Overview

Ramen Jiro is a Japanese ramen-shop chain founded by Takumi Yamada in Meguro, Tokyo, in 1968. It developed from a relatively light ramen concept into one of Japan’s most recognizable and imitated ramen styles. The chain is particularly associated with very large servings, thick and dense noodles, a salty shoyu-and-tonkotsu broth, fatty pork, bean sprouts, garlic, and other customer-selected additions. Enthusiasts commonly refer to the style as “Jirolian” or “Jiro-style” ramen. The first shop was established near Tokyo Metropolitan University in Meguro. During Tokyo redevelopment in the early 1970s, it moved to Mita. An accidental change in the Japanese characters used on the shop sign helped establish the name now used by the brand: the characters 二郎 replaced the more conventional 次郎 for the name Jiro. The Mita location subsequently became closely associated with Keio University and developed a strong following among students and other young customers. Ramen Jiro’s appeal is based less on conventional restaurant polish than on abundance, intensity, ritual, and community. Orders are typically made in small or large sizes, with customers responding to staff prompts about additional garlic, vegetables, pork fat, and seasoning. The serving format and ordering etiquette vary in detail by location, but the overall experience is built around a large bowl of inexpensive, highly filling ramen. The brand’s distinctive appearance and flavor have also made individual shops recognizable to dedicated customers. The Mita shop was required to move again in 1995 because of redevelopment. Students petitioned Keio University to accommodate the restaurant on campus, but the university rejected the request. Yamada instead relocated the shop to another site in Mita, where the flagship operation became established. A second location opened in Meguro in the same year, after which the chain expanded steadily through a network of shops across Japan. Reference material counted approximately 40 locations in 2018, with more than 30 in the greater Tokyo area. The chain has generated a devoted customer culture. Fans are known as Jirorians, and some enthusiasts set themselves the challenge of visiting every location. The original or flagship Mita shop is sometimes treated by followers as a pilgrimage destination. This concentrated base of highly engaged customers functions as a form of community-led marketing and has helped sustain the brand without relying primarily on conventional national advertising. Ramen Jiro has also become an internet and technology-culture subject. Daily reviews posted by the Twitter account @habomaijiro attracted more than 35,000 followers before the account stopped updating in 2016 after an unexpected accident. In 2018, data scientist Kenji Doi demonstrated software that could identify the Ramen Jiro location associated with a bowl from a photograph, reportedly distinguishing among about 40 shops with a 94.5 percent success rate in its alpha-stage testing. The project was discussed by technology publications, including Google and The Verge. The portions are central to both the brand’s reputation and criticism. Reference material estimates that a small bowl may contain approximately 1,600 kilocalories, compared with roughly 600 kilocalories for a small bowl at a typical Japanese ramen restaurant, although such figures are estimates rather than standardized product disclosures. Food critics have consequently characterized the food as nutritionally unbalanced or junk food. Despite that criticism, Ramen Jiro remains influential in Japanese ramen culture, and its format has inspired numerous independent restaurants described as Jiro-style establishments.

History

Takumi Yamada founded Ramen Jiro in Meguro, Tokyo, in 1968. The first restaurant was located near Tokyo Metropolitan University and initially served a thinner, lighter ramen than the food for which the chain later became known. Yamada developed a stronger and more distinctive profile with assistance from a neighboring Chinese restaurant. The resulting combination of salty shoyu and tonkotsu soup, dense noodles, fatty pork, and generous toppings became associated with the term “Jirolian style.” Tokyo redevelopment in the early 1970s forced the original restaurant to move from Meguro to Mita. During the relocation, the shop sign used the characters 二郎 rather than 次郎, both of which can be read as Jiro in different contexts. Rather than correcting the sign, Yamada adopted the alternative characters as the brand’s standard written name. The Mita location benefited from its proximity to Keio University and became particularly popular with students. Ramen Jiro’s operating model developed around large, filling bowls and a recognizable ordering routine. Customers generally choose between small and large servings and may be asked whether they want additional garlic, vegetables, pork fat, or seasoning. The exact practices can differ among shops, but the combination of huge portions, thick noodles, rich broth, and customizable toppings became the defining identity of the chain. The approach helped distinguish Ramen Jiro from more conventional ramen restaurants and created a strong following among students, office workers, and dedicated food enthusiasts. In 1995, redevelopment again required the Mita shop to relocate. Students petitioned Keio University to allow the restaurant to move onto university grounds, but the administration declined. Yamada subsequently moved the operation to another Mita site, which became the location associated with the flagship shop. Also in 1995, Ramen Jiro opened a second location in Meguro. The chain then expanded through a network of shops across Japan. Reference material reported approximately 40 locations in 2018, more than 30 of them in the greater Tokyo area. The brand’s growth has been supported by a distinctive customer culture rather than by broad conventional advertising. Devoted fans are called Jirorians, and some attempt to visit all of the chain’s locations. The Mita shop is treated by some followers as a symbolic or “sacred” destination. Japanese economics professor Noriko Arai has described this form of community as a worshipper-style marketing model, in which a relatively small group of highly committed customers generates attention and loyalty. Ramen Jiro has also become a subject of internet culture. The account @habomaijiro built a following of more than 35,000 through regular reviews before stopping its updates in 2016 after an unexpected accident. In 2018, data scientist Kenji Doi used an alpha version of Google AutoML to build software capable of differentiating among Ramen Jiro locations from photographs of ramen. The project reportedly achieved a 94.5 percent success rate during testing and was later discussed by technology-focused outlets. The brand’s size and richness are both central to its attraction and a source of criticism. Reference material estimates that a small serving may contain around 1,600 kilocalories, compared with fewer than 600 kilocalories for a typical small ramen serving, though the figures are estimates and may vary by shop and order. Critics have described the food as high in carbohydrates and fat and low in nutritional balance. Even so, Ramen Jiro has had an enduring influence on Japanese ramen, and numerous independent restaurants have adopted or adapted its large-portion, heavy-broth format under the broader label of Jiro-style ramen.
