    Unadon (うな丼)

    Today, eel is a very popular food and fish not only in Japan but also overseas. Unadon is a traditional Japanese food that uses grilled eel. It is one of Tokyo’s specialty cuisines from the Edo period, and locals usually served this by putting rice in a bowl then sprinkling sauce and putting eel kabayaki on it. If you know about Unajyu then I will let you know about Unadon or Unagi-don.


    Unadon (うな丼)

    Unadon (うな丼) is an abbreviation for Unagi-don or Unagi donburi, but it is popularly called by Unadon. Unagi (うなぎ) means eel in Japanese and donburi (丼) is “a large helping of rice covered in meat, fish, and/or vegetables, all served in one big bowl”.

    What is Unadon?

    Unadon (うな丼)

    Unadon (うな丼) or Unagi Donburi (うなぎどんぶり) is a traditional Japanese rice bowl dish in which the Eel kabayaki is on top of white rice. It is one of the local dishes of Edo and Tokyo. It is also known as eel rice (manmeshi or mamushi). Locals make Unagi don or unadon by putting rice in a bowl then sprinkling sauce and putting eel kabayaki on it. Depending on the area, some served the rice from the top to cover the eel. Although it is called “don,” round lacquer bowls are often used instead of ceramics. The sauce is mainly of soy sauce and mirin and many shops used it carefully by adding a little bit. Japanese believed that the fat and flavor of eel, burnt skin, and charcoal are added to create richness and depth and will mature into a taste unique to long-established shops. 

    History of Unadon

    Unadon (うな丼)

    Birth of eel kabayaki 

    Japanese already eaten eels as kabayaki since the Muromachi period in 1399. In the Muromachi period, locals cut the eel into a cylinder shape and grilled on skewers, and called it Kabayaki. Since then, many eels have lived in wetlands due to reclamation due to development in the Edo period, and eel kabayaki has become very popular. Therefore, Kabayaki began to take root in earnest in the Edo period.

    Birth of Unadon

    Unaju is the standard eel, but Unadon is as popular as Unaju. Unadon is popular because the Japanese steamed it with the heat of Donburi rice, making the meat of eel softer and hotter. The history of Unadon dates back to the Edo period when the food culture of eels became established in earnest, but there are several reasons why Unadon became the history and origin. A predominant theory is that in the latter half of the Edo period, a person named Imasuke Okubo, a gold maker of the play in Sakai Town, Nihonbashi, Edo (Tokyo) started selling Unadon in the playhouse. 

    At the beginning of the eel bowl, it was common to put the roasted eel between rice and rice so that it wouldn’t get cold and put it on top of the rice. It was easy, and gradually locals just put the eel on top of the rice. On the other hand, in Kansai, they do not steam the eel in advance, so it does not collapse, and as a result, the style of sandwiching it between rice remains until now. In the Meiji era, locals called it Unagidonburi, and soon after the Japanese abbreviated it as Unadon, they established that name.

    How do Japanese price Unagi?

    Unadon (うな丼)

    The price of the unagi is divided into three categories.

    Size of unagi used

    Unagi has three sizes namely, the three-tailed size, four-tailed size, and five-tailed size. The price is set per kg of these three. If it is 5-tailed fish, 1 fish is 200g, 250g for 4 tail size, and 3-tailed fish is around 330g, which is around 330g. The larger the size, the lower the unit price per kg is set. 

    Types of unagi used

    The place of origin of eels is on the label affixed to the unagi pack at supermarkets. In most cases, the price label says “domestic,” “Chinese,” “Taiwan,” “Indonesian,” and so on. In the case of domestic products, the product label says “Kagoshima”, “Tokushima”, “Miyazaki”, “Shizuoka”, “Lake Hamana” etc. The price is a way of distinguishing that everyone knows. Naturally, domestic products are expensive. Chinese products are about half the price of domestic products. Most of the eels offered at the shop for around 2000円 are farmed eels. Natural unagi has a yellow tummy and a thin body. The texture when one eats it after baking is firmer and lighter. While the cultured-unagi has a white tummy and large body. The eel is characterized by low fat and no odor. 

