Home of five originals

ICHIRAN started and grew in Hakata, the capital of tonkotsu ramen.
There are five revolutionary "originals" that are said to be "created by ICHIRAN" in the world of tonkotsu ramen.

Hiden no Tare (Spicy Red Sauce)

"Original Spicy Red Sauce" is an ICHIRAN original. Domestically and overseas, ramen is often made with red sauce floating in the middle of the bowl, but this originated at ICHIRAN. We mix 30 kinds of ingredients with our own blended peppers as a base, and we age it for many days and nights. This does not just produce spiciness, but it makes it so that a variety of flavors will unfold in your mouth, giving the ramen an even richer taste. Giving the center of the ramen a beautiful finish, "Original Spicy Red Sauce" is laid on top to look like a circle against the background of the soup.​ ​
The "Original Spicy Red Sauce" is manufactured at the "ICHIRAN no Mori" in Itoshima City, Fukuoka prefecture, and it is shipped from there to all of our domestic and overseas stores. In order to protect the taste, only four people in the company know the ingredients and recipe for the "Original Spicy Red Sauce".​ ​

An aromatic tonkotsu soup

ICHIRAN's tonkotsu soup is a natural tonkotsu soup extracted from 100% pig bones. Simply extracting broth by boiling pig bones will result in an unpleasant odor. At ICHIRAN, we use a special manufacturing method that requires advanced technology, carefully removing excess harshness over time. By doing so, we can preserve the delicious taste of tonkotsu, and we can produce tonkotsu soup with no foul odors at all.
ICHIRAN is the origin of "tonkotsu soup with no bad odors." Temperature management and concentration control are thoroughly carried out every hour to protect the taste and quality of soup.
The finished soup is also checked for concentration, taste, scent, and more by the seasoned palates of our chefs and numerical values ​​from tools, such as densitometers. In the unlikely event that any one of the variables is outside of specifications, we restart from the beginning. Ultimately, we aim to make each bowl of soup completely uniform. Since it is a natural tonkotsu soup that has undergone quality control with so many management systems, when cooking in the store, we strictly adhere to adding the noodles within 30 seconds after pouring the soup in the bowl, thus maintaining the quality of the soup and noodles.

Flavor Concentration Booths


[Japan Patent #4267981]

Our Flavor Concentration System is very pleasing to many customers, and a distinct characteristic of ICHIRAN is our overwhelming number of female customers. Our system attracts numerous famous people and celebrities who come to eat ramen without having to worry about their surroundings.

After all, it takes about 10 minutes to eat ramen in silence. Our Flavor Concentration System creates an environment where you can concentrate just on instinctually enjoying your food in a relaxed state without worrying about your surroundings.
People tense and relax via autonomic nerve function. The autonomic nervous system has sympathetic nerves and parasympathetic nerves. Sympathetic nerves work predominantly during moments of nervousness. The state of tension—such as when playing in a game, entertaining guests, or attending matchmaking meetings—is also, so to speak, a "battle mode" and a "consumption mode," and no one can enjoy a delicious dish in such a situation. The parasympathetic nerves that dominate when relaxing produce a "relaxation mode" and an "absorption mode," and you can purely enjoy the flavors of whatever you eat.
Since you will not be bothered by your surroundings when seated in ICHIRAN's flavor-concentration system, you will enter "parasympathetic nerve mode," which will relax you from the bustle of the city and the strained "sympathetic nerve mode" you experience at work, thus enabling you to enjoy the taste even more.


The Flavor Concentration Booths was born with hints from the various experiences of our representative, Yoshitomi.
When Yoshitomi was a sophomore in college, his father's fight with cancer began, and so he had to earn his tuition and living expenses by himself. Thus, he started part-time at a certain casual restaurant. The manager of the shop was among the best of the best, but he liked to constantly gamble. The shop layout was such that the kitchen was very hard to see from the seating area, but this was a good thing because the manager would very often go out gambling and never come back. As a result, Yoshitomi, who had been involved in the opening of the shop, came to operate the shop by himself, and he was able to polish his cooking skills there.
One day, a regular customer ordered ramen, and, when going home, said, "It was delicious." The same customer visited the store the next day and noticed that Yoshitomi was operating the shop by myself without the manager. The customer ordered ramen and, when finished eating, said, "Your flavors need more work."
The next day, the same customer visited. Since the customer ordered ramen, Yoshitomo said, "The manager made it," and the customer replied, "The manager's ramen is delicious, isn't it?"
All of the ramen over the three days was made by Yoshitomi, but the how the customer felt about the taste was different. At that time, Yoshitomi realized that "the way people feel about the taste depends on who made it."
Yoshitomi himself stood on the street to open ICHIRAN's first store, the Nanokawa store, and conducted a questionnaire. The survey results showed that many women felt that it was hard to enter ramen shops alone. At that time, Yoshitomi remembered that the female students ate their lunches while hiding their mouths when he was a junior high school student. Many women may feel uncomfortable eating when they feel that people nearby are watching them.
そうした経験から、吉冨は「作り手の雰囲気を一切排除し、お客様に一杯のラーメンのみと向き合い、周りを一切気にせず召し上がっていただける環境」を考案。那の川店では、目の前に客席と厨房をさえぎる暖簾を設置いたしました。それが味集中システムのはじまりでした。 その後、博多店がオープンする際に、初めて隣席を仕切る「仕切り板」が導入され、徐々に進化し現在の形となっていきました。  

Written Ordering System

By simply circling your specific preferences on your ramen order sheet- from flavor strength to noodle texture, ICHIRAN makes it easy for you to craft your own perfect bowl of Tonkotsu Ramen.

*English, Korean, and Chinese forms are also available.



Since the menu specializes in ramen, we found out that customers' preferences can be largely divided on the basis of the various ingredients. In order to respond to the individual demands of such customers, we began to respond to customers' preferences related to noodles, soup stocks, richness, fried rice, Hiden no Tare, and garlic.
Initially, Yoshitomi surveyed each customer verbally. Many customers who found this interesting went out of their way to participate in these interactions. As the number of customers gradually increased, we continued to search for a more reliable and concise form, and the current order form was born.


When ordering additional servings of noodles, simply place the seconds plate on the button at the end of the table. A charamela sound will play, and a staff member will come pick up the seconds plate. Female customers are especially pleased with this feature, since they can order without having to speak.


Kae-Dama (noodle refill) is part of Japanese Ramen Culture where you refill your soup with fresh noodles. You can choose a different noodle texture from your first order to compare.


ICHIRAN originally came up with the method of ordering by placing the plate on the call button to make a charamela sound play. When first introduced, Yoshitomi made these himself with a soldering iron, so there were times when sparks scattered and people were given mild electric shocks. At the time, digital equipment was undeveloped, so it was very popular and attracted attention since it was not necessary to speak when ordering. It is now a symbol of ICHIRAN.
