What is Torokinme?

Fusenkinme (Red bream) is occasionally caught along with Splendid alfonsino (Kinmedai). Until recently, they were considered to be the same species. Kinmedai has elongated slit-like posterior nostrils, while Fusenkinme has oval-shaped posterior nostrils. Kinmedai can grow over 50 cm long, whereas Fusenkinme stops at 40 cm.

Fusenkinme is fattier than Kinmedai and is called Aburakinme or Torokinme by fishermen, in areas that distinguish between Fusenkinme and Kinmedai, there is a difference in market price, but it is rarely distributed and is consumed locally.

Torokinme does not refer to the belly part of Kinmedai but to Fusenkinme, a rare species of Kinmedai. Incidentally, three Kinmedai, Nanyokinme, and Fusenkinme species are distributed in Japan.

What is Torokarei?

A photo of Torokarei fillet — The appearance of Torokarei fillet

Consumers are inevitably confused by the word Toro. It isn’t easy to separate the word from a mere marketing term. Therefore, the market contains fish names with Toro as a prefix.

Torokarei (karei means flounder) is a trade name for a fish named after the toro of tuna, which has a rich, tender texture, and is an arrowtooth halibut (Aburakarei).

Aburakarei is distributed north of Choshi, the northern Sea of Japan, the Sea of Okhotsk, and the western Bering Sea. Aburakarei is a typical eating fish among flounder species, and unfortunately, it is considered the most tasteless and has low commercial value. Black halibut (Karasugare), a relatively tasty and inexpensive fish, has become expensive, so perhaps it is Aburakarei’s turn.

So a name that would sell was needed, so it became Torokarei.

In recent years, Aburakarei has been imported from the U.S. and other countries in large quantities of fillets processed for frying. It is inexpensive and its distribution is stable. Aburakarei is characterized by its meat containing so much fat that it melts when heated. Even when heated, the flesh remains tender, and it is often used overseas for frying as fish and chips. The most common type of engawa at conveyor-belt sushi restaurants is either Aburagarei or Karasugarei.

What is Largescale blackfish (Mejina) sushi?

a photo of Largescale blackfish (Mejina) — Largescale blackfish (Mejina) lives in rocks close to the shore and look for seaweed to eat. It creates an unique, delicious flavor come with a strong sea smell and it taste out a little bit firm with slightly sweet.

What is Largescale blackfish (Mejina)?

Largescale blackfish (Mejina) is distributed throughout Japan south of southern Hokkaido, Taiwan, and the East China Sea. Its bodies are oval and flattened, and its body color is blackish purple. It is diurnal and forms schools, moving to deeper waters offshore as it grows.

It can grow up to 60 cm in length, but most of those on the market are about 40 cm in length. In summer, it feeds on animal food such as small shrimps, and in winter, it prefers vegetable food such as seaweed and nori, which means that the season is winter, as the fish’s smell of the sea disappears and it becomes fatty during the winter.

The name of this species in the Kansai region is “Gure,” and it is a popular rock-fishing target. Its scientific name is Girella punctata Gray, 1835.

What does Largescale blackfish (Mejina) sushi taste like?

a photo of Mejina nigiri sushi — Largescale blackfish (Mejina) is mildly oily and a delicious white meat fish. There is a layer of umami under the skin so we’d advise to serve seared or yubiki with the skin-on.

Largescale blackfish (Mejina) looks like red seabream (Tai), but are related to Japanese sea bass (Suzuki). The Kuromejina (Girella leonina (Richardson,1846)) and Okinamejina (Girella mezina Jordan & Starks, 1907) are members of the Mejina family, but the Mejina has the best taste.

It can be served as sashimi, grilled, simmered, or even cooked in a pot. It is relatively easy to cook because it is well suited to cooking methods that use oil. If the gall bladder is accidentally broken, a strong odor can be passed around in the air, which can make it smell even worse. Therefore, it is important to avoid damaging the internal organs when cooking it.

