Japanese tiger prawns, known as kuruma ebi, are considered one of Japan’s finest types of prawns, alongside Japanese spiny lobster. They are highly valued for their sweet flavor and firm, springy texture, and are used in a wide variety of dishes.
Among shrimp and prawns, kuruma ebi are particularly prized as a luxury ingredient. Their excellent flavor and versatility have made them a familiar feature of Japanese seafood cuisine.
Because kuruma ebi are such a highly valued seafood product, they were the first among shrimp and prawns in Japan for which aquaculture technology was successfully established.
Farming of kuruma ebi became increasingly active from around 1965. Alongside natural catches, aquaculture has helped make these prized prawns available as an important seafood product.
Kuruma ebi are actively caught in Oita Prefecture. The main areas mentioned for local catches are Usa City, Himeshima Village, and Kitsuki City.
These areas are part of Oita’s rich coastal environment, which supports a variety of seafood and contributes to the prefecture’s reputation as a destination for fresh marine products.
The main season for Oita’s kuruma ebi is from July through December. During these months, visitors have an opportunity to enjoy the prawns in a variety of preparations.
Freshness is especially important when enjoying kuruma ebi. The fresher the prawn, the more pronounced its natural sweetness and the more satisfying its distinctive springy texture.
Kuruma ebi can be enjoyed in several ways, from preparations that highlight its freshness to dishes that bring out its rich flavor through cooking.
One distinctive way to enjoy kuruma ebi is odorigui, in which the live prawn is peeled and eaten immediately as sashimi. This preparation emphasizes the freshness, natural sweetness, and lively texture of the prawn.
Kuruma ebi is also excellent as tempura. The prawns are coated in a light batter and deep-fried, creating a crisp exterior that contrasts with the tender, springy meat inside.
Salt-grilling is a simple preparation that allows the natural flavor of the prawn to stand out. The gentle seasoning enhances its sweetness without overpowering the seafood’s own taste.
Kuruma ebi can also be steamed with sake. This cooking method gives the prawns a delicate aroma while allowing their natural flavor and texture to remain central to the dish.
Kuruma ebi contain a particularly high amount of amino acids associated with sweetness compared with other types of shrimp and prawns. This is one of the reasons they have such a distinctive and appealing flavor.
The fresher the prawns are, the sweeter they taste. Their firm, springy texture is another important characteristic, providing a satisfying bite that makes them especially enjoyable as sashimi and in cooked dishes alike.
Oita’s kuruma ebi are a premium seafood specialty supported by both natural fishing and established aquaculture. Caught in areas including Usa, Himeshima, and Kitsuki, they are enjoyed from July through December in a variety of preparations.
Whether eaten as live prawn sashimi, tempura, salt-grilled prawns, or sake-steamed prawns, kuruma ebi offer a chance to appreciate the sweetness and firm texture of one of Japan’s most prized seafood ingredients.
