"Buta" is pig or pork in Japanese, in this case, thinly- sliced tender pork and "shoga" is ginger, the main. marinade, along with mirin, sake and shoyu.

Ramen is typically classified by broth flavor, with three especially common categories: shoyu (soy sauce), shio (salt), and miso. A fourth, tonkotsu, references the broth's base ingredient, not flavor.

I tried Japan's rarest ramen flavor. It's called the Ice Ramen, and its ingredients are so insane. that only brave people are able to eat it, because you can only get it at the Ice Ramen restaurant, which is completely made of ice.

The broth for tonkotsu ramen is based on pork bones, and tonkotsu (豚骨/とんこつ) in Japanese means "pork bones". The soup broth is prepared by boiling the bones in water for a significant amount of time, up to eighteen hours, and the broth is typically cloudy in appearance.