It is inexpensive, but because it is not caught in large numbers, it is not always available at sushi restaurants. Its flesh is a beautiful pale pink color, which is hard to imagine from the black body surface.

In winter, it has a stronger taste than red seabream, with the fat coming in closer to the mouth and a stronger umami. In the summer, it can have a slightly peculiar aroma, so it is best to yubiki (parboil) or broil the fish before serving it as nigiri sushi.

What is Black scraper (Umazurahagi) sushi?

a photo of Black scraper Umazurahagi) — Black scraper is a filefish with high market value but the standing stock has been decreased in the past years due to the overexploiting and environmental fluctuations.

What is Black scraper (Umazurahagi)?

Black scraper (Umazurahagi) is distributed in the Sea of Japan from Hokkaido to Kyushu, the Pacific Ocean, the Yellow Sea, and the East China Sea from the Korean Peninsula to the coast of China. It is a familiar fish caught throughout Japan. Umazurahagi are called nagahagi (naga means long) because they are longer than Filefish (Kawahagi).

They are abundant at depths of around 10m, slightly offshore from Filefish. When young, around 10 cm in length, they migrate in schools, but as adults, they are often found alone. Adults gather in coastal areas to spawn from around May to July and dive to deeper water around November.

They are omnivores, feeding on benthic organisms such as seaweeds, crustaceans, polychaetes, and even jellyfish. Its scientific name is Thamnaconus modestus (Gunther,1877).

What does Black scraper (Umazurahagi) sushi taste like?

a photo of Umazurahagi nigiri sushi — Black scraper (Umazurahagi)’s white flesh has an elegant sweetness and a crunchy, pufferfish-like texture.

Black scraper (Umazurahagi) has a blurry appearance and does not look tasty, but once peeled, it reveals a clear white flesh similar to that of pufferfish.

The price of Umazurahagi is completely different between those caught in large quantities by bottom trawling fishing and those caught by pole and line fishing. Therefore, Ikejime or live fish are used for sushi toppings.

The liver, with its rich flavor, can be raw or seared and used in nigiri sushi to make an exceptional dish. Although it is looked down upon compared to Filefish and pufferfish, it is relatively affordable and highly regarded as a topping, and is not a substitute for Filefish at all.

However, the quantity of fish received at the Toyosu market and other markets is not stable. From that point of view, few restaurants offer nigiri sushi.

What is Marbled rockfish (Kasago) sushi?

a photo of Marbled rockfish (Kasago) — Small marbled rockfish (Kasago) are best deep-fried or simmered, while good-sized ones are also tasty as sashimi.

What is Marbled rockfish (Kasago)?

Marbled rockfish (Kasago) can be found anywhere along the coast from southern Hokkaido to the East China Sea. It lives in the shadows of reefs and blocks from the coast to depths of about 60m to 200m. A voracious carnivorous fish, it preys on crustaceans such as small shrimps, polychaetes such as ragworm, and small fish such as gobies.

Body color varies from dark brown, reddish, to blackish, and there is a great deal of variation depending on the environment in which they live. Those that inhabit deeper water are said to be redder, while those that inhabit shallower water are said to be darker. Another characteristic of this species is the irregular white patches on its back side.

Along with Mebaru and Ainame, it is a representative of rockfish (It is a fish that does not migrate far and has a small habitat). It is about 30 cm long. Its scientific name is Sebastiscus marmoratus (Cuvier, 1829).

Some species of marbled rockfish have poison lines on their pectoral fins and dorsal fins, so care should be taken when cooking them. Also, since they have many spines all over their body, when grabbing a live fish, put your thumb in their mouth and grasp their lower jaw.

It is generally considered a winter fish, but the season is spring. It is most fatty from January to April, and the black ones that inhabit the seashore are said to be tastier than the reddish marbled rockfish that inhabit offshore waters. It can be caught in all regions of the Japanese archipelago, which stretches from north to south, a light white fish that is easy to remove from the bone, so it is delicious regardless of the season. The larger ones are often made into sashimi or sushi, while the smaller ones are often eaten as boiled fish.

