Anago: Japan's Saltwater Eel

Softer and lighter than its freshwater cousin, this sea eel melts on sushi rice and fills tempura with fluffy flesh.

Quick answer: Anago is the Japanese name for conger or sea eel, a saltwater fish with soft, mild, delicate flesh that is lighter and less fatty than freshwater unagi. It is usually simmered or grilled and brushed with a sweet soy glaze for sushi, or fried as tempura. Anago-meshi, a rice bowl topped with grilled sea eel, is a famous specialty of Miyajima in Hiroshima Prefecture.

Anago and Unagi Are Not the Same

Visitors often confuse anago with unagi, the freshwater eel served over rice in summer. Both are long, slender fish, but they belong to different families and live in different habitats. Anago lives in the sea and sandy coastal bottoms, while unagi spends much of its life in rivers and lakes.

The flavor and texture differ as well. Unagi is rich and fatty with a firm bite, while anago is lighter, softer and more delicate. Anago tends to be fluffy and almost melting when cooked properly, with a gentle sweetness. Many people find it easier to eat in larger quantities. For this reason, anago can be a good choice for diners who find unagi too heavy.

On a sushi menu, the two usually appear separately. Anago is typically brushed with a sweet, thick sauce called tsume, a reduction made from the simmering liquid. Unagi gets a heavier glaze. If you are unsure, ask the chef which one you are ordering and how it is prepared. Tsume is made by simmering the cooking liquid down until it is thick and sweet.

How Anago Is Prepared

For sushi, the fish is opened along the back, cleaned and simmered gently in a broth of soy sauce, sugar and mirin, sometimes with sake. The simmering makes it tender. After cooking, it is left to rest and then sliced and placed on vinegared rice. A light brush of sauce finishes it.

Another method is to grill the fish over charcoal, often after basting it with sauce. The grilled version has a smoky aroma and a slightly crisp surface. In some places, anago is served in a bowl over rice, with the fish pieces laid out neatly. Grilled anago is often served on its own or over rice.

Tempura is another popular option. The fish is coated in a light batter and fried, producing a crisp outside and a soft interior. It pairs well with a small dish of salt or a dipping sauce. Each method highlights a different quality of the fish. A light dusting of salt shows off the fluffy flesh.

Edomae Sushi and Tokyo Bay

Anago is an essential part of Edomae sushi, the style associated with old Tokyo. In Edo-period Tokyo Bay, fishermen caught plentiful sea eel, and sushi cooks developed ways to prepare it. The simmering and glazing method is a hallmark of the tradition. Edomae simply means in front of Edo, a reference to the bay.

The summer months are traditionally associated with anago. The fish is considered to have a delicate flavor at that time, and many sushi restaurants feature it as a seasonal item. However, availability and quality vary by catch location and year, so check with the restaurant or market. Summer anago is often described as light and clean in flavor.

At many sushi counters, anago is one of the last pieces served in a set, as its soft sweetness provides a gentle finish. If you order omakase, you may see it near the end of the meal. This ordering is a convention, not a rule, and chefs have their own approach.

Miyajima and Anago-Meshi

Miyajima, an island in Hiroshima Bay also known as Itsukushima, is famous for its floating torii gate and for anago-meshi. The dish consists of grilled or simmered anago laid over rice seasoned with sauce, sometimes in a lacquered box or a bowl. Local restaurants and shops serve it throughout the island.

A well-known station bento based on anago-meshi has been sold near the ferry terminal area for many years. The bento is a favorite among travelers heading to the island, and it demonstrates how a local specialty can become a travel icon. Availability changes, so check current details. Local shops also sell boxed versions and individual servings.

To reach Miyajima, travelers take a train to Miyajimaguchi Station from Hiroshima and then board a short ferry. The ferry ride offers views of the torii gate. Plan time to explore the shrine, walk the shopping street and eat. Check official sources for ferry and train schedules. Ferries run frequently, and the crossing is short.

Where to Eat Anago

Sushi restaurants of all levels serve anago, from conveyor belt chains to high-end counters. Tempura restaurants also commonly offer it as part of a set. Anago bowls appear at lunch spots in coastal cities, especially around Tokyo Bay, Hiroshima and the Seto Inland Sea. Prices vary widely depending on the type of establishment.

Fish markets and department store food halls sell prepared anago, including grilled fillets and sushi packs. Seasonal bento boxes frequently feature it. If you want a souvenir, look for vacuum-packed grilled anago, which keeps for a limited time. Check labels and storage guidance. Look for products that show the date of preparation.

Ask restaurants whether the anago is local. Some places source from specific regions and will proudly say so. Many provide English menus or picture menus, which help with ordering. A polite question or a gesture is usually welcomed. Waiters are often glad to explain how the fish is prepared.

Eating Tips and Etiquette

When eating anago nigiri, you can use hands or chopsticks. The sauce is already applied, so avoid dipping it in soy sauce unless the chef suggests it. Doing so may overpower the careful seasoning. Pick it up gently and eat it in one or two bites. Take a moment to enjoy the aroma before the first bite.

For tempura, use the salt or sauce provided and eat promptly while it is crisp. For rice bowls, mix a bit of fish and rice in each bite. A small amount of sansho pepper, if offered, adds a citrus note. Eat the pieces in the order they arrive.

Be mindful of bones. Anago has small bones, which are usually softened or cut during preparation, but some may remain. Eat attentively, especially if serving children. Drink tea between bites to refresh the palate. Chew slowly and place any bones on the side.

Seasons, Pairings and Mistakes

Summer is the classic season, but anago is available much of the year. Light sake, beer and green tea pair nicely with the fish. Pickles and clear soup are common accompaniments. In summer, cold dishes such as cucumber salad provide contrast. Winter anago can be good too, especially when simmered.

A common mistake is assuming anago tastes like unagi. It is milder, so expect a softer, lighter flavor. Another is leaving the fish sitting, which can make the texture lose its fluffy quality. Eat soon after it is served. Think of it as closer to a soft white fish than to a rich eel.

If you enjoy trying seafood varieties, ask the chef for recommendations. Anago is a good choice for those who want a gentle introduction to cooked fish on sushi. It balances the sharper tastes of raw fish and makes the meal more varied. Ask for a mixed plate to taste both anago and other items.
