Prepare the ingredients by slicing the daikon radish, gobo, and mushrooms into bite-sized pieces. Cut the tofu into small cubes and slice the aburaage into thin strips.

In a pot, bring the dashi to a gentle simmer. Add the daikon radish, gobo, mushrooms, tofu, and aburaage. Cook until the vegetables are tender.

Add the natto to the pot and simmer for a few minutes. This will mellow out its strong smell and stickiness.

Serve hot and enjoy this comforting and nutritious soup!