What is Marbled rockfish (Kasago) sushi taste like?

Marbled rockfish (Kasago) is treated as a high-end fish in the Toyosu market, but the supply is not consistent. In addition, its large head and low yield make it rare for restaurants to serve nigiri sushi and sashimi.

The elegant flavor of nigiri sushi and sashimi is, to put it mildly, unsatisfying. The best way to eat nigiri is to broil the skin and let the aroma come out. This will dissolve the gelatinous material under the skin, and the sweetness and umami of the fat can be felt gradually. It is also good to eat it with citrus fruits such as sudachi and salt.

What is Goldeye rockfish (Usumebaru) sushi?

a photo of Goldeye rockfish (Usumebaru) — Rockfish (Mebaru) is one of the primary fish found in the coastal waters of Japan. Characterized by their large bulged eyes, rockfish are highly prized species. There are a variety of types of rockfish (mebaru) in Japan.

What is Rockfish (Mebaru)?

Rockfish (Mebaru) are distributed over a relatively wide area from southern Hokkaido to Kyushu, the Korean Peninsula, and elsewhere. They inhabit rocky reefs at depths of 50 to 150 meters. The length of the fish is 20-25 cm.

There are several species of rockfish (Mebaru): Aka-mebaru (Sebastes inermis Cuvier,1829), Kuro-mebaru (Sebastes ventricosus Temminck and Schlegel,1843), and Shiro-mebaru (Sebastes cheni Barsukov,1988), which are generally called mebaru. However, the three species are so similar in appearance that it is difficult to distinguish them at a glance.

The fish is caught by pole-and-line and longline fishing starting around March, and becomes fat and oily by April when the water temperature begins to rise. Anglers are most likely to catch Kuro-mebaru. They are mainly eaten simmered or grilled.

However, the fish is poisonous in its dorsal fin, so it is important to be very careful when handling it. Because it is a very small amount of poison, it is a cause that is neglected, but there are times when serious symptoms appear.

What does Goldeye rockfish (Usumebaru) sushi taste like?

Sushi chefs use a species called Goldeye rockfish (Usumebaru), which is found in deeper waters offshore. The maximum length of the fish is 35 cm. The main production areas are Aomori and Yamagata prefectures.

Goldeye rockfish is a member of the scorpionfish family, but it is less fishy than scorpionfish and has a very light flavor with firm flesh. It has little fat and a light aftertaste, making it a good pairing with sushi rice. When served as nigiri sushi, it is also good to use Kobujime. Although the market availability is stable, it is traded at a high price.

What is Barfin flounder (Matsukawagarei) sushi?

a photo of Barfin flounder (Matsukawagarei) — Barfin flounder (Matsukawagarei) is large flat fish inhabiting cold sea water basins in the northern Pacific off Japan. It is suitable for aquaculture and resource enhancement in Hokkaido due to its high commercial value and growth rate at low temperatures.

What is Barfin flounder (Matsukawagarei)?

Barfin flounder (Matsukawagarei) is distributed along the Pacific coast north of Ibaraki Prefecture and in the Sea of Japan north of Toyama Prefecture, the southern Sea of Okhotsk, and the Kurile Islands. It inhabits sandy muddy areas at depths of up to 200 m, feeding mainly on crustaceans and small fishes. The maximum length of the body is 80 cm.

It is similar in appearance to the closely related Spotted halibut, but the Barfin flounder has banded black spots on its fins, while the Spotted halibut has circular ones. The name ” Matsukawagarei ” is said to come from its scales, which are hard and resemble the epidermis of a pine tree. Barfin flounder is now very rare in the wild, and most of the fish caught are released juveniles. This is based on the habit of flounder species to remain in the waters where they are released. The main production areas are Hokkaido, Aomori, and Iwate prefectures, and the season is winter. The scientific name is Verasper moseri Jordan & Gilbert, 1898.

