Unagi or Anago 7 Delicious Differences You Need to Know

What Is “Unagi”?

Unagi is the Japanese word commonly used for freshwater eel, particularly the Japanese eel (Anguilla japonica). It is a popular ingredient in Japanese cuisine and is especially well known for its rich flavor and soft, fatty texture.

Unagi is commonly prepared by grilling the eel and coating it with a sweet and savory sauce known as tare.

Popular preparations include:

• Unadon – grilled eel served over rice

• Unajū – grilled eel served in a lacquered box with rice

• Unagi sushi – grilled eel served with sushi rice

• Kabayaki – eel that is filleted, skewered, grilled, and glazed

Taste and Texture

Unagi tends to be rich, fatty, tender, and savory. The grilling process gives it a slightly smoky flavor, while the tare sauce adds sweetness and umami.

Its soft texture makes it quite different from many other types of sushi fish.

For example:

“I ordered unagi because I like rich, grilled seafood.”

Short History and Usage Note

Unagi has been eaten in Japan for centuries. It became especially associated with summer eating traditions, and Dōyō no Ushi no Hi, a day connected with the ox in the traditional calendar, is commonly associated with eating unagi.

Unagi is also an important part of Japanese restaurant cuisine and appears in both traditional dishes and modern sushi menus.

What Is “Anago”?

Anago is the Japanese term commonly used for conger eel, a saltwater eel belonging to the conger eel family.

Unlike unagi, which is associated with freshwater habitats, anago lives in the ocean.

Anago is frequently used in sushi and other Japanese dishes. It is often prepared in a way that produces a softer, lighter result than grilled unagi.

Taste and Texture

Anago generally has a lighter, softer, and more delicate flavor than unagi. It also tends to be less fatty.

A common preparation involves simmering or braising the eel until it becomes tender, followed by the addition of a sweet sauce.

For example:

“I prefer anago because it has a lighter flavor than unagi.”

Regional Notes

Anago is strongly associated with Japanese coastal cuisine and is especially well known in sushi restaurants.

Different regions and restaurants may prepare anago differently, so the exact texture and flavor can vary.

The term anago is normally used specifically for conger eel rather than freshwater eel.

Fun Facts or History

1. Unagi Has a Famous Summer Tradition

Eating unagi during summer is a long-standing Japanese tradition. The custom is particularly associated with Dōyō no Ushi no Hi and is often connected with the idea of eating nutritious foods during hot weather.

2. Eel Has a Complex Life Cycle

Freshwater eels such as Japanese eel are catadromous, meaning they spend much of their lives in freshwater but migrate to the ocean to reproduce. This unusual life cycle is one reason eel biology has fascinated scientists for generations.
