Romen is a distinctive local noodle dish from the Ina region of Nagano Prefecture. It is made by stir-frying mutton and vegetables with thick, steamed Chinese-style noodles.
There are two main styles of Romen. One is prepared with a Chinese-style broth, while the other is closer to sauce-flavored yakisoba, or Japanese stir-fried noodles, with little or no soup. Both styles have a distinctive character that is quite different from either ramen or yakisoba.
Romen has become one of Ina City’s signature local dishes, and its unusual combination of noodles, mutton, vegetables, and seasonings has earned it a reputation as a flavor that visitors remember long after their meal.
Romen is made with medium-thick Chinese-style noodles produced from wheat flour, kansui, an alkaline mineral water traditionally used in Japanese noodle making, and vitamin B2 as a coloring ingredient.
A particularly well-known variety is the steamed noodle produced by Hattori Seimenjo, a long-established noodle maker in Ina City. These noodles are slightly darker in color than the steamed noodles commonly used for yakisoba elsewhere in Japan.
The noodles have a firm, springy texture that gives Romen much of its characteristic bite. This distinctive steamed noodle is one of the key elements that sets Romen apart from other Japanese noodle dishes.
Mutton is traditionally the main meat used in Romen, accompanied by ingredients such as cabbage and wood ear mushrooms.
Because some people find the characteristic aroma of mutton strong, some restaurants use pork or beef instead. These variations are known as Ton Romen when pork is used and Gyū Romen when beef is used.
Each restaurant has its own recipe, using different combinations of broth, Worcestershire-style sauce, and other seasonings. Garlic is also commonly added before the ingredients are stir-fried together once again, creating a rich and savory flavor.
Romen comes in surprisingly diverse forms. Some versions contain enough broth to resemble ramen, while others have very little liquid and are closer to yakisoba.
There are also creative variations such as curry-flavored Romen and chilled Romen. Since each restaurant has its own approach to seasoning and preparation, two dishes bearing the same name can taste remarkably different.
This diversity is part of the fun of exploring Romen in Ina. Visitors can try several restaurants and discover how each establishment gives the dish its own personality.
Another distinctive feature of Romen is the way it is eaten. Ichimi or shichimi chili pepper is commonly provided as a condiment, but diners are encouraged to adjust the flavor according to their preferences.
Depending on the restaurant, diners may add sauce, vinegar, sesame oil, chili oil, or grated garlic. By combining these seasonings in different ways, each person can create a customized version of Romen.
This freedom to adjust the dish at the table is one of the reasons Romen has remained so popular among local residents.
Romen was created in 1955 at the Chinese restaurant Banri in Ina City. The dish was developed by the restaurant’s owner, Waichi Ito.
At the time, refrigeration equipment was not yet widely available, making it difficult to store fresh noodles for long periods. Ito discovered that steaming the noodles could extend their shelf life.
He then used these steamed noodles to create a new dish, which eventually developed into the Romen enjoyed today.
The ingredients used in early Romen also reflected the resources available in the Ina region at the time.
Mutton was relatively easy to obtain because sheep were raised locally for wool production. The meat became a useful food resource after the animals were no longer needed for their wool.
Cabbage was another natural choice because it was widely cultivated in the region. Combining mutton, cabbage, and locally available ingredients with the newly developed steamed noodles resulted in a dish closely connected to the food culture of Ina.
The dish was originally served under the name “Chā Rōmen,” written as 炒肉麺, meaning roughly “stir-fried meat noodles.” Over time, the name was shortened in everyday speech to simply Romen.
In an effort to promote the local community, Ito allowed other restaurants to freely use the name. As a result, Romen spread throughout Ina City and became a widely recognized local specialty.
Today, Romen is found not only in restaurants but also in local homes and school cafeterias, showing how deeply the dish has become embedded in the everyday food culture of Ina.
Romen has also played an important role in promoting Ina as a food destination.
In 1994, Ina City adopted Romen as part of its local community revitalization efforts, leading to the establishment of the Romen Committee, now known as the Romen’s Club.
In 2004, a monument commemorating the birthplace of Romen was erected near the original Banri restaurant.
June 4 is also celebrated as “Mushi Day,” based on a Japanese wordplay involving mushi, meaning “steam.” On this day, participating restaurants offer Romen at special prices, giving visitors another opportunity to experience this local specialty.
Romen has also participated in nationwide food events such as the B-1 Grand Prix, a competition and festival showcasing local Japanese specialties. Through these events, Romen has helped introduce the name of Ina City to people throughout Japan.
Local groups such as the Ina Romen’s Club and Ina Romen ZUKU Love continue to promote the dish and preserve its culinary traditions.
Romen is not limited to restaurants. Supermarkets and souvenir shops in Ina City sell home-cooking sets containing Romen noodles, seasonings, and mutton, allowing visitors to recreate the local specialty after returning home.
Products associated with long-established restaurants such as Banri and Chatlet can also be enjoyed at home. Some people simply purchase the steamed noodles made by Hattori Seimenjo and prepare their own version using their favorite ingredients.
Another creative product is Romen-man, a steamed bun filled with the ingredients of dry-style Romen. It offers a different way to enjoy the distinctive flavors of this local dish.
Romen is a unique regional dish that grew out of postwar ingenuity and the ingredients available in the Ina region. Its distinctive steamed noodles, mutton, vegetables, and flavorful seasonings have created a style of Japanese noodle cuisine unlike either ramen or yakisoba.
Its greatest appeal lies not only in its unusual flavor but also in the freedom to customize it. Each restaurant has its own recipe, and diners can further adjust the taste with spices, sauces, vinegar, sesame oil, chili oil, or garlic.
At the same time, Romen’s history reflects the creativity of local people and their efforts to make the most of regional ingredients and resources.
When visiting Ina City, be sure to try authentic Romen at a local restaurant. Exploring the different styles and seasonings is a delicious way to experience the history, creativity, and everyday food culture of the Ina Valley.
