Unagi
Tokyo, Japan
Unagi is freshwater eel that is commonly prepared kabayaki-style: fillets are split, brushed with a sweet-savory tare and grilled, often several times, until the skin is lightly crisp and the flesh turns soft and rich. The sauce should add gloss and seasoning without burying the eel’s natural flavor. In Tokyo, unagi may be served over rice as unadon or in a lacquered box as unajū, with sansho pepper offered to sharpen the richness. The texture is tender and fatty rather than flaky like most fish.
Tokyo’s unagi culture is connected with long-established eel restaurants and the city’s Edo-style preference for grilling and saucing the fish. It is not an everyday cheap bowl in the way that many noodle dishes are, and specialist preparation can take time. Diners may order a set with soup and pickles, or choose a portion over rice. The dish also carries seasonal associations in Japan, but restaurants serve it throughout the year. For travelers, the key distinction is the eel’s preparation, not simply the word “eel” on a menu.
Why locals eat it
Unagi sits within Japan’s specialist restaurant culture, where the preparation of one ingredient can define an entire meal. Tokyo is particularly associated with Edo-style handling and grilling, while eel traditions exist across Japan in different forms. The dish’s reputation comes from technique: filleting, steaming or grilling practices vary, and tare is often treated as part of a shop’s character. Seasonal customs have helped keep unagi culturally visible, but it is more accurate to describe it as a traditional specialty with regional variation than as a food everyone eats regularly.
Local tip
Look for unadon or unajū if you want eel over rice, and ask whether the restaurant grills to order; specialist shops may take longer. Use a small amount of sansho pepper after tasting the eel plain, because its citrusy heat cuts through the fat. Check portion size before ordering—unagi sets can be richer and more filling than they appear.
