Isaki from Nagasaki, Japan

Isaki (grunt) is a highlight of seasonal fish from spring through summer. We source our Isaki straight from the northwestern tip of Kyushu, specifically, Nagasaki Prefecture, which ranks first in Japan for Isaki catch. Bred in Nagasaki’s favorable environment, Isaki is a white-fleshed fish known for its excellent texture and fat content, but that’s not all that comes from these waters. . .

In addition to Isaki, a variety of other fish can be found in Nagasaki’s waters. The region is renowned for having the richest diversity of fish in Japan. With a coastline that is about 12% of the country’s total, spanning 4,179 km, Nagasaki features many outlying islands, peninsulas, capes, bays, and inlets. The vast waters along this coastline are nourished by warm currents flowing northward from western Kyushu, cold waters from the Yellow Sea, and other coastal influences. Furthermore, the diverse topography, which includes around 1,500 islands and a complex seafloor, creates excellent fishing grounds.

The bounty of Nagasaki influences much of our menu. In addition to Isaki, we also bring in other fish caught in Nagasaki, including sea bream, horse mackerel, conger eel, red sea bream, and kuei (Japanese dolphinfish).

The story behind our sushi rice

Of course, rice is extremely important in Japanese cuisine, particularly because 70% of sushi is made with it. The month of May is integral to this, as it marks the rice planting season in Japan. The entire process of rice production takes one year and consists of several key steps: 1) seed selection (seed preparation), 2) seedling cultivation, 3) soil preparation, 4) rice planting, 5) rice growth, 6) harvesting, 7) drying, and 8) rice milling. These steps must be completed over the course of a year.

Selecting the right rice is crucial, as not all types are suitable for various uses, including sushi. The best rice for sushi is a short-grain japonica variety known for its firm and elastic grains. At Shiro’s, we use Haenuki rice from Great Rice, sourced from the largest and best farmer in the Tsuruoka area, Yamagata Prefecture. To maintain their exceptional quality, they use the organic Aigamo farming method and deliberately limit their yield to one-fourth of the typical harvest per unit area, achieving a level of quality that others simply cannot replicate.

“Haenuki” is a brand developed in Yamagata Prefecture and is known as the best rice for sushi. Haenuki is characterized by its strong grain tension and texture. Its grains do not easily crumble when mixed with vinegar, making it ideal for sushi. According to our chefs, “We choose Haenuki for our sushi rice because of its chewy texture, flavor, and sweetness.” Yes, Chef!
