Chukasoba Rukawa
中華そば 流川
Overview
Chuka Soba Rukawa (中華そば 流川) is tucked away in an alley, just a 1-minute walk from Shinjuku West Exit Station and about a 10-minute walk from JR Shinjuku Station. The shop's name is inspired by "Slam Dunk," chosen by the owner, a passionate fan of the series. This unique heritage extends to its sister shops: "Sendoh" in Nakano and "Fujimaya" in Inadazutsumi, all named after characters or schools from "Slam Dunk." The main feature is its soup, branded "Gyukai Chintan" (牛貝清湯/gyukai chintan - beef and shellfish clear broth), a clear soup (清湯系/chintan-kei - clear broth style) crafted from domestic beef bones, chicken, and shellfish dashi (出汁/dashi - broth). It boasts a clear appearance devoid of impurities, where the elegant umami of shellfish layers with the profound richness of beef bones. The animal aroma is kept subtle, allowing the shellfish flavor to lead, while the depth of beef lingers distinctively at the finish, creating a unique balance. This composition, with its restrained animal aroma (often prominent in other beef bone ramen), makes it an approachable option for a wide range of customers, even those new to beef bone ramen. Beyond the signature Gyukai Chintan Shoyu Chuka Soba (牛貝清湯醤油中華そば - beef and shellfish clear broth soy sauce ramen) for 950 yen, the menu is extensive. It includes Shio Soba (塩そば/shio soba - salt-based ramen) served with truffle paste, Gyudashi Mazesoba (牛出汁まぜそば/gyudashi mazesoba - mixed noodles with beef broth), Tokusei Ebi Shoyu Tsukemen (特製海老醤油つけ麺/tokusei ebi shoyu tsukemen - special shrimp soy dipping noodles), and Ebi Miso Tsukemen (海老味噌つけ麺/ebi miso tsukemen - shrimp miso dipping noodles). For those seeking shrimp tsukemen (つけ麺/tsukemen - dipping noodles) in Shinjuku, Rukawa stands as a compelling choice alongside the nearby "Ichigen." The noodles are thin and straight, made by Kanno Seimenjo, known for their pleasant bite and excellent ability to carry the soup. Chashu (チャーシュー/chashu - braised pork or chicken slices) comes in two types – pork and chicken – both cooked at low temperatures and meticulously prepared. The Aedama (和え玉/aedama - seasoned extra noodle ball), priced at 200 yen, is topped with diced chashu, onions, and a generous amount of fish powder, offering a playful array of eating styles: enjoy it as is, add it to your soup, or savor it like tsukemen. The establishment features a compact design with only 10 counter seats and is operated by the owner alone. For those exploring ramen options in Shinjuku West Exit and seeking a unique path different from the conventional seafood-based or Tonkotsu (豚骨/tonkotsu - pork bone broth) styles, this shop is a recommended destination.
How to Order

Open Mon-Sun from around 11:00 (specific closing days/hours to be confirmed at the store). You might enter without a wait if you go slightly off peak, like around 12:30 on weekdays or 13:00 on Saturdays, but during Golden Week or peak lunch hours, there might be a queue of about 3 people outside.
2Purchase Meal Tickets
Buy meal tickets at the ticket machine near the entrance before proceeding to your seat. Signature items include Gyu-Kai Chintan Shoyu Chukasoba 950 yen, Gyu-Kai Chintan Shio Soba 950 yen (with truffle paste for salt), Gyu Dashi Mazesoba 950 yen (Special 1250 yen, omori (large size) +100 yen, can change to whole wheat noodles), Rich Shrimp Shoyu Tsukemen, Rich Shrimp Miso Tsukemen, Aedama 200 yen, kaedama (extra noodle) 100 yen. Sister shops include "Sendo" in Nakano and "Fujimaya" in Inadazutsumi, all named after "Slam Dunk" characters. Payment is cash only; credit cards, e-money, and QR code payments are not accepted.
3Seating and Receiving
With only 10 counter seats and a narrow aisle, if you are guided to a seat at the back, hanging your belongings on wall hooks might make it difficult to move around. Despite being a one-person operation, tissues are provided at the table, and due to the thin noodles, the serving time is short, with your bowl arriving in about 3-5 minutes.
4Other Information
The owner's original "Gyu-Kai Chintan" soup is the biggest characteristic, a clear soup made from a combination of domestic beef bones, chicken, and shellfish dashi. It's crafted to have a multi-layered flavor with the refined umami of shellfish and the richness of beef bones in a clear, pure soup. Animal odor is subtle, with the shellfish flavor prominent and the richness of beef lingering after finishing the soup, creating a unique balance. The noodles are thin straight noodles made by Kanno Seimenjo, with a good bite and excellent soup pick-up. The chashu consists of two types, pork and chicken, both cooked at low temperature. The aedama (flavored extra noodles) comes with diced chashu, onions, and plenty of fish powder, offering multiple ways to enjoy: as is, added to soup, or as a pseudo-tsukemen. The Rich Shrimp Miso/Shoyu Tsukemen is a notable derivative menu item, standing out as a shrimp-based option alongside nearby "Ichigen".

Miso Mendokoro Tasakaya (Ikebukuro): Navigating the Japanese-Only Ticket Machine and a Review of its Robust Miso Ramen
Miso Mendokoro Tasakaya, a miso ramen specialist located in Nishi-Ikebukuro, is just about a 5-minute walk from Ikebukuro Station's West Exit. This shop is known for its hearty miso ramen: a thick, rich, slightly sweet miso broth, firm thick noodles, melt-in-your-mouth chashu, and a towering pile of crisp bean sprouts (moyashi) – a truly robust and voluminous bowl. The menu features four main series: Miso Ramen, Kara-Miso Ramen (spicy miso), Aemen (a brothless mixed noodle dish), and IWGP Geki-Kara Ramen (extra hot). This guide, based on our visit on Friday, May 22, 2026 (arrived at 6:39 PM with a 13-person queue), provides photos and tips for first-time visitors to Japan. We'll cover how to navigate the Japanese-only, no-photo ticket vending machine using a color guide, understand the queuing situation (only 9 counter seats and long noodle cooking times mean slower turnover), tips to avoid crowds, and the cash-only payment policy.

Ramen Jiro "Kabuji" (Shinjuku-Kabukicho): The Complete Guide to Jiro Calls and Timing
Just a 1-minute walk from Seibu-Shinjuku Station North Exit, Ramen Jiro Shinjuku-Kabukicho, affectionately known as Kabuji (a nickname combining Kabukicho + Jiro), is the fourth oldest chokkei (direct-lineage) shop of the Ramen Jiro chain. Its late-night hours from 11:30 AM to 2:30 AM (Mon, Tue, Thu-Sun, closed Wed) are a unique advantage among chokkei shops, making it ideal for combining with Kabukicho sightseeing or as a late-night ramen after drinks. With its semi-emulsified pork-bone shoyu broth, homemade flat thick wavy noodles, unique call (shouted topping order ritual) culture (Ninniku (raw grated garlic), Yasai (boiled bean sprouts on top), Abura (solid back fat for richness), Karame (extra soy tare for stronger salty taste), Mashi (more, about 1.5×), Sukuname (less, about half)), the chokkei system of ticket-folding (a wordless system to request firmer or softer noodles by folding the meal ticket) to specify noodle hardness, lot system (a Jiro-specific eating rhythm where the same batch of customers finish together) manners, and specific rules (no phone calls, no photography except ramen, no drunken entry), this article provides a complete guide based on our visit on May 15, 2026, where we ordered a Small Ramen (¥950) with the call 'Ninniku Sukuname, Yasai, Abura'.
