To make the soup, combine water, sake, soy sauce, and chicken bouillon powder in a pot and bring to a boil.
Once the pot boils, lower the heat and season with salt and pepper. Whisk in the potato starch slurry to thicken the broth.
Beat the eggs in a separate bowl. Mix in 2 pieces shredded imitation crab and grated ginger.
Boil plenty of water in a pot, and follow package instructions to cook the noodles. Once the noodles are cooked, drain well and place in a bowl.
Heat oil in a small pan over high heat. Pour in the mixture from Step 3, stir well while keeping the omelet in shape.
Once the omelet is cooked, place the omelet over the noodles from Step 4. Pour the soup from Step 2 and top with green peas. You are done!
