In Japan, many people like to add soy sauce, mustard, green onion or nori (dried seaweed). If you want to go fancy, you can add kimchi, eggs, grated daikon (Japanese radish) or even cooked young sardines. These "add-on" ingredients also vary depending on regions or families, giving Natto a unique charm to everyone who enjoys it. What's your favorite?
