Ramen Kokuu
らーめん 穀雨
Overview
“Ramen Kokuu,” established in 2012, is located on the 1st floor of Ishijima Building, 29-5 Sakuragaoka-cho, a 7-minute walk from JR Shibuya Station West Exit. The owner hails from “Shina Soba Kazuya” in Meguro. As a highly regarded restaurant following the lineage of “Tantan-tei” (たんたん亭系譜 Tantan-tei keifu: Tantan-tei lineage/style of ramen, known for its distinctive roast pork), it has long been supported in an area slightly removed from the hustle and bustle of Shibuya. The biggest feature is the perfection of its W soup (double soup), which combines animal-based broths (chicken and pork) with seafood-based broths (dried sardines - 煮干し niboshi, and bonito flakes - 節系 fushi-kei). The soy sauce tare (醤油ダレ shoyu tare: soy sauce base/seasoning) is designed to be low in saltiness and assertiveness, serving as a gentle complement to the soup, achieving a mild and harmonious balance. Signature dishes include Ramen (850 yen), Shio (Salt) Ramen, Tantanmen (坦坦麺 tantanmen: spicy sesame noodles), and various Wonton Men. Among these, the Chashu Wonton Men (1350 yen) is especially popular, encapsulating the shop's charm in a single bowl. The chashu (roast pork) is made from pork shoulder, prepared in the “Tantan-tei” style: roasted hanging after being coated with a honey-infused sauce. The meat is of high quality, carefully roasted to achieve remarkable tenderness in both fat and lean portions. The pricing also offers good value, with an additional 4 slices for approximately 300 yen. The wontons are small but generously filled with a classic, ginger-infused meat filling, with 5 pieces costing approximately 200 yen. The noodles are medium-thin, slightly wavy straight noodles from Daiei Shokuhin. Unusually for this lineage, they employ a “tebo” (テボ tebo: basket strainer) for cooking and draining the noodles. Finally, chopped onions added towards the end provide a pleasant flavor change (味変 ajiken: flavor change/enhancement) reminiscent of niboshi ramen. Despite its location just a 7-minute walk from Shibuya Station, Ramen Kokuu offers a calm and relaxed space for dining. It has long been cherished by repeat customers who seek a subtly flavored bowl of ramen in a tranquil setting.
How to Order
1Before entering
This long-established shop, opened in 2012, is located on the 1st floor of Ishijima Building at 29-5 Sakuragaoka-cho, a 7-minute walk from JR Shibuya Station West Exit. Open Mon-Fri 11:00-15:00 / 18:00-20:00, Sat 11:00-15:00. Closed on 1st, 3rd, 5th Saturdays, Sundays, and public holidays. It's a popular spot with a Tabelog rating of 3.7 or higher, but there are times outside peak hours when you can dine peacefully, such as being 6th in line slightly after 12:05 PM opening, no wait at 2:10 PM, or no previous customers before 3 PM on a Monday.
2Purchasing meal tickets
There is a ticket vending machine near the entrance inside the store. The system is to purchase a ticket first and then proceed to your seat. The vending machine does not have English indications, but it comes with recommended labels, making it relatively easy (difficulty level 2) for first-time visitors to find what they want. Signature items include Ramen for 850 yen, Shio Ramen (Salt Ramen), Tantanmen, Chashu Wonton Ramen for 1350 yen, and Shoyu Wonton Ramen (Soy Sauce Wonton Ramen) for 1000 yen. Various toppings (Wonton + about 200 yen, 4 extra Chashu slices + about 300 yen, Nitamago (seasoned egg)) and rice dishes are also available. Payment is cash only; credit cards, e-money, and QR code payments are not accepted.
3Seating and receiving your order
The compact interior has only 9 counter seats. If there are empty seats, you will be guided sequentially, and you hand your meal ticket to the staff when you sit down. Serving time is quick, around 5 minutes, though you might wait briefly by the wall when the shop is full.
4Other
The owner comes from "Shinajin Soba Kazuya" in Meguro, making this a highly skilled shop that follows the "Tantantei" lineage. The soup is a W soup, combining animal-based broth (chicken, pork, etc.) with seafood-based broth (dried sardines, bonito flakes, etc.). The soy sauce base is subtle in saltiness and prominence, serving as a gentle complement to the soup. The noodles are medium-thin, slightly wavy straight noodles from Daiei Shokuhin, prepared using a "tebo" (strainer basket). The chashu (roast pork) is shoulder meat finished in the "Tantantei" style, brushed with honey-infused sauce and roasted by hanging, achieving a quality comparable to authentic Chinese restaurants. The wontons are small but well-filled with a firm meat filling, offering an authentic ginger-infused flavor. Chopped onions at the end serve as a flavorful change, typical of dried sardine ramen.

鰹節の旨みを主体とし、飲みやすい醤油スープ。ワンタンのクオリティは、野生味あふれる感じでかなり高い。
何より鶏油のべたつかなさは脱帽もの。
