Complete Guide to Izumo Soba | History, Characteristics, and How to Enjoy Shimane Prefecture’s Representative Local Cuisine
Izumo soba, which has been beloved in the Izumo region of Shimane Prefecture since ancient times, is counted as one of Japan’s three great soba dishes and is a traditional local cuisine. Known for its distinctive dark color, rich flavor, and high nutritional value, this soba is enjoyed daily not only by tourists but also by local residents.
This article comprehensively introduces information about Izumo soba, from its historical background and manufacturing characteristics to dining etiquette, how to make it at home, and renowned restaurants to visit.
What is Izumo Soba | One of Japan’s Three Great Soba Dishes, Proud of Shimane Prefecture
Izumo soba (いずもそば) is a local cuisine widely eaten in the Izumo region of Shimane Prefecture. Along with “wanko soba” from Iwate Prefecture and “Togakushi soba” from Nagano Prefecture, it is nationally recognized as one of Japan’s three great soba dishes.
The Greatest Characteristic of Izumo Soba
The most distinctive feature of Izumo soba lies in a unique milling method called “hikigurumi” (whole-grain milling). While ordinary soba is milled after removing the outer shell of the buckwheat grain, Izumo soba is milled with the raw buckwheat grain (with its hull intact) almost entirely as is.
This method creates the following characteristics:
- Black color: Because the hull is milled together, it has a darker color than typical soba
- Strong aroma: The original buckwheat aroma stands out, offering a richly flavored taste
- Good texture: It has firm elasticity and a chewy mouthfeel
- High nutritional value: Nutritional elements like rutin contained in the hull are consumed together
Main Transmission Regions
Izumo soba has been transmitted primarily in the Izumo region of Shimane Prefecture. It is especially widely eaten in areas centered around Izumo City and Matsue City, with many soba restaurants still operating today. Renowned restaurants are concentrated around Izumo Taisha, and enjoying Izumo soba as part of a pilgrimage has become the standard course.
History and Origins of Izumo Soba | A Culture Transmitted Together with the Matsudaira Clan
The history of Izumo soba dates back to the early Edo period. While there are various theories about its origin, the most widely accepted is the theory of transmission via the Matsudaira clan.
Lord Matsudaira Naomasa and Soba Craftsmen
In 1638 (Kanei 15), when Matsudaira Naomasa, the first daimyo of the Matsue Domain, was transferred from the Shinshū Matsumoto Domain to Izumo, he is said to have brought soba craftsmen with him, marking the beginning of Izumo soba. Shinshū was known as a production area for soba, and the transmission of this technique to the Izumo region led to the flourishing of Izumo soba culture.
Independent Development in the Izumo Region
The soba culture transmitted from Shinshū underwent independent development through fusion with the climate, soil, and food culture of the Izumo region. In particular, the “hikigurumi” milling method was established in the Izumo region and became the defining characteristic of Izumo soba.
Throughout the Edo period, Izumo soba became a food beloved across a wide range of people, from the warrior class to commoners, and became established as food for celebrations and everyday meals.
Development After the Modern Era
Since the Meiji period, the tradition of Izumo soba has been passed down, and by the Showa period it began to be recognized as a tourism resource. Particularly as pilgrimage visits to Izumo Taisha increased, Izumo soba gained national recognition as a local cuisine representative of Shimane Prefecture.
Today, with more restaurants both preserving tradition and incorporating new approaches, Izumo soba culture continues to evolve.
Manufacturing Method of Izumo Soba | The Unique Flavor Created by “Hikigurumi”
The taste of Izumo soba is determined by the “hikigurumi” (whole-grain milling) method. Here, let’s examine in detail how Izumo soba is made.