What does Barfin flounder (Matsukawagarei) sushi taste like?

a photo of Barfin flounder (Matsukawa) nigiri sushi — The standard Japanese name is Matsukawa, not Matsukawagarei.

Barfin flounder (Matsukawagarei) tastes better in larger sizes, and the males are tastier than the females. Its flesh is firm, and when fresh, it tastes better when thinly sliced. The umami increases after about two days of maturing, as is the case with other flounders.

Barfin flounder, along with spotted halibut, is a high-end fish, and if asked which is more delicious, barfin flounder or spotted halibut, most people would probably say spotted halibut. However, the reason may be that they are not familiar with Barfin flounder. As proof of this, you will almost never see it at high-end sushi restaurants in Tokyo, but it is not that uncommon at high-end restaurants in Sapporo.

What is Spotted knifejaw (Ishigakidai) sushi?

a photo of Spotted knifejaw (Ishigakidai) — Spotted knifejaw (Ishigakidai) is distributed along the coasts of the Sea of Japan, the East China Sea, and the Pacific Ocean from the entire coast of Hokkaido to the southern coast of Kyushu, the Izu Islands, the Ogasawara Islands, Yaku Island, Okinawa Island, and Okinotori Island.

What is Spotted knifejaw (Ishigakidai)?

Spotted knifejaw (Ishigakidai) is distributed along the Pacific coast south of Ibaraki Prefecture and along the Sea of Japan south of Yamaguchi Prefecture to the South China Sea. It inhabits mainly rocky reefs. The length of the body reaches 90 cm.

The ecology and habits are similar to those of Barred knifejaw (Ishidai), but young fish are generally brownish with numerous blackish-brown stone wall (stone wall is ishigaki in Japanese) patterns scattered throughout the body. As the fish grows, the pattern becomes lighter, and in male adults it disappears completely. The season is summer.

Note that some of the larger Barred knifejaw and Spotted knifejaw (over 60 cm) may have Ciguatera poisoning. The scientific name is Oplegnathus punctatus (Temminck and Schlegel, 1844).

What does Spotted knifejaw (Ishigakidai) sushi taste like?

a photo of Spotted knifejaw (Ishigakidai) nigiri sushi — Spotted knifejaw (Ishigakidai) is a delicious white-fleshed fish very similar to Barred knifejaw with a tough and springy texture that makes it very chewy and gives it a light fragrance of the ocean when served as sashimi.

The meat of Spotted knifejaw (Ishigakidai) is firmer and tighter than that of Red seabream (Madai), and it is so chewy that it feels too hard to make sashimi if it has just died. Therefore, like puffer fish, usuzukuri (thinly sliced) is used for sashimi and sushi topping.

Spotted knifejaw has a more subtle scent of the sea than barred knifejaw. The color of chiai (dark red meat) is not a bright red, but rather a duller shade, but the meat is surprisingly fatty and delicious.

Nigiri sushi is also good with salt and kabosu. Its umami is thought to arise from eating sea urchins, shellfish and crustaceans. Both nigiri sushi and sashimi are rare in Tokyo, but common in Shikoku and Kyushu.

What is Silver croaker (Ishimochi) sushi?

a photo of Silver croaker (Ishimochi) — Because it loses its freshness quickly, the average supermarket is unlikely to find fresh eating silver croaker (Ishimochi or Shiroguchi). The high-moisture content of the silver croaker is said to make it an exquisite dish when grilled with salt.

What is Silver croaker (Ishimochi)?

Silver croaker (Ishimochi or Shiroguchi) is distributed in the Tohoku region and southwards, the East China Sea, the Indian Ocean, and the western Pacific Ocean. It is mainly found on sandy mud bottoms at depths of 20~140m. Its body color is shiny silvery white with somewhat indistinct black spots on the tops of its gill covers. The Japanese name Ishimochi (Ishimochi means having the stones) is derived from the presence of large calcareous otoliths within the skull bones. The length of the body is about 40 cm. The season is summer. Caught in large quantities in the East China Sea by bottom trawl fishing, it is mainly used as a raw material for high-grade fish paste. The scientific name is Pennahia argentata (Houttuyn,1782).

