Key risk: Plain onigiri with pickled plum (umeboshi) filling is one of the safer Japanese convenience foods, but the variety matters. Tuna mayo filling contains mayonnaise (egg and soy). Some rice is flavored with soy sauce and dashi. Konbini (convenience store) onigiri often list allergens, making them more transparent than restaurant versions.
