The Full Answer

Traditional sashimi (plain raw fish) and sushi rice (seasoned with rice vinegar, sugar, and salt) are naturally gluten-free.

However, eating sushi at a restaurant is a minefield for celiacs. The biggest danger is Soy Sauce, which is 40-60% wheat. Imitation crab (surimi), used in all California rolls, uses wheat starch as a binder. Eel sauce (unagi) and ponzu sauce are made with soy sauce.

Tempura rolls and anything with "crunch" or "crispy" flakes use wheat flour. Additionally, cross-contamination on cutting boards is rampant. To eat sushi safely, bring your own tamari (GF soy sauce), order plain fish/veg rolls, avoid imitation crab, and ask the chef to use a clean cutting board and knife.
