Ramen Tatsunoya specializes in pork-based, tonkotsu ramen, reflecting our place of origin, Kurume City in Fukuoka, the birthplace of tonkotsu ramen. The broth is simmered for over 15 hours at a high temperature to achieve the maximum umami, providing both a bold richness and a mildness at the same time. Their noodles are using their original recipe which, prior to its use at our Pasadena location, Ramen Tatsunoya’s noodle recipe had never left Japan.
