Ippudo specializes in Hakata (Kyushu-style) tonkotsu (pork bone soup) ramen. The original flavor of tonkotsu ramen or Ippudo’s original version, shiromaru (white) moto-aji (original flavor), is served in a rich white broth with scallions, roast pork, cabbage and seaweed. They have two other types of ramen: akamaru (red) shin-aji (new flavor) that is even richer with a heavier umami flavor, and karakamen, which is spicy.
