Himokawa udon is a traditional local dish from the Kiryu area of Gunma Prefecture. As its name suggests, the noodles are remarkably flat and wide, resembling ribbons or strips of cloth. Their unusual appearance is quite different from that of ordinary Japanese udon.
The width varies considerably, with some varieties measuring more than 10 cm wide. Because of their striking appearance, Himokawa udon has been featured in television programs and magazines and has become one of Kiryu’s best-known local specialties.
However, the appeal of Himokawa udon goes far beyond its appearance. The dish is closely connected to Gunma’s long-established wheat-based food culture and the history of Kiryu, a city that flourished as an important center of the textile industry.
Gunma has a long tradition of preparing foods made with wheat. The prefecture is well suited to wheat cultivation thanks to its abundant sunshine, relatively dry climate, and well-drained soils.
Against this background, a distinctive flour-based food culture developed, and wheat-flour dishes such as udon became an everyday part of local cuisine.
Himokawa udon is also made from simple ingredients, primarily wheat flour, water, and salt. The dough is rolled out into a large, thin sheet and then cut into wide strips, creating its characteristic shape rather than the round noodles commonly associated with udon.
There are several theories about the origin of the name “Himokawa.” One well-known theory suggests that it evolved from “Imokawa udon,” an old type of flat noodle that is sometimes regarded as one of the predecessors of kishimen noodles.
Another theory connects Himokawa udon with the wide noodles traditionally used in Okkirikomi, another representative local dish of Gunma. Whatever its precise origins, Himokawa udon has become firmly established as part of the region’s food culture over many generations.
Kiryu is known as a historic textile-producing city with a history spanning more than 1,300 years. As the textile industry developed from the Meiji period through the early Showa period, many craftsmen and factory workers worked long and demanding hours in the city.
Udon was a practical everyday food because it could be prepared relatively quickly and was easy to make in larger quantities. Himokawa udon is also thought to have become part of local eating habits as the city’s industries and communities developed together.
The most distinctive feature of Himokawa udon is undoubtedly its wide, thin noodles. Depending on the restaurant and style, the noodles can range from approximately 5 mm wide to more than 10 cm, with some exceptionally wide varieties reaching 15 cm or more.
Despite their impressive width, the noodles are extremely thin, generally around 1 mm thick. This allows them to cook relatively quickly and gives them a smooth, slippery texture and a light, pleasant mouthfeel.
Compared with conventional udon, Himokawa noodles generally have less of the firm chewiness associated with thick udon noodles. Instead, their soft and delicate texture is part of their appeal. The broad surface also allows diners to appreciate the subtle flavor of the wheat itself.
Although the ingredients are simple, making consistently wide and thin Himokawa noodles requires considerable skill.
When the dough is rolled out into a large, thin sheet, it can easily tear or fold during the process. Careful handling and experience are therefore essential. Because the dish is so simple, the technique and craftsmanship of the noodle maker can have a noticeable effect on the final texture and appearance.
Himokawa udon can be enjoyed in a variety of ways. It is often served chilled as zaru udon, allowing diners to enjoy its refreshing texture, but it can also be served hot in a flavorful kake udon broth.
When dipped into a savory sauce, the broad noodles offer a uniquely smooth texture while allowing the flavor of the wheat to come through. Another local-style preparation involves simmering the noodles with vegetables in a soy sauce-based broth, allowing the flavorful soup to cling to the wide surface of the noodles.
From autumn through winter, warm Himokawa udon is particularly comforting and is enjoyed as a hearty dish that helps warm the body during the colder months.
In recent years, extra-wide Himokawa noodles measuring more than 10 cm across have attracted considerable attention. Some are so wide that they extend dramatically beyond the edges of the serving bowl, creating an unforgettable visual experience.
Lifting a single enormous sheet of noodle with chopsticks and enjoying it is a very different experience from eating ordinary udon. For visitors to Kiryu, trying these spectacularly wide noodles can become one of the memorable highlights of a trip.
Himokawa udon is more than just a regional specialty. It is a food tradition that reflects the history, environment, and everyday lives of the people of Kiryu.
The natural conditions that supported wheat cultivation in Gunma, the region’s abundant water and dry climate, and the development of Kiryu as a textile-producing city all form part of the story behind this distinctive noodle tradition. The combination of the local environment and the ingenuity of its people has allowed these unusually wide noodles to be passed down through generations.
When visiting Kiryu, be sure to try Himokawa udon. Experiencing its spectacular appearance and unique texture is only part of the attraction; learning about the history of Kiryu and Gunma’s traditional wheat-based food culture can make the experience even more rewarding.
