What is Satsuma Soup? A Thorough Explanation of the History, Preparation Methods, and Nutritional Value of Kagoshima Prefecture’s Representative Local Cuisine
“Satsuma soup,” a representative local dish of Kagoshima Prefecture. Many people might imagine a dish containing “sweet potatoes” or “satsuma-age (fried fish cake)” based on its name, but in reality, it is a hearty miso soup with chicken as the main ingredient. This dish, which has continued since the Edo period and was nurtured by the culture of samurai warriors, continues to be beloved by the people of Kagoshima Prefecture today.
This article provides a thorough explanation of the charm of this traditional dish, from the historical background of satsuma soup to specific preparation methods, nutritional value, and efforts for preservation and transmission in modern times.
What is Satsuma Soup (Satsumajiru)?
Satsuma soup is a representative local dish of Kagoshima Prefecture made by simmering chicken and multiple root vegetables in miso. Also called “Kagoshima soup,” it differs from ordinary miso soup in that bone-in chicken is cut into chunks, which is its greatest characteristic.
Origin of the Name
The name “satsuma soup” comes from “Satsuma Province,” the former name of Kagoshima Prefecture. In particular, the name was said to be given because of the use of “satsuma chicken,” a local specialty. It has no direct relation to sweet potatoes or satsuma-age, and the naming is based purely on the regional name.
Characteristics of the Dish
The greatest characteristics of satsuma soup are as follows:
- Use of bone-in chicken: By cutting chicken with the bone into chunks, the umami that comes out of the bone spreads throughout the entire soup
- Hearty ingredients: Multiple root vegetables such as daikon radish, taro, burdock, and carrot are included generously
- Miso-based broth: It is characterized by a rich seasoning using miso from Kagoshima Prefecture, such as barley miso or rice miso
- Bold cooking method: As a field ration-style stew, ingredients cut into large pieces are simmered as is
History, Origin, and Related Events
Cockfighting Culture of the Edo Period
The origins of satsuma soup trace back to the cockfighting culture of Satsuma Domain during the Edo period. According to the “Satsuma Old Transmission Collection,” a tradition of cooking and eating chicken existed long ago in Kagoshima Prefecture.
In Satsuma Domain, cockfighting was actively conducted with the aim of raising the morale of samurai warriors and heightening their warrior spirit. There are records that particularly young men aged 15 to 25, called “heko,” were at the center of organizing these cockfights.
Effective Use of Defeated Roosters
Roosters that lost cockfights were killed on the spot and cooked together with vegetables. This is said to be the beginning of satsuma soup. To enable quick cooking in the field, samurai warriors cut chicken meat into chunks with the bone intact and simmered them in a large pot together with whatever vegetables were available.
This bold cooking method had the character of “field ration cooking” and was served at gatherings and meals among men.
Satsuma Samurai Food Culture
Satsuma samurai warriors valued the spirit of simplicity and strength, and in food, they prioritized practicality and nutritional value. Satsuma soup became an established ideal meal for samurai because it could cook meat and vegetables simultaneously in one pot and had excellent nutritional balance.
Spread to Common People
Although satsuma soup was initially eaten among the warrior class, it gradually spread to the general population. Since chicken raising was popular in Kagoshima Prefecture, it became easy for ordinary households to obtain chicken meat, and the dish began to be made for ceremonial occasions and special events.
Main Transmission Regions

Burdock’s aroma and texture serve as an accent. It is rich in dietary fiber and is excellent from a health perspective.

Preparation Method
Prep Work
- Processing chicken
- If using bone-in meat, cut into bite-sized chunks

- Burdock: Lightly scrape the skin and cut diagonally, then soak in water
- Konnyaku: Break apart by hand or into bite-sized pieces with a spoon. Blanch to remove impurities
Cooking Steps
Step 1: Making broth (optional)
Place water and kombu in a pot and let sit for about 30 minutes before heating. Remove the kombu just before boiling. If not using kombu broth, this step can be skipped.
Step 2: Simmering chicken
- Add water (or kombu broth) to a pot, add chicken and sake, and place over medium heat
- Once boiling, carefully remove scum
- Reduce to low heat and simmer for about 10 minutes
Step 3: Adding root vegetables
- Add vegetables in order of cooking time: burdock → daikon radish → carrot → taro
- Simmer 2-3 minutes after each vegetable is added
- Add konnyaku
- Simmer for a total of 15-20 minutes until vegetables are soft
Step 4: Seasoning with miso
- Once vegetables are soft, reduce heat
- Dissolve miso in a small amount of cooking liquid, then add to pot
- Be careful not to boil after adding miso (the aroma will diminish)
- Simmer over low heat for about 5 minutes to blend flavors
Step 5: Finishing
- Taste and add more miso if needed
- Ladle into bowls and sprinkle with thinly sliced green onion
Cooking Tips
- Umami from bone-in meat: When using bone-in meat, slow cooking allows umami to dissolve from the bone
- Vegetable size: Cutting vegetables large makes them more satisfying and less likely to fall apart during cooking
- Removing scum: Carefully removing scum from chicken and vegetables results in a clearer flavor
- Adding miso: Add miso last and avoid boiling to preserve aroma and flavor
Variations
Regional and household differences:
- Sweet version: Add brown sugar for a sweeter, more Kagoshima-style seasoning
