Mizusawa Udon Complete Guide | The History and Charm of Japan’s Top Three Udon, Boasted by Gunma Prefecture
“Mizusawa Udon,” which boasts a history of over 400 years in the Mizusawa district of Ikaho Town, Shibukawa City, Gunma Prefecture. This local specialty, characterized by its transparent, beautiful noodles and strong chewiness, is counted as one of Japan’s top three udon along with Akita’s Inaniwa Udon and Kagawa’s Sanuki Udon. This article provides a comprehensive explanation of the charm of Mizusawa Udon from every angle, from its history to the secrets of its manufacturing method, introductions to famous restaurants, and Gunma Prefecture’s udon culture.
What is Mizusawa Udon | A Local Specialty Representing Gunma Prefecture
Mizusawa Udon is hand-made udon born in the Mizusawa district of Ikaho Town, Shibukawa City, Gunma Prefecture. This region has long been known for wheat cultivation, and blessed with high-quality spring water, making it an ideal environment for udon production.
Status as One of Japan’s Top Three Udon
Mizusawa Udon is widely recognized as one of Japan’s top three udon alongside Sanuki Udon (Kagawa Prefecture) and Inaniwa Udon (Akita Prefecture). Unlike the strong chewiness of Sanuki Udon and the delicate thin noodles of Inaniwa Udon, Mizusawa Udon is characterized by its unique texture combining transparent, beautiful appearance with firm elasticity.
Characteristics of Mizusawa Udon
The greatest characteristic of Mizusawa Udon lies in its transparency and strong chewiness. The noodles are medium to thick, and the lustrous sheen when boiled is beautiful. One bite reveals elastic, chewy texture that spreads throughout the mouth. Made with only wheat flour, salt, and the clear water of Mizusawa through an additive-free method, the original flavor of wheat stands out.
It is often served as cold zaru udon and is typically eaten with sesame sauce or soy sauce. Some restaurants serve it warm, but to fully enjoy the transparency and chewiness that characterize Mizusawa Udon, eating it cold is recommended.
The History of Mizusawa Udon | Walking Together with Mizusawa Temple for 400 Years
The Birthplace: Mizusawa Temple (Mizusawa Kannon)
The history of Mizusawa Udon dates back approximately 400 years to the early Edo period. Mizusawa Temple (commonly known as Mizusawa Kannon) in Ikaho Town, Shibukawa City, Gunma Prefecture, was the sixteenth temple on the Bandō Thirty-Three Kannon Pilgrimage and attracted many worshippers. Mizusawa Udon is said to have begun when hand-made udon was served to pilgrims at the temple’s front gate.
The area around Mizusawa Temple was abundant with clear spring water, and udon made using this water became well-regarded among pilgrims. Gradually, more udon shops appeared at the temple’s front gate, and the Mizusawa district became known as the “Land of Udon.”
The History of Tamariya, the Original
Tamariya, known as the original Mizusawa Udon restaurant, is said to have been founded in the tenth year of Tensho (1582). Over 400 years, it has continued to preserve traditional manufacturing methods and has been the driving force in spreading the name of “Mizusawa Udon” throughout Japan. Established restaurants like Tamariya pass down techniques inherited through generations, conveying flavors from the past to the present.
The Relationship with Ikaho Hot Spring
The Mizusawa district is located near Ikaho Hot Spring, one of Gunma Prefecture’s leading hot spring destinations. After Ikaho Hot Spring developed as a healing spa from the Meiji era onward, a course became established where hot spring visitors would worship at Mizusawa Temple and eat Mizusawa Udon on their way back. The combination of hot springs and local cuisine created a synergistic effect as a tourist resource, greatly contributing to increased recognition of Mizusawa Udon.
The Manufacturing Method of Mizusawa Udon | The Secret Behind Its Transparency and Strong Chewiness
Carefully Selected Raw Materials
The secret to Mizusawa Udon’s deliciousness lies in carefully selected raw materials, though simple. Only wheat flour, salt, and Mizusawa’s clear water are used. The additive-free manufacturing method, which uses no additives, brings out the original flavor of wheat and creates transparent noodles.
Primarily medium-strength flour is used, with some restaurants creating their own blends. Many restaurants use Gunma-grown wheat, and local production for local consumption efforts are advancing. Salt plays an important role in giving the noodles chewiness, while water from Mizusawa’s spring water or groundwater is used to achieve a clean, clear flavor.
Traditional Hand-Beating Method
Most Mizusawa Udon is still made by hand today. The process is carried out in the following steps:
- Water mixing: Salt water is added to wheat flour and mixed evenly. This process determines how the flour and water bond.
- Kneading: Kneading the dough vigorously forms gluten, resulting in noodles with strong chewiness. Artisan skill is required to adjust kneading time and force according to temperature and humidity.
- Resting: The kneaded dough is left to rest for a certain period, allowing gluten to mature and the noodles to gain extension and elasticity.
- Stretching: The dough is evenly stretched with a noodle roller. Uniform thickness affects the texture of the cooked noodles.
- Cutting: The stretched dough is folded and cut with a knife into uniform thickness. Mizusawa Udon is characteristically cut to medium to thick size.
- Boiling: Cooked in plenty of boiling water. Cooking time is adjusted based on noodle thickness, but generally takes about 15 minutes.
- Cooling: The cooked noodles are tightened in cold water, bringing out transparency and chewiness.
The Power of Water Creating Transparency
The transparency characteristic of Mizusawa Udon is largely attributed to the high-quality water of the Mizusawa district. Water emerging from the Haruna Mountain system has good mineral balance and few impurities, so when the noodles are boiled, there is little cloudiness and a lustrous finish is achieved. When tightened in cold water, this clear water also firms the noodle surface, resulting in shiny, beautiful noodles.
