Suzume is possibly the most popular ramen shop in Hiroshima. The ramen is excellent, but as the shop owner proclaims: "They only come to see the Kobukuro signature." I doubt that. Suzume also has ties to Shimai, but I'm not exactly sure where they intersect. The soup consists of a rich tonkotsu and chicken base with a good amount of shoyu. I like it and I'm sure you will too.
From Hiroshima Station take the #2 Hiroden Streetcar to Koami-cho. Walk over the bridge and make a left on the first street heading South. After a few blocks you'll see Suzume on your right. Open from 3pm to 9pm. Closed on Sundays and every 14th of the month.
