Ramen Kurouzu
らぁ麺 くろ渦
Overview
"Ramen Kuro-uzu" (located at Shinjuku 3-7-8) is conveniently situated just a 2-minute walk from Shinjuku-sanchome Station and a 7-minute walk from Shinjuku Station. As a sister restaurant developed by the popular Tokyo ramen group "Hayashida," Kuro-uzu distinguishes itself from Hayashida's dashi (broth) system by offering a "soy sauce-forward" bowl and a unique Nodoguro (blackthroat seaperch) ramen as its signature dishes. Its most distinctive feature is the soup made with duck and Daisen chicken, boasting a rich balance of depth, oiliness, and sweetness. This pairs excellently with the thin, straight noodles, creating a smooth slurp and a pleasant, crisp texture. The signature Shoyu Ramen and Special Shoyu Ramen feature a straightforward composition where a robust soy sauce flavor and the umami of chicken soup come together seamlessly, with the soy sauce taking a more prominent role than in Hayashida's offerings. The other main attraction is the Nodoguro Ramen (1050 yen), which boasts a three-layer structure: clear chicken broth (tori chintan) + blackthroat seaperch dashi + blackthroat seaperch oil. This authentic dish involves grilling the heads and central bones of blackthroat seaperch before adding them to the chicken broth, and finishing with blackthroat seaperch oil extracted at low temperatures from the skin, fat, and bone areas, resulting in a refreshing yet profoundly rich flavor. The noodles have a uniquely smooth texture, made from a blend of wheat and tapioca flour. They are complemented by the crisp sweetness of hoshisaki menma (bamboo shoots) and the rich, orange yolk of a maximum egg. The Mazesoba (soupless ramen) typically features a soy sauce-marinated egg yolk in the center, to be mixed with the chewy noodles. It offers a satisfying experience akin to a full-course meal, even including the finishing "Oimeshi" (rice mixed with the remaining sauce). A distinctive feature is also the option to squeeze lemon midway, which instantly transforms the flavor profile in a refreshing direction. The Tsukemen (dipping noodles) features a rich soy sauce-based soup, with slightly softer noodles that are easy to eat, making it an approachable option for international visitors. This restaurant is ideal for those in the Shinjuku-sanchome area who wish to explore a diverse range of soy sauce-based ramen, Nodoguro ramen, and mazesoba.
How to Order
1Before Entering
Conveniently located at Shinjuku 3-7-8, a 2-minute walk from Shinjuku-sanchome Station (Toei Shinjuku Line, Tokyo Metro Marunouchi Line, Fukutoshin Line), and a 7-minute walk from JR Shinjuku Station Central East Exit / East Exit. Open long hours from Monday to Sunday, 11:00 AM to 11:00 PM. There might be a queue for purchasing meal tickets during weekend lunch hours, but the turnover is quick, and it can be less crowded during off-peak times on Saturday and Sunday afternoons.
2Purchasing Meal Tickets
Purchase meal tickets at the vending machine near the entrance before proceeding to your seat. The ticket vending machine has photos and English guidance, making it moderately easy to use (difficulty level 2). Near the entrance, there's a unique sight of egg cartons and noodle cases stacked chest-high, and the path to the counter can sometimes be narrowed by these cartons, so proceed straight inside without hesitation. Signature dishes include Shoyu Ramen, Special Shoyu Ramen, Tsukemen (dipping noodles) 950 yen, Mazesoba (soupless noodles), Nodoguro Ramen 1050 yen, Nodoguro Ajitama Ramen 1200 yen, plus toppings like 5 extra sheets of nori seaweed, Ajitama (seasoned egg), half kaedama (extra noodle), and full kaedama (extra noodle) 150 yen. If you use a Hayashida Group app coupon, you can get free topping additions. Payment is cash only; credit cards, e-money, and QR code payments are not accepted.
3Seating and Receiving Your Order
The interior is compact, with 11 counter seats and 1 table. If there are empty seats, you will be guided sequentially; hand your meal ticket to a staff member when you take your seat. The noodles are thin and have a short boiling time, so your order will be served quickly, in about 3-5 minutes. Half kaedama (extra noodle) are also served immediately.
4Other Information
As an affiliate of the popular Tokyo restaurant group 'Hayashida,' this shop features 'Shoyu-dachi' (soy sauce forward) ramen, which has a different dashi (broth) profile from Hayashida, and its unique Nodoguro Ramen as signature dishes. The soup, made with duck and Daisen chicken, offers a balanced richness, oiliness, and sweetness, pairing well with the thin straight noodles for a smooth mouthfeel and pleasant bite. Nodoguro Ramen is crafted with a base of 'Chicken Chintan (clear soup) + Nodoguro Dashi (broth) + Nodoguro Oil.' Nodoguro (blackthroat seaperch) heads and bones are roasted before being added to chicken broth, and Nodoguro oil, extracted at low temperature from the skin, fat, and bone areas, is floated on top as a finishing touch, making it an authentic specialty. The noodles, a blend of wheat and tapioca flour, have a unique slippery texture; the crisp sweetness of the hosaki menma (bamboo shoots) and the rich orange yolk of the maximum egg complement the dish. Mazesoba is typically served with a soy-marinated egg yolk in the center, which is mixed with the chewy noodles. It's a satisfying dish, like a course meal, including the final 'Oi-meshi' (rice mixed with the remaining sauce).
