Nodoguro the Fatty White Fleshed Delicacy

Nodoguro, formally called akamutsu, is a prized white fleshed fish that represents the bounty of the Sea of Japan. Its name comes from the black interior of its throat, and its meltingly refined fat has captivated countless connoisseurs.

Highlights

Grilled with salt, the fat dripping from the skin and the fragrant aroma are irresistible. As sashimi, the white flesh delivers rich umami and a melting texture, and as nigiri sushi the harmony of fat and vinegared rice stands out. Large quantities are landed at Murakami City (Sanpoku and Iwafune), Niigata City, and Itoigawa City (Tsutsuishi), and the appeal is being able to eat it with the freshness only a source region offers. It also changes character by preparation, from simmered to lightly seared, another pleasure to explore.

What Kind of Fish Is Nodoguro?

Nodoguro's standard Japanese name is akamutsu. It is classified in the family Acropomatidae of the order Perciformes, wears a vivid red over its whole body, and has long been known by the popular name "nodoguro" — "black throat" — because the back of its mouth is black when opened. It is a warm-water fish distributed from the continental shelf to the continental slope of the Pacific, the Sea of Japan, and the East China Sea south of Hokkaido, living on sandy-muddy bottoms at depths of roughly 100 to 200 meters and growing on a diet of small fish, shrimp, and crabs. That life of feeding richly in deep water is what leads to its abundant fat. Taxonomically it is a white-fleshed fish, but the richness of its fat is such that it is called "the toro of white fish," giving it a depth quite unlike the image of a lean white fish.

The Nodoguro Fishery in Niigata

In Niigata Prefecture, nodoguro is caught by bottom trawl as well as by gochi net, longline, and gill net. July and August fall within the closed season for bottom trawling, so during that period longlining is the main method. Fish taken on a longline, hauled up one at a time, are said to suffer less damage to the body and to be superior in freshness. The main producing areas spread across the prefecture — Murakami City, Niigata City, Itoigawa City, Sado City, and the Chuetsu district — giving Niigata, long from north to south and facing the Sea of Japan, an unusually varied set of landing sites. Part of the fun of eating it at the source is that the fishing methods and the seasonal character differ a little from port to port.

Many Ways to Eat It, Savored with All Five Senses

As sashimi, fine flecks of fat scatter through the translucent white flesh, and the rich umami dubbed "the toro of white fish" slowly unwinds in the mouth. Grilled with salt, the very moment when the skin crackles, the fat drips, and fragrant steam rises is itself a feast. Simmered, the flesh flakes apart tenderly into a deep flavor where fat and broth mingle. At sushi restaurants in Niigata it is sometimes served as nigiri seared with the skin still on, letting you enjoy the balance of aroma, fat, and vinegared rice. Ordering a whole fish and working your way down to the head and collar is another pleasure unique to the source region.

Photography Tips and Choosing a Restaurant

The red body of the fish photographs well, but strong light easily creates glare, so shooting with soft light from an angle brings out the texture of the scales. For the salt-grilled fish, holding the camera at an angle slightly above the plate while the steam is still rising captures both the sheen of the skin and the rising steam in one frame. For sashimi, a dark-colored dish makes the translucence of the flesh stand out more than a white plate does. Because whether nodoguro is served depends on the day's purchasing, if you want to be sure of tasting it, it is reassuring to confirm when you reserve. At a diner attached to a market, you may encounter a dish that reflects that day's landings.

Enjoying the Seasons

In Niigata, the season is considered to be summer into autumn (around July to September), overlapping with the spawning period, and Niigata Prefecture's fisheries information also describes the fish as "in season all year, loaded with fat." During July and August, the closed season for bottom trawling, it is caught by longline, and fish from this period are said to be especially fresh. In peak season, nodoguro often appears on the menus of sushi shops and traditional restaurants.

Access and Basic Information

It can be enjoyed at markets around Niigata port and at sushi shops and traditional restaurants in the city. Access from Niigata Station is good, and choosing a shop that handles local fish leads you to a plate fresh from the catch. Diners attached to markets sometimes serve nodoguro dishes according to the landing of that day.

Practical Travel Notes

Because nodoguro is a premium fish, sushi and sashimi of it tend to be priced higher than other items, so checking whether you can order by the piece or plate helps manage your budget. Availability shifts with the season and the catch, so if you want to be sure of tasting it, asking ahead is reassuring. Dried and overnight dried fillets make good souvenirs and can be bought at markets and specialty shops.

A Quick Tip

First taste the fat of the fish itself grilled with salt, then compare textures with sashimi or sushi. The more ways you try it, the more you sense the depth of nodoguro. With the grilled version, savoring the fragrant skin along with the flesh brings out its appeal.

Souvenir and Takeaway Hints

Nodoguro (akamutsu) is a premium fish of the Sea of Japan, and its white flesh, carrying a refined layer of fat, has earned the nickname "the toro of white fish" — a flavor Niigata takes pride in. Grilled with salt, simmered, as sashimi, or as sushi, you can savor its melting richness. The season is autumn into winter. Processed products such as overnight-dried and mirin-dried fillets are available at fishmongers, souvenir shops, and by mail order, and frozen items that keep well make good gifts. Tasting a well-fattened nodoguro at a sushi restaurant or eatery in Niigata is highly recommended.
