In a saucepan, add quail eggs and enough water to cover them. Bring to a boil, then reduce the heat and simmer for 3 minutes. Turn off the heat, drain the water, and immediately transfer the eggs to a bowl of cold water. Let them soak for 10 minutes, or until completely cooled.
Meanwhile, prepare the marinade by combining soy sauce, water, sugar, garlic, green onion, and chili pepper in a mason jar. Stir well and set aside.
Once the quail eggs are cold, peel them carefully and place them in the marinade jar. Cover the jar and refrigerate overnight or for up to 24 hours.
When serving, transfer the quail eggs to a small plate and drizzle with the marinade sauce, if desired.
