  2. While the rice is cooking, mix together the vinegar, honey, and salt.
  3. Mix the natto and soy sauce together.
  4. After cooking, allow the rice to sit for 15 minutes. Be sure to discard the kombu after cooking.
  5. In a large, flat glass baking dish, place the rice in it and sprinkle the vinegar mixture over the rice.
  6. Using a flat spatula, mix and turn the rice with a cutting motion.