What does Silver croaker (Ishimochi) sushi taste like?

Silver croaker (Ishimochi) can be eaten raw if fresh, and it goes well with vinegared rice. Its clear white flesh has a firm texture, but it is somewhat watery, so it is best served as sujime or yubiki.

There are many delicious white fish, but in terms of individuality, Silver croaker may be the top level among sushi toppings. Conversely, I am once again impressed by the power of vinegared rice that catches the peculiarities of Silver croaker. In the Kanto region, it is a popular fish for salted grilled fish, and it takes on a completely different flavor when grilled.

What is Golden threadfin bream (Itoyoridai) sushi?

a photo of Golden threadfin bream (Itoyoridai) — Golden threadfin bream is one of the most important species of commercial fisheries in the East China Sea and northern South China Sea.

What is Golden threadfin bream (Itoyoridai)?

Golden threadfin bream (Itoyoridai) is distributed in Chiba Prefecture and southward except Ryukyu Islands, Korean Peninsula, East China Sea, South China Sea, Philippines, and Northern Australia. It has a low, slender body shape, is generally reddish yellow with 6~8 longitudinal yellow stripes on the body, and the upper lobe of the tail fin is elongated in a thread-like shape. It lives on muddy bottoms at depths of 40~100m and are 40~50cm long. Its season is from fall to winter.

The yellow stripes on its body are beautiful and do not fade after being caught, so it is often used for celebrations and festivals. It can be found in the market all year round, but the catch is not so large that it is in short supply. It is more highly prized in the Kansai region than in the Kanto region, where it is treated as a luxury fish. It is not a member of the bream family and used to be called Golden threadfin (Itoyori) without bream.

A closely related species, yellowbelly threadfin bream, is very similar, but the Toyosu market does not distinguish between the two and distributes them under the name Itoyori. There is almost no difference in taste. If anything, Yellowbelly threadfin bream (Nemipterus bathybius Snyder, 1911) is a bit softer than Golden threadfin bream (Nemipterus virgatus (Houttuyn, 1782)). Itoyori surimi is used to make Kamaboko (fish cake). It is one of the most important species of commercial fisheries.

What does Golden threadfin bream (Itoyoridai) sushi taste like?

a photo of Itoyoridai nigiri sushi — Golden threadfin bream (Itoyoridai) can definitely be eaten as sashimi, kobujime nigiri, sujime nigiri, or steamed with sake.

Golden threadfin bream (Itoyoridai) is used widely in French and Italian cuisine because it has a light, natural flavor and does not shrink when heated. However, it has high water content, so its flesh is a bit softer when made into sashimi.

Golden threadfin bream has umami not only in its meat but also in its skin, so immersed it in boiling water quickly to retain its umami flavor and give it a beautiful appearance.

And then Kobujime makes nigiri sushi with a mild and elegant flavor. The fat between the skin and the flesh contains umami, so it is sometimes seared to give it a savory aroma.

What is Red cornetfish (Akayagara) sushi?

a photo of Aka-yagara — Red cornetfish (Akayagara) was one of the underutilized fish, but will soon be promoted to a luxury fish.

What is Red cornetfish (Akayagara)?

Red cornetfish (Akayagara) is distributed mainly in warm seas around the world, from the seas around Japan south of central Honshu to the Indian, Pacific, and Atlantic Oceans. It inhabits depths shallower than 200 meters. They swim in small groups in rock and coral reefs’ upper layers. Adults are reddish brown, with each fin and belly side slightly paler and sticky without scales. The maximum length of the body is up to 2 m, one-third of which is the head, and the area from the tip of the mouth to the eye is long and tubular.

What does Red cornetfish (Akayagara) sushi taste like?

a photo of Aka-yagara sushi — If you find red cornetfish (Akayagara) at a sushi restaurant, you must try it.

