Japanese omelet

What is Japanese omelet? Is Japanese omelet Japanese cuisine? Japanese omelet is called “Tamago-yaki” in Japanese. Of course, Tamago-yaki is Washoku, Japanese cuisine. We use a specific frying pan for making Tamago-yaki. It is rectangle shaped. The important point of making Tamago-yaki is to stir soy source, sweet sake, sugar and salt into raw egg. The secondary important point is to pour the above mixed raw egg into a frying pan in a few parts. Usually we pour four times. Firstly a quarter of mixed raw egg is poured into a frying pan. When it is baked half, it is rolled and moved to one side on the frying pan. Then a quarter of mixed raw egg is poured into the frying pan again. We repeat the above thing four times.
When Japanese people go to the picnic, Tamago-yaki is almost brought in the lunch box. In this season, the smell of Tamago-yaki is in the air around the park on holiday.
