Ajisen Ramen was founded in Kumamoto, Japan in 1968 and has expanded to more than 700 restaurants worldwide. There is something unique about Ajisen Ramen and it's all in the soup. Our Ramen's Tonkotsu soup can help to prevent aging! The Japanese Society of Nutrition & Food Science announced in a general meeting, "The intake of collagen contained in the bones and cartilage, etc prevents aging." Collagen is a protein, mainly found in the skin, tendon, bone, cartilage and other connective tissues. This protein is the essence of life because it easily makes up one third of the 60 trillion body cells and our Tonkotsu soup has lots of collagen! What is health without taste? A feature of Kumamoto Ramen is Senmiyu; a rich brown sauce that accompanies the fair Tonkotsu soup. Our unique culinary methods ensure that all the flavors are sealed into the sauce. In fact, we guarantee that your taste-buds will be bowled over by our Tonkotsu/Senmiyu combination!