Only Red cornetfish (Fistularia petimba Lacepède, 1803) and Bluespotted cornetfish (Fistularia commersonii Rüppell, 1838) are edible in the waters around Japan. Red cornetfish is more frequently caught. Despite its odd appearance, Red cornetfish is known as a tasty fish and is in season in the summer when few fish are in season.

The taste is mild and light, the meat is firmer than many other white-fleshed fish. It does not become hard even after being heated and is delicious even when steamed. It is so refined and flavorful that it is served as sashimi at Ryotei (Japanese-style restaurants), and is naturally delicious as nigiri sushi. Considering the yield rate, it can be said to be a super-premium fish.

What is Shirakawa?

Out of the five types of Amadai that live in Japan, Aka-amadai, Shiro-amadai and Ki-amadai are the three types offered in the markets.

The main characteristics of Aka-amadai are its overall red body, the bright yellow color under the eyes and how part of its fin is a shiny cobalt blue color. Aka-amadai is called “Guji” in the Kansai region and is a vital part of Kyoto cuisine. Ki-amadai has the same silhouette and size as Aka-amadai, but the Ki-amadai has more yellow color in its face and tail fin. They tend to prefer sandy seafloors at depths of 30 to 300 m and live deeper than any other type of Amadai. True to its name, Shiro-amadai is a white color (Shiro means ‘white’) so is also called Shirakawa (which means ‘white skin’).

Shirakawa is considered to be the finest of the Amadai and can cost more than US $100 per kilogram. Aka-amadai costs around US $40 per kilogram. Shirakawa always ranks in the top three fish for market price. Shirakawa has more elasticity than the other two and has rich fat, making it perfect as sashimi or a sushi topping. The umami is so strong that even when served raw, the customer sometimes thinks it’s been prepared using kobujime. The fat between the meat and the skin is sweet and the skin is delicious in its own right, so it can even be eaten as sashimi with the skin left on. The famous production sites include Tsushima in Nagasaki Prefecture and Yawatahama in Ehime Prefecture. They are in season from autumn to winter. However, they say in a catch of 1,000 Amadai, you can only get one Shirakawa, so it is a rare item you won’t often see, even in a high-end sushi restaurant.

What is Izumidai?

When you see “tai” on the menu at a conveyor belt sushi restaurant, it’s very likely that is not “madai” (Red sea bream). It’s a competitive industry where these conveyor belt restaurants have no problem using a variety of imitation or replacement fish if it means they can cut costs. In any case, the purpose for using different types of fish without even considering farmed cheap madai, is to further reduce costs.

First on the list is Nile tilapia. This fish was introduced from Egypt to rivers throughout the world as food in 1962. While it was farmed in large quantities in Japan, especially in Kagoshima, from the 1990s, production rapidly declined with the stagnant prices of farmed madai. However, they are extremely fertile and proliferate naturally, and started living in the thermal regions and the rivers where warm wastewater flow throughout Japan.

The commonly used names for this is “izumidai” or “chikadai”. While izumidai (Nile tilapia) is a freshwater fish, it was likely named after “tai” (sea bream) because of the similarities in appearance. In Taiwan, it is considered to be so similar in appearance and taste, that it is called “Taiwanese sea bream”. It is a popular fish for consumption on a global scale with high production and distribution volume.

However, even though has “sea bream” in the name, it is not actually related to the sea bream at all.

As an aside, at least 90% of the tilapia found in the U.S. is imported. Most of those imports come from China. It’s often said that they are raised on a large volume of antibiotics and pesticides, and they are kept fresh using high amounts of chemicals. It’s best to avoid eating it if possible. The tagline they give it is “Sushi grade tilapia is a high quality, firm fish with a mild, clean taste perfect for sashimi and sushi applications” You’ll be hard-pressed to even find kaiten sushi restaurants using this in Japan. In addition, it would never be used at restaurants that describe themselves as Edomae Sushi.

What is Engawa?

Engawa has both a unique, crunchy texture and delightful fat distribution and is said to be the most delicious part of hirame.

