Bu no Kiwami is a tonkotsu shoyu iekei ramen shop a two-minute walk from the north exit of Kinshicho Station in Tokyo. It serves a rich pork bone and soy sauce broth with medium-thick straight Sakai Seimen noodles, chicken oil, and grilled green onion. Customers choose noodle firmness, broth richness, and oil amount to their preference, and rice comes with free refills. The interior is small, so a line forms during busy hours.
