When making tonkotsu ramen, you need to remember that the main ingredient is the broth. The broth is made by simmering pork bones. The broth is thick and viscous, and has a unique flavor that is unique to tonkotsu. Because of the high level of fat and pork, tonkotsu ramen is extremely filling. If you are not a fan of pork, you can also choose to add steamed chicken.
