Step 1

Add the water and the kombu to a stock pot and let it steep for 30 minutes.

Step 2

Place the stockpot over medium heat and bring it to a boil. Remove the kombu and add the bonito and stir it once to mix in. As soon as the liquid boils again, decrease the heat to low and simmer for 5 minutes. Remove any scum that appears on the surface.

Step 3

Turn off the heat and let the liquid steep for 15 minutes. Strain it through a fine sieve or cheesecloth. Don't squeeze the bonito flakes because it would make the dashi cloudy. Discard the bonito flakes after use.

Step 4

Prepare the broth by combining the dashi, mirin, and soy sauce. Set aside.

Step 5

Place the cabbage on the bottom of the nabe pot. On top of the cabbage, add the harusame, tofu, clams, shrimp, scallops, red snapper, chicken, negi, spinach, mushrooms, and carrot, arranging each ingredient in a neat order. Pour the broth over, cover the hot pot and bring it to boil over high heat until cooked.

Step 6

Transfer the hot pot to the dining table and serve immediately.
