Makisu Bamboo Rolling Mat and Maki Technique

Developed alongside sushi culture in Edo period; the bamboo mat's origins possibly connected to tofu-pressing tradition; the inside-out uramaki is a Japanese-American invention attributed to Ichiro Mashita, 1960s Los Angeles

The makisu is a woven bamboo mat (approximately 25×25cm) used primarily for rolling maki-zushi and tamagoyaki, but also for pressing moisture from boiled leafy greens (ohitashi) and shaping cylindrical tofu preparations. For futomaki (thick rolls) and hosomaki (thin rolls), nori is placed shiny-side-down on the mat, rice spread to the near edge leaving a 2cm border at the far end, filling placed 1/3 from the near edge, and the mat is used to roll by lifting the near edge over the filling and pressing to establish the first curve before completing the roll. The final quarter-turn press shapes and firms the cylinder. Uramaki (inside-out rolls) reverse the rice-outside-nori-inside geometry, requiring rice applied directly to the mat (covered with plastic wrap to prevent sticking) with nori on top. A firmer makisu (tighter weave) produces firmer rolls; a looser weave allows more moisture to escape during reshaping boiled greens.

The rolling pressure affects final texture — light rolling creates an airy roll with distinct rice grains; tight rolling creates dense compact cross-section; neither is superior, each suits different eating contexts
