Ehime Prefecture’s local dish “satsuma” is a traditional soup made with fresh white-fish and barley miso.

This dish, made by grilling fish, flaking the flesh, mixing it with miso, thinning it with broth, and pouring it over rice, is a symbol of Ehime’s food culture, combining the boldness characteristic of fishing towns with delicate flavors.
This article comprehensively explains Ehime’s local dish “satsuma,” covering its historical background, detailed recipes, regional characteristics, the origin of its name, and modern preservation activities.
What is Satsuma │ A Traditional Fish Dish of Ehime’s Nanyo Region
“Satsuma” is a local dish of Ehime Prefecture made by flaking grilled white fish flesh in a mortar, combining it with barley miso, thinning it with broth, and pouring it over hot rice. It has been primarily passed down in the Nanyo region, centered on Uwajima City and Yawatahama City.
Basic Characteristics
- Main ingredients: White fish (sea bream, horse mackerel, sardine, rockfish, etc.), barley miso
- Cooking method: Grill fish and flake it, then combine with miso
- How to eat: Pour over hot rice and eat quickly
- Taste: Characterized by the fragrant aroma of grilled fish combined with the richness of barley miso
This dish utilizes fresh fish unique to Ehime Prefecture, which faces the Seto Inland Sea and the Uwa Sea, and developed as a nutritious meal that fishermen could easily eat aboard ships.
Main Areas of Transmission │ Distribution Throughout Ehime Prefecture
While satsuma has been actively made in the Nanyo region of Ehime Prefecture, it is passed down with distinctive characteristics throughout the prefecture.
Nanyo Region (Uwajima City · Yawatahama City)
This is considered the most traditional heartland of satsuma. In Uwajima City, it became established as a fishing town dish from ancient times, and in Yawatahama City, it is known as an important local dish. In these areas, high-quality fish such as sea bream and horse mackerel are often used, with cooking methods that emphasize the flavor of barley miso.
Chūyo and Tōyo Regions
In the Chūyo region such as Matsuyama City and the Tōyo region, satsuma is recognized as a local dish, but there are regional differences in the types of fish used and miso proportions. In inland areas, variations using river fish can be seen.
Food Culture Across Prefectural Borders
Interestingly, a similar dish called “Sanuki satsuma” exists in the western part of Kagawa Prefecture, which borders Ehime. This demonstrates a shared food culture as part of the Seto Inland Sea fishing culture sphere.
History, Origin, and Related Events │ The Origin of the Name Satsuma and Its Transmission
There are multiple theories about the origin of the name satsuma, which is deeply connected to Ehime’s history.
Various Theories About the Name’s Origin
Connection to the Satsuma Domain
One of the most plausible theories is the historical connection to the Satsuma Domain of Kagawa Prefecture. The Uwajima Domain had relations with the Shimazu family of the Satsuma Domain during the Edo period, and one theory suggests the name came from a cooking method of cutting fish into a cross shape, inspired by the Shimazu family’s crest, the “cross pattern.”
The “Sazuma” Theory
Another theory holds that the dish was devised by fishermen’s wives (sa-zuma) to quickly prepare meals for their husbands, which was called “sazuma-jiru” (fisherman’s wife soup), later transforming into “satsuma.”
The Sweet Potato Theory
Some theories suggest it was named because sweet potatoes (satsuma-imo) were used as ingredients in certain regions, but this theory is questioned since sweet potatoes are not used in mainstream recipes today.
Deep Connection with Fishing Culture
Satsuma developed as a dish fishermen could quickly prepare while aboard ships. In an environment where fresh fish was readily available, combining it with preservable miso created an ideal meal that was nutritious, quickly cooked, and practical.
After returning from fishing, consuming hot rice with satsuma allowed weary fishermen to quickly replenish their energy.
Main Ingredients Used │ Fish and Seasonings in Satsuma
What determines satsuma’s flavor is fresh fish and high-quality barley miso. The appeal of this local dish also lies in the fact that the ingredients used vary by region and season.
Types of White Fish
Sea Bream (Tai)
The most premium and traditional ingredient. True sea bream caught in the Uwa Sea has firm flesh and sweetness, making it ideal for satsuma. It is often used when treating guests or for special occasions.
Horse Mackerel (Aji)
Easily obtainable in daily life, its oily, umami-rich flavor goes well with satsuma. It is one of the most popular fish in the Nanyo region.
Sardine (Iwashi)
Common and highly nutritious, it was valued as everyday food for fishermen. The distinctive flavor of blue fish pairs well with barley miso.
Rockfish (Hogo)
Locally called “hogo,” rockfish has a refined white flesh suitable for satsuma. In some regions, it is treated as a premium fish.
Other Fish
Depending on the season and catch, various fish such as mackerel, flying fish, and pike conger are used. In some regions, river fish are also used.
Barley Miso
Barley miso is traditionally used in the Nanyo region of Ehime Prefecture. Compared to rice miso, barley miso has stronger sweetness and a mellow flavor. This barley miso’s richness harmonizes with the fragrant aroma of grilled fish, creating satsuma’s unique taste.
Other Ingredients
- Garnishes: Green onion, ginger, shiso leaves, etc.
- Broth: Broth made from dried sardines or kelp
