                                While a single piece of tamago nigiri often contains around 60-70 calories, a larger slice from a full tamagoyaki omelette can easily exceed 100 calories, showing that the exact number can vary significantly. This makes understanding the ingredients and preparation method key to knowing how many calories are in one tamago.
