Make the marinade. In a small saucepan over medium-high heat, add the soy sauce, dark soy sauce, dashi broth, mirin, sake, and sugar. Bring to a boil and whisk to combine. Once it is boiling, reduce the heat and simmer for 1 minute. Set aside to cool completely.

Soft boil the eggs. In a medium pot, add enough water to cover the eggs and vinegar. Boil over high heat. Carefully, lower the room temperature eggs onto the bottom of the pot with a spider strainer or a slotted spoon and gently rotate the eggs for the first 2 minutes. Turn the heat to medium heat and simmer for 6 minutes and 30 seconds.

Place the eggs in an ice-water bath. Using a slotted spoon or spider strainer, scoop the eggs out and transfer them to an ice bath. Make sure the ice water covers the eggs. Chill for at least 10 minutes then gently peel the eggs. Pat to dry and set aside.

Marinate the eggs. Add the eggs and cooled marinade into a large ziplock bag or a container with an airtight lid. Marinate in the refrigerator for at least 8 hours or overnight. Rotate the eggs after 4 hours for even coverage.
