These dishes often feature flavorful toppings like teriyaki chicken, tempura shrimp, or unagi (grilled eel) alongside traditional mozzarella cheese and tomato sauce. One of the most popular varieties is the okonomiyaki pizza, which takes the classic Japanese savory pancake and combines it with pizza ingredients, creating a crispy crust topped with cabbage, pork, and a drizzle of mayo and okonomiyaki sauce.
