For example, gyudon (rice covered with beef and vegetables) and nikujaga (simmered meat and potatoes) are considered nihon-ryori, because seasoning specific to Japan, such as soy sauce, soup stock, and mirin (sweet cooking rice wine), is used to give them flavor.
例えば牛丼や肉じゃがは、味付けに醤油や出汁、みりんなど日本特有の調味料を用いるから、日本料理であると考えられる。
