Complete Guide to Jako-Ten | Thorough Explanation of the History, Manufacturing Method, and How to Eat This Local Specialty Dish Boasted by Ehime Prefecture
Jako-ten, beloved in the Nanyo region of southern Ehime Prefecture since ancient times, is a traditional fish cake product made by grinding small fresh fish caught in the Uwa Sea with bones and skin intact, then deep-frying it. Far from being merely fried fish cake, it is a local specialty dish representing Ehime that embodies the region’s history and food culture, and continues to be cherished by many people today.
This article provides a detailed explanation of everything about jako-ten, from its historical background, manufacturing methods, nutritional value, diverse ways of eating it, regional differences, and efforts for preservation and inheritance.
What is Jako-ten (じゃこてん)?
Jako-ten is a specialty product made primarily in the coastal areas of the Nanyo region of Ehime Prefecture, especially centered around Uwajima City and Yawatahama City. It is a fish cake product made by deep-frying ground fish from local waters, and is classified as fried fish cake.
Its greatest characteristic lies in the method of grinding small fish including skin and bones. This manufacturing method allows one to experience the original flavor of fish and its nutrition fully, creating a unique flavor and texture that sets it apart from other processed fish products. The deep umami of fish that spreads the more you chew it, along with a subtle fragrant aroma, creates a taste that is unforgettable once tasted.
Locally, it is often simply called “tempura,” and historically in Uwajima, all fried fish pastes were called “tempura,” with those containing skin and bones like jako-ten specially called “kawa-tempura” (skin tempura). This naming convention remains rooted in the region today, and jako-ten is cherished as a soul food in the daily lives of Ehime residents.
Main Transmission Regions
The main manufacturing and transmission regions of jako-ten are in the Nanyo region of southern Ehime Prefecture, particularly in the following areas.
Uwajima City
Uwajima City is said to be the birthplace of jako-ten, and is the region where the most traditional manufacturing methods are preserved. At fishing ports facing the Uwa Sea, fresh small fish are unloaded, and many fish cake shops manufacture jako-ten using traditional methods. Uwajima’s jako-ten primarily uses Haranbo (Hotaru jako) and is characterized by strong fish flavor and firm texture.
Yawatahama City
Yawatahama City is also a fishing region facing the Uwa Sea where fish processing has developed as a traditional industry. Yawatahama’s jako-ten uses various types of small fish such as lizardfish, and many feature unique flavors different from Uwajima. Because the types of fish used and their proportions differ by region, each shop’s individual flavors can be enjoyed.
Iyo City and Other Regions
Jako-ten is widely manufactured and sold in other regions of Ehime Prefecture, including Iyo City. Fish cake shops in each region exert their own ingenuity and offer original jako-ten using fish caught locally, becoming established as a local dish throughout Ehime Prefecture.
History, Origins, and Related Events
The Origins of Jako-ten
The history of jako-ten dates back to the early Edo period. It is said that when Date Hidetatsu, the eldest son of Sendai Domain Lord Date Masamune, became the first domain lord of Uwajima Domain in Genwa 1 (1615), missing his hometown of Sendai, he brought fish cake craftsmen with him, which marked the beginning of jako-ten.
Sendai had developed a fish cake culture including sasaakamaboko (bamboo leaf fish cake), but in Uwajima, it developed uniquely by utilizing the small fish abundant in the Uwa Sea. At that time, small fish called “jako” (miscellaneous fish) were considered less valuable than larger fish, but a technique of grinding them with skin and bones intact and deep-frying them was developed, spreading widely as a valuable protein source for common people.
The Origin of the Name
The name “jako-ten” is a combination of the small fish used as raw material (miscellaneous fish = jako) and “tempura” meaning fried foods. In the Uwajima region, there was a custom of calling all fried fish paste “tempura,” and among these, those made from small fish became established as “jako-ten.”
Connection with Regional Culture
Jako-ten has played an important role not only as an everyday food but also as a ceremonial and festival food. The custom of deep-frying jako-ten at home or using it as a gift during New Year, Obon, local festivals and other occasions remains today. Freshly fried jako-ten in particular has exceptional deliciousness and has been cherished as a special occasion dish.
Main Ingredients Used
Haranbo (Hotaru Jako)
The most representative primary ingredient for jako-ten is Haranbo (Hotaru Jako). This small fish caught in the Uwa Sea is about 10 centimeters in body length and is characterized by low fat content and mild taste, yet strong umami. Particularly in traditional Uwajima jako-ten, using primarily this Haranbo creates the unique flavor and resilient texture.
Lizardfish (Eso)
Lizardfish is a white fish widely used as an ingredient for fish cake and is also frequently used in jako-ten. Its soft meat is easy to grind into paste, creating a smooth texture. By blending lizardfish, jako-ten finishes with good mouthfeel and refined flavor.
