Uchiwa

A flat, non-folding fan used specifically in sushi preparation to rapidly cool freshly seasoned rice while it's being mixed, which helps it achieve the right glossy texture and stops overcooking from residual heat.

Material & Construction

A flat paddle of woven bamboo or paper stretched over a bamboo frame, with a straight handle, distinct from the folding fans used for personal cooling.

Traditional Uses

Fanning rice briskly by hand while another cook folds in seasoned vinegar, a two-person or rapid solo technique essential to properly textured sushi rice.

Modern Availability / Equivalents

An electric fan directed at the rice bowl, or a folded piece of cardboard, are common informal substitutes outside dedicated sushi-making contexts.

Care & Maintenance

Wipe with a dry cloth; keep away from damp storage, since the paper or bamboo weave can warp or mildew if stored wet.
