Koukaibou Monzen-Nakacho: A Ramen Poem in the Downtown Atmosphere
When it comes to Tokyo’s downtown, Monzen-Nakacho is definitely a place where you can feel a deep sense of human warmth. Here, there are the Fukagawa Fudo-do Temple, the Tomioka Hachimangu Shrine, and culinary treasures hidden in the alleys. The “Koukaibou” introduced today is like a warm pearl in this neighborhood, soothing every passing soul with bowls of meticulously simmered ramen.
Small shop, big love, an embrace of dried sardine aroma
“Koukaibou” is located about 6 minutes on foot from Exit 6 of Monzen-Nakacho Station. Walking a short distance along Kasai-bashi Street, you can see its low-key yet friendly storefront. Pushing open the door, you are greeted by the rich aroma of dried sardines, like a warm embrace that instantly lets you put down your fatigue. The shop space is not large, mainly consisting of L-shaped counter seats plus a few small tables, totaling over ten seats, yet it is always packed with people. From noon to evening, there is often a long line at the door; students, office workers, and even ramen fans who have traveled from afar are all attracted by this aroma.
The atmosphere here is a bit like an old-school kissaten (coffee shop), yet it carries the casualness of street food. There are no fancy decorations on the walls, but the heat wafting from the kitchen and the kind smiles of the owner couple make the whole space full of the warmth of home. Only two people manage everything in the shop—the owner, Hiroyuki Taguchi, is responsible for cooking, while his wife is responsible for greeting customers; the two cooperate seamlessly. When ordering, the wife will gently remind you that “luggage can be placed on the chair behind you.” This delicate care makes one feel that coming here is not just about eating ramen, but more like being treated to a feast for the soul.
Signature Dish: Ramen, a perfect balance of gentleness and depth
The signature dish of “Koukaibou” is, of course, “Ramen.” This bowl of ramen is not the greasy, intense type, but rather an animal-based broth simmered from pork bones and chicken bones, paired with the seafood flavors of dried sardines and katsuobushi, and then blended with the natural sweetness of vegetables like onions and potatoes to create a unique texture that is both refreshing and rich. When served, the steam still lingers around the edge of the bowl, and the surface of the soup is topped with thick chashu, crunchy bamboo shoots, green onions, and nori—simple yet full of layers.
With the first sip of soup, you will be amazed by its gentle flavor. The roundness of the pork bone and the umami of the dried sardines are intertwined; it is neither so intense that it becomes cloying, nor so light that it loses its presence, balancing perfectly at a level where you could drink it every day. The owner once said that what he wanted to make was ‘ramen like miso soup,’ and this philosophy is perfectly embodied in the broth. The noodles are medium-thick egg noodles specially made by Marutomi Seimen, slightly elastic, and after soaking up the soup, they slide down the throat so smoothly that you cannot help but take one bite after another. If you add the ‘Ajitsuke Tamago’ (marinated egg), the soft-boiled yolk mixed into the soup makes it even creamier, bringing an explosion of happiness.
In addition to the basic version, there are choices such as ‘Menma Ramen’ (bamboo shoot ramen) and ‘Chashu Gohan Set’ (roast pork rice set). The roast pork uses fresh domestic pork shoulder, which is thick yet melts in your mouth, carrying a faint meaty aroma and winning universal acclaim without relying on excessive seasoning. For those who love spicy food, the shop also has a hidden spicy option, but for a first visit, it is recommended to start with the classic version to experience the gentleness unique to ‘Koukaibou’.
A 15-year journey from passion to a renowned shop
‘Koukaibou’ was founded by Hiroyuki Taguchi in 2001-10. It is said that Taguchi was originally an ordinary office worker who decided to quit his job to open a shop because of his near-fanatical love for ramen. He did not pursue the kind of exaggerated flavor that surprises you at first bite, but rather a daily taste that you would want to eat every day. After countless trials, he finally found this perfect formula with dried sardines as the core and an animal-based broth as a supplement. The shop name ‘Koukaibou’ is a term he created himself, meaning ‘hope to be looked forward to by a wide range of customers,’ and this original intention has become a reality over time.
After opening, ‘Koukaibou’ gradually became a gourmet landmark in Monzen-Nakacho thanks to its authentic ingredients and attentive service. When it reached its 15th anniversary in the year 2016, the outside of the shop was filled with congratulatory flower baskets, showing its influence in the local area. Today, it is not only selected as one of the top one hundred ramen shops but is also hailed by ramen fans as a ‘must-eat in Tokyo.’ Despite its growing fame, the owner and his wife have always remained low-key, focusing on every bowl of ramen in front of them every day; this persistence is moving.
Queuing is the norm, especially during peak dining hours when waiting times vary depending on the situation, but the turnover rate is not low, so waiting patiently is definitely worth it.
Next time you come to Monzen-Nakacho, don’t forget to push open this door and let ‘Koukaibou’ warm your stomach and heart with a bowl of ramen!
