Isaza, also known as shirouo (ice goby), is a small fish belonging to the goby family. Even when fully grown, it reaches only about 5 centimeters in length. Caught in the Miyazu area of northern Kyoto Prefecture, it is a seasonal delicacy that signals the arrival of spring.
In early spring, isaza swim upstream to spawn and are caught using nets. For local residents, seeing fishermen wading into the rivers to catch these tiny fish is a familiar sign that spring has arrived.
Isaza is prized for its slippery-smooth texture and easy passage down the throat. One of the area’s best-known specialties is odorigui, a dish in which the small fish are eaten alive, allowing diners to experience their lively movement and distinctive texture.
Isaza is also delicious when gently cooked with beaten egg or mixed into rice. These simple preparations allow the fish’s delicate flavor to blend beautifully with the other ingredients.
