Jakoten: A Fried Fish Cake from the Uwa Sea Coast
This version uses fish skin and fish flesh, ground into a paste and fried as flat ovals. It keeps the skin. It does not add bones, vegetables or herbs to the paste.
Along the Uwa Sea, in the Nanyo region of southern Ehime Prefecture, the towns of Yawatahama and Uwajima have a long history of processing local fish. Jakoten is one of those foods. Small fish are ground into a paste, mixed with wheat flour, egg and salt, shaped into flat ovals called koban, and fried. Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) lists Nanyo as the main region where the dish has been handed down. People there eat it all year round, as a side dish with rice or alongside a drink.
The recipe here follows a single household formula published on MAFF's regional cooking pages and supervised by the Ehime Tourism Association. It serves four and uses 200g of lizardfish skin (eso) and small horse-mackerel flesh (ko-aji) together, plus salt, flour, half an egg and oil for frying. It is a home version that makes use of the fish skin. It is not the bone-in method used by Uwajima producers, which is described separately below. For more dishes from across the country, see Japanese recipes.
This recipe has not been kitchen-tested by Sekai Gohan. The amounts and steps come from the published formula. The oil temperature and the center-heating check come from separate general guidance from Japanese public agencies. They are not values given in the jakoten recipe itself.
How this recipe reads the published formula
The MAFF page gives the fish as one combined amount: 200g of lizardfish skin and small horse-mackerel flesh. It does not say how much of each to use, so this article does not set a ratio. Flour and frying oil are both listed as "as needed." The page gives no flour weight, number of cakes, thickness, frying temperature, frying time or storage period, and none of those are invented here.
The written method mentions only the lizardfish skin: chop it finely with a knife, grind it well, add salt, flour and egg, and mix until firm. The small horse-mackerel flesh appears in the ingredient list but not in the steps. Our editorial choice is to chop the flesh along with the skin and grind the two together before adding the salt, flour and egg. That step is ours, not the recipe author's. In the method below, the egg is a whole egg beaten and then halved, and the flour goes in a little at a time until the paste is firm enough to hold an oval shape.
What Jakoten Is: Skin, Flesh and a Firm Paste
MAFF describes jakoten as small fish ground with their skin and bones, mixed with wheat flour, egg and salt, shaped into ovals and fried. That general description covers bones, but the quantified household recipe on the same page lists only lizardfish skin and small horse-mackerel flesh. This article follows the ingredient list and does not add bones. MAFF also notes that the photo on its page may differ from the recipe, so neither the fish ratio nor the presence of bones should be guessed from that image.
Commercial jakoten often has a texture that comes from grinding whole small fish. Yasuoka Kamaboko, a producer in Uwajima, describes its own jakoten as having a gritty, jari-jari mouthfeel. That description belongs to the company's product and method. It is not a promise about this home version.
Fish Processing in Uwajima and Nanyo
MAFF explains that fish processing has thrived in Yawatahama and Uwajima on the Uwa Sea coast. For the name, it gives two theories without choosing between them. One says zako, a word for mixed small fish, became jako. The other traces the name to harambo, also called hotaru-jako, a small fish used as a raw material. MAFF also passes on a story that in 1615, Date Hidemune, lord of the Uwajima domain, invited kamaboko (fish-cake) artisans from Sendai. The page presents this as something that "is said." It is a tradition, not a confirmed date in a timeline.
Producers describe their own methods in more detail. Yasuoka Kamaboko says it uses hotaru-jako as its main fish together with other small fish from nearby waters, and adjusts the blend of species. The company removes the heads and innards, grinds the fish with skin and bones, works the paste in a stone mortar without rinsing it in water, shapes ovals and fries them in rapeseed oil. A 2007 interview with the head of the Uwajima Kamaboko Cooperative, published by Hakata Salt, describes a similar process at that producer: heads and innards removed, fish minced with bones and skin, salt worked in, ovals shaped and fried at 180°C. The same interview introduces a cooperative guideline for "Uwajima jakoten": fish from Uwajima as the main ingredient, with everything from paste to finished product done in Uwajima. That describes the situation at the time of the interview. It is not a statement about any current trademark, legal protection or certification. A home batch made from this recipe is not that product.
MAFF notes that recipes vary by region and household. The household formula below is one published example. It is not the only way jakoten is made.
Ingredients (Serves 4)
Use fish skin and flesh that are already cleaned and ready to cook, with no heads, innards or bones. Keep them refrigerated until you start.
This recipe contains fish, egg and wheat.
Equipment
- Kitchen knife
- Cutting board and tray used only for raw fish
- Suribachi (Japanese ridged mortar) and pestle
- Two small clean bowls for the egg
- Deep pot for frying, with plenty of room below the rim
- Frying thermometer
- Food thermometer with a probe
- Slotted spoon or mesh skimmer
- Wire rack or absorbent paper for draining
- Separate clean plates and utensils for the cooked cakes
A home food processor can stand in for the mortar, but the texture may change.