Main Ingredients Used
The basic materials for Izumo soba are as follows:
Soba flour
- Milled from raw buckwheat grain (buckwheat grain with hull)
- The higher the percentage of soba flour, the stronger the flavor
- Most restaurants use 100% soba or 90% soba
Binder
- Wheat flour may be used
- No binder is used for 100% soba
Water
- Using clear water from Shimane Prefecture
- Water quality greatly affects the taste of soba
Characteristics of Hikigurumi Milling
While ordinary soba flour is made by removing the outer husk from the buckwheat grain and milling only the inner portion, the “hikigurumi” method for Izumo soba:
- Uses raw buckwheat grain as is: The hull is barely removed, and the entire buckwheat grain is milled together
- Does not perform staged milling: Powder sorting is not done in detail; everything is milled at once
- Does not lose nutrients: Nutritional elements like rutin and polyphenols contained in the hull are consumed together
This method produces soba that is darker in color, stronger in aroma, and higher in nutritional value than ordinary soba.
The Soba-Making Process
The process of making Izumo soba basically follows the same steps as other soba, but because the flour has different properties, the craftsman’s skill becomes particularly important:
- Water mixing: Add water little by little to soba flour in a bowl and mix until the flour becomes granular
- Kneading: Once the dough comes together, knead it thoroughly by pressing down with the palm of your hand. Continue kneading for 5-10 minutes until the surface of the dough becomes smooth
- Stretching: Round the dough, place it on a powder-dusted board, and stretch it uniformly from the center outward with a rolling pin. Aim for a thickness of about 2-3mm
- Cutting: Dust the stretched dough with powder, fold it in a fan pattern, and cut evenly to 2-3mm width with a knife
- Boiling: Bring plenty of water to a boil in a large pot, add the soba, and boil for about 3-5 minutes (adjust according to thickness). Once boiled, rinse in cold water
How to Eat Izumo Soba | Warikodan Soba and Kamaage Soba
Izumo soba has unique ways of eating it that are not found in other regions. The two representative styles are “warikodan soba” and “kamaage soba.”
Warikodan Soba | The Standard Style of Izumo Soba
Warikodan soba is the representative way of eating Izumo soba. “Warikodan” refers to a round lacquered dish in three tiers.
Characteristics of warikodan soba:
- Three tiers (or sometimes two or four) of round dishes contain bite-sized portions of soba
- Each tier is accompanied by condiments (chopped green onion, shredded nori seaweed, grated daikon with red pepper, bonito flakes, etc.)
- Eaten by pouring sweet-salty broth directly over it
Dining etiquette:
- Begin eating from the top tier
- Pour an appropriate amount of broth and mix with condiments
- Once you finish one tier, transfer the remaining broth to the next tier
- Repeat for all three tiers
- Finishing by pouring soba hot water into the broth to make a broth drink is also recommended
This method allows the broth to become progressively more flavorful as you move from the first to the third tier, allowing you to enjoy a change in taste.
Kamaage Soba | Simple Deliciousness
Kamaage soba is a style where boiled soba is served without being rinsed in water, served in a bowl along with the cooking water (soba hot water).
Characteristics of kamaage soba:
- Warm soba and soba hot water are served together
- You can directly feel the warmth and aroma of the soba
- Eaten by adding condiments and broth
How to eat:
- Add condiments to the warm soba in the bowl
- Pour an appropriate amount of broth
- Enjoy the soba along with the hot water
- You can enjoy the softness and warmth of the soba
Kamaage soba is especially popular during cold seasons and warms you from the core.
Other Ways of Eating
Beyond the traditional warikodan and kamaage styles, various arrangements can be enjoyed:
- Zaru soba: Cold soba rinsed in water, served on a bamboo strainer, eaten with dipping sauce in the typical style
- Warm kake soba: A standard way of eating with warm broth poured over
- Tempura soba: A luxurious version with tempura
- Kamo nanban soba: Warm soba made with duck meat and green onion
Occasions and Seasons for Eating
Izumo soba is eaten year-round, not limited to specific seasons or occasions. However, it is especially favored at:
- New Year: As year-end soba, and as part of New Year’s dishes
- Celebrations: At auspicious occasions such as weddings or longevity celebrations