But what exactly is engawa?

a photo of Engawa nigiri — Engawa is not the name of a fish, but a generic term for a specific part of a fish.

Engawa is the generally used name for the meat muscle that moves the soft ray of the dorsal and ventral fins of flatfish (such as Hirame and Makogarei). Most people in Japan think of the hirame version when they hear the word ‘engawa’.

To go into a more advanced level of detail, there are three types of muscles that move the dorsal and ventral fins in fish: the erector spinae, the depressor and the scalene muscles. These muscles are well-developed in fish that move their dorsal and ventral fins often, like flatfish and flounder. Actually, not all three of these types are always consumed. If we look at the way hirame and makogarei are cut for preparation, the slanted muscle is taken to be used for engawa while the erector spinae and depressor are left, affixed to the fin ray, etc. In other words, to be exact, engawa is the slanted muscle of the dorsal and ventral fins.

The unique, crunchy texture comes from the high content of collagen, which is a scleroprotein. “Kakushi boucho” is used to make the crunch pleasant and is one of the skills a sushi chef must perfect. The delicious flavor is related to the high amount of fat compared to body meat. There is also a sense of elegant sweetness. Only four pieces of engawa can be taken from a single flatfish, so it makes sense that foodies love it.

The name “engawa” comes from its resemblance to the unique veranda structure of Japanese-style homes. This veranda is called “engawa” in Japanese.

Incidentally, substitutions have become common at kaiten sushi (conveyor belt sushi) restaurants, and the topping is especially popular among women lately. So the question is, how is it possible to eat this valuable topping that is only rarely available at expensive sushi restaurants, so cheaply at kaiten sushi? Actually, Greenland halibut engawa and Kamchatka flounder engawa are used as substitutes to hirame engawa. The proof of this is in a menu that lists only “engawa” and not “hirame engawa”.

When does Kinmedai taste the best?

No one is more sensitive to the changing of the seasons than sushi lovers. This must be because the taste of sushi toppings is directly tied to the seasons. There are terms to describe this such as Hashiri (early season), Sakari (in-season) and Nagori (late season), and using these words to understand what state the sushi topping is it allows you to grasp and enjoy the various different flavors. There is nothing that says a sushi topping is less delicious because it has a lower fat content.

For example, everyone wants to get in there and be the first to eat early season toppings. It’s obvious that these would all be toppings with low fat content. But early-season toppings have a liveliness that you can’t find in other foods, and some believe that eating these types of food will give you new vitality.

Once a fish is in peak-season, we eat it as sushi. This is because the fish has grown as it approaches breeding season, gradually gaining more fat, and at this stage in its development it has a richer flavor.

And the ‘holdover’ perhaps means that since the season is about to end, we need to get our fill now. While we may feel a bit sad that the season is ending, we can look forward to it coming around again the next year.

On the other hand, there are sushi toppings that don’t seem to fit into the seasons, although the seasonal dishes are one of the important reasons that Japanese food was registered under UNESCO World Heritage.

Those are deep sea fish such as Largehead hairtail, Japanese bluefish, Pollack and Splendid alfonsino.

Deep sea fish live at least 200 m below the surface of the ocean. For example, Splendid alfonsino lives at a depth of between 100 to 800 m deep, so it would generally be thought of as in-season in the winter when it has the highest fat content. However, except just before and after spawning season, the flavor of the Splendid alfonsino doesn’t change much throughout the year. Therefore, even high-end sushi restaurants always keep it in the topping case and it’s a popular choice.

Therefore, Splendid alfonsino is never actually “in-season”.

Since very little light reaches the deep sea, the water temperature remains more or less constant. In other words, there aren’t really seasonal (temperature) changes. The concept of season may not exist there.

Even so, you can think of it as especially delicious in the winter between December and February, when it has a higher fat content. Otherwise you might start to think of it as a fish that is “in-season” all year round, like salmon, and that just doesn’t feel quite as splendid.