Other Small Fish
Various small fish caught in the Uwa Sea are used, including red seabream, horse mackerel, mullet, and sea bream. The types of fish used and their proportion ratios differ by manufacturer, becoming an important element in creating each shop’s unique flavor. As the fish caught changes by season, using seasonal fish allows one to enjoy different flavors throughout the year.
Supplementary Materials
Basically made with simple ingredients, but flavor is adjusted by adding salt, sugar, mirin, sake and other seasonings. A small amount of starch may be added, but in traditional manufacturing methods, the fish proportion is high, and the original fish flavor is valued.
Manufacturing Methods and How to Make It
Traditional Manufacturing Method
The traditional manufacturing process of jako-ten centers on skilled handwork.
- Fish Preparation: Fresh small fish are washed and gutted. However, skin and bones are kept intact, which is characteristic of jako-ten.
- Making Paste: Fish is ground using a stone mortar or machine. Traditionally, using a stone mortar where craftsmen grind by hand allows fish fibers to remain appropriately, creating the unique texture.
- Seasoning: Salt, sugar, mirin and other flavorings are added to the paste and thoroughly kneaded together. This process determines the taste, making a craftsman’s experience and intuition crucial.
- Shaping: The kneaded paste is placed in a wooden frame and pressed into a flat oval shape. The typical thickness is about one centimeter.
- Deep-frying: Deep-fry in oil at 170-180 degrees Celsius until the surface becomes a golden-brown color and a fragrant aroma rises, resulting in a crispy exterior and fluffy interior.

Nutritional Value and Health Benefits
Jako-ten is a highly nutritious food because it uses small fish whole.
Rich in Calcium
Because bones are ground whole into the paste, it contains abundant calcium. The calcium content per 100 grams is several times that of regular fish cake, making it effective for bone health maintenance and osteoporosis prevention. It serves as an excellent calcium source for children in growth phases and elderly people.
Essential Fatty Acids Such as DHA and EPA
It is abundant in DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) and other essential unsaturated fatty acids abundant in oily fish. These components aid in brain development and function maintenance, blood-thinning effects, and prevention of lifestyle-related diseases.
High-Quality Protein
Rich in high-quality protein derived from fish meat, contributing to muscle maintenance and immune enhancement. It is also easily digestible and absorbed, making it a suitable nutrient source for elderly people and children.
Vitamins and Minerals
By using whole fish, one can obtain various vitamins and minerals including B vitamins, vitamin D, iron, and zinc. These play important roles in metabolism promotion and immune function maintenance.
Healthy Fried Food
While a fried food, fish fat consists primarily of high-quality unsaturated fatty acids, and in appropriate amounts, can be considered a health food. However, calories are approximately 200-250kcal per 100 grams, so care should be taken against overeating.
Eating Methods and Diverse Ways to Enjoy
One of the attractions of jako-ten is its diverse eating methods. While delicious eaten plain, various cooking methods allow one to enjoy different flavors.
Eating Plain
The simplest way and the one that best allows one to enjoy jako-ten’s original flavor. Eat freshly purchased items plain, or warm lightly. Typically eaten with soy sauce, ginger soy sauce, ponzu and other condiments. Because it is simple, the fish’s umami and fragrant aroma are transmitted directly.
Eating Grilled
Lightly grilling in a frying pan, toaster oven, or fish grill makes the surface crispy and fragrant while the interior becomes fluffy. Grilling allows fat to drip away, making it more healthful. Served with grated daikon and soy sauce, or yuzu pepper, it becomes refreshing.
As a Simmered Dish
Eating jako-ten as an ingredient in oden or simmered dishes is also popular. Jako-ten becomes soft and juicy when simmered as broth soaks in. When simmered together with daikon, taro, and konnyaku, fish umami transfers to other ingredients, creating a deeply flavored simmered dish.
In Stir-fries
Adding to vegetable stir-fries, stir-fried udon, yakisoba and other dishes adds fish umami, giving the entire dish depth of flavor. Stir-fried with cabbage, bean sprouts, peppers, etc. and seasoned with soy sauce or oyster sauce becomes a rice-pairing side dish.
Jako-ten Curry
In Ehime Prefecture, adding jako-ten to curry is also popular. The fish umami of jako-ten matches exquisitely with curry spices, creating a unique deliciousness. It is also known as a local specialty curry.
As Ingredients in Udon and Soba
Using jako-ten as a topping for udon and soba noodles is also standard. Jako-ten soaked in warm broth becomes soft, and combined with broth umami, becomes excellent. Many udon shops in Ehime Prefecture have jako-ten udon on their menus, cherished by local people.
As Salad Topping
Thinly slicing jako-ten as a salad topping adds protein, creating a nutritionally balanced dish. It pairs especially well with Japanese dressing and is noted as a healthful way to enjoy it.
