Cut the tofu and green onion into bite-sized pieces.
Beat the eggs and set aside.
Pour water into a pot and bring it to a boil.
Once the water is boiling, add dried anchovies and kelp to make the broth.
Remove the broth ingredients and add the soft tofu.
Season with soy sauce and salt.
When the soft tofu starts to boil, slowly pour in the beaten eggs while stirring gently.
Add the green onion, let it boil once more, then turn off the heat.
