Section 1: What Is “Unagi”?
Unagi refers to freshwater eel, a staple ingredient in Japanese cooking. It’s especially popular in grilled dishes and is considered both a delicacy and a source of energy.
Meaning and Usage
The word unagi specifically refers to eel that lives in freshwater environments, such as rivers and lakes. In Japanese cuisine, it is almost always grilled and glazed with a sweet soy-based sauce known as tare.
You’ll commonly find unagi in dishes like:
- Unagi don (eel rice bowl)
- Unagi sushi (nigiri or rolls)
Where It’s Used
Unagi is widely used in Japan, particularly during the hot summer months. There’s even a traditional day called Doyo no Ushi no Hi, when people eat unagi to boost stamina.
Examples in Sentences

Anago refers to saltwater eel, typically found in coastal regions and oceans. While it’s also used in Japanese cuisine, it has a very different flavor and preparation style compared to unagi.
