In medium bowl, whisk together eggs, mirin, sugar, a pinch of salt and dashi. In large non-stick skillet over medium heat, heat oil. Pour one-third egg mixture into pan. Once eggs start to set, fold it like an omelet onto itself, turning it to the side of the pan, making room to add another one-third amount of egg mixture. Let that amount set and roll omelet in opposite direction to layer together. Repeat with remaining egg mixture to create one layered rolled omelet. Cut into 8 sections.