Choosing the Fish, Flour and Oil
Fish. Lizardfish skin is hard to find in ordinary supermarkets. Ask a fishmonger whether they can supply lizardfish skin and small horse-mackerel flesh, and whether they can separate the skin from the flesh for you. If the shop portions it, confirm that the skin and flesh together come to 200g.
Other fish or store-bought surimi would make a different dish, not this recipe. The same goes for Uwajima-style hotaru-jako. Any such version is a separate, untested idea.
Flour. Any ordinary wheat flour works. Cake flour or a light flour such as Japanese hakurikiko is a household option. Do not replace the flour with potato starch.
Oil. Use any oil suitable for deep-frying.
Method: Chop, Grind, Firm, Shape and Fry
The paste is ready when it holds a firm oval shape. The cakes are done when the center of the thickest one has reached 75°C and been held there for at least 1 minute. Browning alone does not mean they are cooked through.
Keep raw fish, and everything it touches, away from cooked cakes and garnishes. Wash your hands after handling raw fish.
Serving: Freshly Fried, Plain or with Simple Condiments
MAFF suggests trying jakoten freshly fried, either as it is or with grated daikon, ginger and soy sauce. The Hakata Salt interview also mentions grated daikon with ponzu, and ginger with soy sauce. These are condiments served on the side. They are not mixed into the paste. Use clean utensils for the garnishes, separate from anything that touched raw fish.
In Nanyo, according to MAFF, jakoten goes into everyday dishes too. People use it in Uwajima oden, in udon and in tempura curry. Those dishes use finished jakoten. They are not part of this recipe.
Ways Jakoten Varies
These are versions described in the sources. Only the first one is the recipe in this article.
| Version | What it is | How it relates to this recipe |
|---|---|---|
| Lizardfish skin and small horse-mackerel flesh | The household formula published by MAFF | The recipe in this article |
| Bone-in artisan method | Fish ground with skin and bones after removing heads and innards, as producers describe | Described for background. Do not add bones to this recipe |
| Hotaru-jako-centered Uwajima style | A producer's blend of hotaru-jako and other local small fish | A different formula, not tested here |
| Condiments on the side | Grated daikon with ginger and soy sauce, or with ponzu | Served alongside, never mixed in |
| In other dishes | Oden, udon, tempura curry | Uses for finished jakoten |
Troubleshooting and Food Safety
| Problem | What to do |
|---|---|
| The paste is too soft to hold an oval | Add a little more flour and mix again until it holds its shape |
| The oil temperature drops a lot when cakes go in | Fry fewer at a time, covering no more than about half the oil surface |
| The cakes look brown, but you're not sure they're cooked | Check the center of the thickest cake with a thermometer. Color does not prove the center is cooked |
| The center has not reached 75°C for 1 minute | Return the cake to the oil and check again. Next time, shape the cakes thinner |
| Cakes cook unevenly | Turn them partway through frying |
Keep the raw fish refrigerated until you use it. Use separate boards, trays and utensils for raw fish, and keep them away from cooked cakes and garnishes. Eat only cakes that are fully cooked.
Do not leave cooked jakoten at room temperature for a long time. Cool any leftovers quickly in a shallow container, then refrigerate them right away.
Frequently Asked Questions
Which part of Japan is jakoten from?
MAFF names the Nanyo region of Ehime Prefecture as the main area where it has been handed down. Uwajima and Yawatahama, on the Uwa Sea coast, are known for fish processing.
Does jakoten contain fish bones?
The general description and producers' methods involve grinding small fish with their bones. The quantified household recipe used here lists only lizardfish skin and small horse-mackerel flesh. It gives no amount for bones, so this article adds none. There is no claim here about calcium or other health benefits.
Why does the method chop the horse-mackerel flesh when the recipe only mentions the skin?
The published method mentions only the lizardfish skin, but the small horse-mackerel flesh is in the ingredient list. Chopping and grinding the flesh along with the skin is our editorial choice to fill that gap. It is not something the recipe author wrote.
Can I make it without hotaru-jako or lizardfish skin?
This recipe already uses lizardfish skin and small horse-mackerel flesh, not hotaru-jako. Replacing the fish with other species or store-bought surimi would make a different dish. That has not been tested here.
How long should I fry it?
The recipe gives no frying time, and the general oil-temperature guide does not translate into minutes. Frying time depends on how thick the cakes are and on your pot. Check the thickest cake: the center should reach 75°C and hold for at least 1 minute.
Is homemade jakoten the same as "Uwajima jakoten"?
No. The Uwajima cooperative guideline described in the 2007 interview concerns fish from Uwajima, with the paste and finished product both made in Uwajima. A home batch from this recipe is not that product.
Has this recipe been tested?
No. This recipe has not been kitchen-tested by Sekai Gohan. The amounts and steps follow the published household formula. The temperatures are general guidance and have not been measured for this dish.