    Based on the restaurants pricing

    There are franchisee stores and high-end restaurants that sell unagi. However, the restaurant uses different unagi and franchisee power to cost down. One example of a franchisee is the Unatoto that has Unadon for only 550円 and twice the size of that called “Unadon Double” cost only 1,000円. Another cheap franchisee is the well-known Yoshinoya. They serve the lowest price Unadon here for 788円 per serving (866円 including tax), 1,218円 for two (1,339円 including tax) and 1,648円 for three servings (1,812円 including tax). While the high-end restaurants in Japan serve their Unadon for 3,200円, Eel kabayaki, and Eel Shiroyaki for 2,800円. Their unadon comes with steamed eggs, pickles, and liver soup. 

    Types of Unagi

    Unadon (うな丼)

    Japanese eel

    It is an elongated cylinder and the eyes are small and there is no belly fin. A dark brown back with a back fin that connects to the tail. It has a pale yellowish-white belly. Compared to the thick and short eels in Europe, the Japanese eel has an elongated impression. Due to overfishing, the natural Japanese eel is now an endangered species, and various efforts locals made to conserve the species.

    European eel

    It is the only eel distributed in Europe. After the war, it was imported into Japan in large quantities and cultivated. The appearance is almost the same as the Japanese eel, and it has an elongated cylindrical body. The taste is almost the same, but it tends to be more greasy than Japanese eels.

    Most of the eels distributed in Japan are Japanese eels and European eels.

    Giant mottled eel

    The eels distributed in Japan are the Japanese eel and this giant mottled eel. As the name suggests, it is larger than an eel and can reach a maximum length of 2m and a weight of 20kg. However, unlike Japanese eels, the number of eels that locals catch is small and the taste is inferior, so they do not generally distribute it for food.

    Natural eels and farmed eels

    Natural eels are rarely found on the market as they are. However, aquaculture is not a “complete aquaculture” that grows from eggs, but a “livestock-type” farmed eel that catches and raises young and adult fish.

    What is the best season of Unagi?

    Unadon (うな丼)

    Unagi is served year-round; however, it is especially popular during the summer months due to properties thought to increase stamina and heat tolerance. However, it seems that the Japanese eat eels often even in winter. In a local magazine, it says that the Japanese also eat the eels or unagi on the day of the Ox in both cold and hot weather. And it is clear that eels are not limited to summer ones.

    Unaju vs Unadon

    Unadon (うな丼)

    Japanese often serve Unagi Kabayaki over rice. The grilled eel topping itself is the “Unagi no Kabayaki (鰻の蒲焼)“. There is very little difference between the two. Locals serve the Unadon is in a bowl and serve the Unajyu in a heavy box. You can only tell the difference between the bowl and the box in terms of the quantity of eel present. On average, you can expect to receive 1.5 times more eel in a serving of Unajyu, than in a serving of Unadon. There is no difference in the quality of each.

    Both are available as a normal-sized or special-sized portion. Unadon was created in the late Edo period of Japan, while Unajyu was not created until later, during the Meiji period. In Japan, they have introduced the use of the heavy box so that it could be delivered to customers while the meal inside stayed warm. If you put the same amount of eel into the box it looks a little scarce, so the Japanese introduced the larger-sized meal for the box version.

    Final Thoughts

    Unadon (うな丼)

    When people talk about Japan, unagi (eel) usually pops into people’s minds. Like sushi, Japan is very famous for its unagi, and usually, the image we have is a tender slice of eel with sweet sauce over a bowl of Japanese rice. However, Tokyo seems to have taken the simple unagi dish to a whole new level. There are other unagi dishes in Japan such as Unajyu and Hitsumabushi
