​​What is Udon? A Review of Its Origins and Characteristics​​

​​​Udon is a type of noodle made from wheat flour. Generally, it is thicker than other types of noodles and has a chewy, elastic texture, making it a staple of Japanese cuisine. Compared to soba or ramen, udon is white and smooth, and the thickness of the noodles varies depending on the shop. It is said that udon was introduced to Japan from China. At that time, there were regions where cultivating white rice was difficult, so udon was chosen as a substitute and became a staple food.

​​​​Udon is a staple of Japanese cuisine, and in some regions, chewy udon is a local specialty. Among the many types of udon, Sanuki Udon from Kagawa, Inaniwa Udon from Akita, and Mizusawa Udon from Gunma are known as the Three Great Udon of Japan.

​​​​Sanuki Udon is characterized by its square shape and chewy texture. It originated in Kagawa Prefecture on the island of Shikoku, and "Sanuki" is the old name for the Kagawa region. The history of Sanuki Udon dates back over a thousand years, and it is said that the Buddhist monk Kukai introduced the method of making udon to Japan and taught it to the people of Sanuki. The climate of Kagawa Prefecture is ideal for growing high-quality wheat, resulting in udon with both elasticity and smoothness. Today, there are over 600 udon specialty shops in Kagawa, and udon has become an essential part of daily life for the people of the prefecture, earning Kagawa the nickname "The Udon Prefecture."​​​

​​​​Akita Prefecture: Inaniwa Udon【One of the Three Great Udon of Japan】​​​

Inaniwa Udon from Akita Prefecture is known for its thinness and is one of Japan’s most renowned udon varieties. Inaniwa is a place name in Akita, and the history of this udon dates back to the 17th century. It is said that a local resident improved the drying process and refined the kneading technique, making it possible to produce thinner noodles. This technique has been passed down through generations, evolving into the unique style of Inaniwa Udon and helping establish its reputation. The dough is kneaded and worked by hand repeatedly, incorporating air into the noodles. This allows them to be stored for long periods and gives them a chewy texture.

​​​​Gunma Prefecture: Mizusawa Udon【One of the Three Great Udon of Japan】​​​

Mizusawa Udon from Gunma Prefecture is characterized by its extremely white color and almost translucent, smooth texture. Its history dates back about 400 years, originally served as a meal for visitors to Mizusawa-dera Temple in Shibukawa City. A dedicated association certifies the quality of Mizusawa Udon, which is made using traditional methods, including a secret two-day kneading process and pure water from Mount Haruna.

Ise City in Mie Prefecture is a small town, but it is a place of great historical significance. Pilgrimages to Ise Jingu Shrine were once extremely popular, and Ise Udon was born from this tradition. To be gentle on the stomachs of pilgrims weary from long journeys, the thick udon noodles are boiled until soft, topped with green onions and bonito flakes, and served with a rich sauce made from dried sardines and soy sauce.

Yamanashi Prefecture: Hōtō

Hōtō, a local specialty of Yamanashi Prefecture

Hōtō is a representative local dish of Yamanashi Prefecture and is considered the soul food of its residents. It features thick, flat noodles made from kneaded wheat flour, simmered with ingredients such as pumpkin, potatoes, mushrooms, seasonal vegetables, and meat in a miso-based broth. Since the noodles are cooked with the flour still coating them, the soup becomes thick and pairs perfectly with the chewy noodles. Historically, there is even a legend that Takeda Shingen, a warlord from the Sengoku period, ate hōtō as a field meal during battles.

Aichi Prefecture: Kishimen

Kishimen, a flat noodle dish from Aichi Prefecture

Kishimen, beloved as the soul food of Aichi Prefecture, is a type of udon characterized by its flat shape, measuring about 1 mm thick and 7–8 mm wide. There are various theories about the origin of its name, but one suggests it comes from “Goishi-men” (kishimen), a Chinese confection shaped like Go stones. The flat noodles absorb the flavor of the broth well, and traditionally, they are served in a rich soup made from dried frigate mackerel (muroaji) stock combined with tamari soy sauce, which is mainly made from soybeans. Toppings include Nagoya's distinctive red kamaboko (fish cake), aburaage (fried tofu), spinach, and plenty of bonito flakes.

Nagasaki Prefecture: Gotō Udon

Gotō Udon, made in the Gotō Islands of Nagasaki Prefecture, is known for its thin, string-like noodles produced using the hand-stretched method. During the stretching process, locally produced edible camellia oil is used to help prevent the noodles from oxidizing. This also gives the noodles a porcelain-like sheen, a smooth, springy mouthfeel, and a rich flavor. Locally, the best way to enjoy them is with a refined, flavorful broth made from charcoal-grilled “ago” (flying fish), making this a superb delicacy shaped by the unique climate and culture of Gotō.

Toyama Prefecture: Himi Udon

Himi Udon from Himi City, Toyama Prefecture, is a type of udon with over 270 years of history, originating in the mid-Edo period by incorporating techniques from Noto. It was once presented as a tribute to the Kaga Domain. Its greatest feature lies in the artisan techniques of “hand-making, hand-stretching, and hand-twisting,” where the dough is twisted and stretched thin, creating a fine gluten structure. Thanks to this, even as dried noodles, Himi Udon offers a chewy, mochi-like texture and a smooth, pleasant mouthfeel.​​​

Fukuoka Prefecture is said to be the birthplace of udon, with the story that the monk Shoichi Kokushi brought the method back from China during the Kamakura period. The defining characteristic of Hakata Udon is its "soft noodles," which are in stark contrast to those from other regions. It is typically enjoyed with a refined dashi broth, and toppings such as thick-sliced "gobo-ten" (burdock root tempura) and "maru-ten" (deep-fried fish cake) are especially popular among locals. It is also customary to order "kashiwa onigiri" (rice balls with chicken) as a side dish to accompany your udon.​​​

​​​​How is Udon Prepared? 6 Classic Ways to Enjoy Udon in Japan

​​Udon preparation methods and toppings vary by region. While the noodles themselves have a relatively simple and light flavor, there are countless ways to enjoy them. Udon is known for its firm texture and versatility, making it suitable for both soup and stir-fried dishes. Depending on the season or weather, you can enjoy it chilled in summer or hot in winter. Feel free to add your favorite toppings to suit your taste.

Kake Udon (Hot)

Steaming hot Kake Udon is the most basic form of udon. Simply place boiled udon noodles into a bowl of piping hot mentsuyu (noodle soup base). The light soup allows you to fully savor the natural flavor of the udon. Top with chopped green onions, crispy tempura crumbs, and a touch of fresh ginger for a simple yet delicious dish.

Zaru Udon (Cold)

When boiled udon noodles have cooled, they are drained and placed on a bamboo serving tray called a zaru, and this dish is called "Zaru Udon." Typically, chopped green onions, nori seaweed, and ginger are added to a carefully prepared dipping sauce called "mentsuyu." Its refreshing and simple flavor makes it perfect for summer.

Kamaage Udon (Hot)

Kamaage Udon served in a wooden bowl

Kamaage Udon is different from regular soup udon. For Kamaage Udon, the boiled noodles are scooped directly from the pot and served hot in a wooden bowl without cooling. There are various sizes available, from individual portions to large portions for sharing with family. It is usually enjoyed with a special dipping sauce. Scoop the udon from the wooden bowl and transfer it to your own bowl before eating.

Curry Udon (Hot)
