture on Honshû (cotton ikat with bold indigo designs on white ground). The Japanese kasuri Patreon audience — combining the Japanese diaspora in the United States, Brazil, Canada, and Australia with the global Japanese craft community — runs at 70 to 80 percent iOS concentration, making kasuri creators significantly exposed to the Apple Tax beginning November 2026.

Kasuri technique: kukuri binding and dye resistance

The kasuri process begins before weaving: yarn is wound onto a measuring frame to count the required length, then specific sections of the measured yarn are tightly bound with resist material (traditionally cotton string, now often rubber bands or plastic tape in contemporary practice) to prevent dye penetration at those points. The binding must be tight enough to compress the fiber bundle to the point where the dye bath cannot penetrate the interior fibers, while the unbound sections absorb full dye saturation. The bound yarn is then dip-dyed in an indigo fermentation vat (sukumo vat: composted indigo leaves from Tokushima Prefecture, or the natural fermentation of fresh indigo in alkaline ash lye) for the characteristic indigo blue-on-white kasuri color pattern. Multiple dip-and-air-oxidation cycles deepen the indigo to the desired value. After dyeing and drying, the bindings are removed to reveal the resist-protected (undyed) sections. The warp or weft threads are then arranged on the loom with precise alignment of the undyed resist sections to produce the pattern when interlaced. The challenge of kasuri is the alignment precision: the resist-dyed pattern sections must align from thread to thread across the warp width (for warp kasuri), or from pick to pick across the weft width (for weft kasuri), and misalignment produces the characteristic blurred kasuri edge that is simultaneously the tradition’s visual signature and its quality challenge.

Tate-gasuri (warp kasuri) resists the warp threads; yoko-gasuri (weft kasuri) resists the weft threads; tate-yoko-gasuri (combined kasuri) resists both and is the most technically demanding, producing patterns that emerge only when both axis alignment conditions are simultaneously met during weaving. Kurume kasuri specializes in tate-gasuri and tate-yoko-gasuri at high warp-thread counts, producing geometric patterns with very fine definition. Contemporary Kurume kasuri producers work with Jacquard-aided kasuri winding machines that can bind hundreds of warp threads in coordinated pattern positions, but traditional hand-binding (te-kukuri) continues among specialist practitioners and is the primary Patreon content draw: the documentation of each binding step, each dye bath, each alignment check during warping, and each weaving correction reveals a process that is invisible in the finished cloth.

Japanese diaspora and the Apple Tax

The Japanese diaspora Patreon audience for textile and craft content is concentrated in California (San Francisco Bay Area, Los Angeles, San Diego), Hawaii, Washington State, and British Columbia in Canada, with the largest non-USA Japanese diaspora in Brazil (São Paulo) and Australia (Sydney, Melbourne). iPhone adoption in the Japanese-American demographic runs approximately 70 to 80 percent, consistent with Japan’s national iPhone adoption rate of approximately 65 to 75 percent and the higher rate among the tech-engaged urban diaspora segment. At $200 per month with 73 percent iOS concentration, Apple’s 30 percent commission from November 2026 is $43.80/month ($525.60/year). At $350 per month with 75 percent iOS, the commission is $78.75/month ($945/year). At $500 per month with 77 percent iOS, the commission is $115.50/month ($1,386/year). Web-only subscription routing via KeepTier eliminates this commission entirely at $9/month per creator.
