This is the flagship dish. The broth uses 70 grams of carefully selected dried sardines per bowl, creating an intensely fishy, umami-forward soup. It's not for the faint of heart—the sardine flavor is the main character, not a supporting player. Reviewers say the broth is unlike any other ramen in Tokyo. Mix of curly and wide noodles that soak up the broth well.
A favorite for those wanting a bolder textural and flavor experience. The dipping broth is an even more concentrated version of the signature stock, offering an intense oceanic punch. It features thicker, more substantial noodles that provide a satisfying chewy contrast to the rich gravy. Reviewers highlight its ability to deliver serious umami without losting the delicate balance of the aromatics.
Tips from diners
This is the 'maximalist' choice. The broth is extremely flavor-dense. Make sure to ask for 'soup-wari' at the end to dilute the leftover broth with hot water—it makes for a perfect savory soup to finish your meal.
Same bold sardine broth as the classic, but this upgrade adds four slices of chashu pork and a large sheet of nori. More protein-forward than the standard bowl. For those who want the sardine broth but with more substance to balance it.
Menma is a classic ramen topping that adds textural contrast. At Nagi, the menma is tangy and a bit spicy, cutting through the heavy sardine broth. It's included with all bowls.
The required side order for hungry regulars. A bowl of high-quality rice is dusted with a potent mixture of ground dried sardines and aromatics. It is designed to be eaten alongside the ramen or added to the leftover broth at the end. Reviewers mention it's the best way to soak up every drop of the savory sardine oil.
The chashu at Nagi is soft and flavorful, a welcome protein addition to the broth-forward bowl. Each slice is thin and tender. Can be ordered as an extra topping.
Tsukemen means dipping noodles. The broth is intentionally made thick and rich—you dip the noodles, don't swim them in soup. The sardine intensity is concentrated. After finishing the noodles, ask for soup-wari (hot water to dilute) to make the remaining broth drinkable. This is a different way to experience the niboshi flavor.
This is the flagship location where Nagi's niboshi ramen was born. Located on the second floor of a small building in Shinjuku's Golden Gai neighborhood. The broth is made from 70 grams of carefully selected dried sardines (niboshi) per bowl, creating a bold, umami-forward flavor. It's not mild—the sardine is front and center. Open 24 hours.
This broth is intense. If you're new to niboshi, start with the standard ramen, not the special. The sardine flavor will hit you hard—that's intentional, not a flaw.
Located on the second floor. Follow the stairs behind the tiny storefront—easy to miss. Often has a line outside even at 2 AM.
This is Golden Gai's most famous ramen spot. It's right in the heart of the neighborhood's tiny bars and clubs. Great stop after drinking with friends.
If you order tsukemen, ask for soup-wari (hot water) at the end to drink the concentrated broth without it being too salty.
