Yellowtail, sold in Japan as hamachi or buri, is the country’s top farmed finfish export by value at USD 137 million (SeafoodSource, 2020).
On a sushi menu it shows up raw and farmed, with a buttery, mildly sweet taste that lands between lean white fish and fatty tuna. The fish is Japanese amberjack (Seriola quinqueradiata), a jack in the family Carangidae. Not a tuna, whatever the menu implies.
Sushi bars serve it as nigiri, sashimi, maki and crudo, and plenty of people try it right after salmon and tuna.
The name on a menu still says little about species, because “yellowtail” covers more than one fish.
What Is Hamachi Sushi?
Order hamachi at a sushi bar and you get raw, mostly farmed young yellowtail laid over seasoned rice. FishBase files the fish under Carangidae, the jack and pompano family.
Sushi at its core is vinegared rice with a topping, and hamachi is one of the most ordered toppings on a sushi bar menu. Anyone new to the format can start with the basics of sushi and come back here for the details.
It isn’t tuna, though some restaurant glossaries still say “yellowtail tuna”, and it isn’t a white fish either, since the flesh is medium in color with a darker strip down the center. Kampachi and hiramasa are separate Seriola species.
The flavor is mild, which is why it works as a first step beyond salmon and tuna.
Hamachi, Buri and Yellowtail: Are They the Same Fish?
They’re all Seriola quinqueradiata. Hamachi, inada and buri are names for the same fish at different sizes and ages, and the name also changes by region.
| Approx. length | Kanto name | Kansai name |
|---|---|---|
| Up to 35 to 40 cm | Wakashi | Tsubasu |
| 35 to 60 cm | Inada | Hamachi |
| 60 to 80 cm | Warasa | Mejiro |
| Over 80 cm | Buri | Buri |
Those lengths come from Sushi Walker’s dictionary. Other sources draw the lines elsewhere.
FAO’s capture-based aquaculture review sorts cultured fish by weight, so under 5 kg is hamachi and anything heavier is cultured buri. Sushi Walker goes by length instead (Kansai hamachi at 40 to 60 cm, buri above 80 cm in every region), and Tsuji Culinary Institute’s fish-handling guide puts Kanto inada near 40 cm and buri at 70 to 80 cm.
The cutoffs shift because the names grew out of trading practice, not a fixed standard. Sushi Walker adds that wholesalers often call any farmed fish hamachi and any wild fish buri, whatever its size.
Retail packaging adds a twist. SeafoodSource reports that vacuum packs of farmed fish are usually labeled buri, while the same product is sold as hamachi at retail.
The English word is looser still. FDA’s seafood hazards guidance (Appendix 6) maps the Japanese name hamachi to the U.S. market name yellowtail.
FDA’s archived Regulatory Fish Encyclopedia, captured in 2009, ties that same market name to Seriola lalandi. SeafoodSource notes that farms in Hawaii and Mexico sell other Seriola species in the U.S. as yellowtail.
So “yellowtail” on a menu narrows nothing. Read it as a hint, not a species ID.
What Does Hamachi Taste Like Compared With Other Sushi Fish?
Mild and buttery, with a faint sweetness and a firm bite. There is little of the briny edge some sushi fish carry.
Fat drives that profile, and the farmed fish carry a lot more of it. FAO’s fish composition tables list 12.3% fat for farmed Japanese amberjack against 2.3% for wild fish, and note that the lowest farmed readings came from young fish.
The wild figure is a snapshot, not a rule. Winter kanburi, the fatty wild yellowtail landed in the cold months, runs richer than a summer catch.
MasterClass points to the mild taste and firm, buttery texture as the reason novices take to it.
Hamachi vs salmon and tuna
Next to salmon, hamachi reads milder and firmer, with a cleaner finish.
Tuna is the other benchmark. Hamachi belly comes closest to the richness of the fatty tuna cut called toro, while the loin stays leaner.
Hamachi vs kampachi and hiramasa
All three are farmed Seriola species. Texture is where they separate.
| Fish | Taste and texture | Price vs hamachi | 2018 farmed volume |
|---|---|---|---|
| Hamachi (Seriola quinqueradiata) | Buttery, fatty | Reference point, cheaper | About 100,000 MT (all farmed yellowtail) |
| Kampachi (Seriola dumerili) | Springier, cleaner | Higher | 34,000 MT |
| Hiramasa (Seriola lalandi) | Close to kampachi | Higher, tracks kampachi | 5,000 MT |
Figures and comparisons are from SeafoodSource’s March 2020 report on the Seafood Show Osaka.
One naming trap sits on top of that. In July 2023, FDA added “Kanpachi (Ocean-Farmed)” to The Seafood List as a market name for Seriola rivoliana, while FAO lists Japanese kampachi as Seriola dumerili.
A kanpachi on a U.S. menu can therefore be a different species from the Japanese fish. Hamachi is the richer pick, and kampachi suits anyone who wants a leaner, springier bite.
How Is Hamachi Served in Sushi?
Mostly raw, as nigiri, sashimi, maki rolls and crudo. Grilled collar (kama) covers the cooked side of the menu.
Nigiri and sashimi
Nigiri is the standard format. The fish sits on shari, the seasoned rice, with a dab of wasabi between them, which is what makes nigiri its own style. MasterClass notes that a single slice of jalapeno often tops hamachi nigiri.
Sashimi is the same slice without rice, so the fish carries the whole bite.
Hamachi nigiri also turns up in chef-led omakase menus, where the sushi chef sets the order.
At the counter you’ll usually get shoyu (soy sauce) for a light dip and gari, the pickled ginger, between pieces. Nigiri already has its wasabi. Belly and crudo tend to arrive with ponzu or citrus instead.
Belly and collar (kama)
The loin is the leaner, firmer slice behind most nigiri and sashimi. Belly has higher fat, so it comes out softer and richer. The collar, or kama, is the cut right behind the head and gills, and it is usually cooked.
SushiFAQ notes that flavor and texture shift by cut because fat content differs.
SeafoodSource describes buri-kama as grilled yellowtail collar. That puts kama on the cooked side of the menu.
Rolls and crudo
Maki rolls usually pair hamachi with scallion for crunch (MasterClass), and some add avocado.
Crudo is the Western take, with thin raw slices dressed in citrus or ponzu. Rice bowls (donburi) and carpaccio-style plates round out the raw options.
Is Hamachi Sushi Healthy?
Mostly yes. Raw hamachi is a high-protein fish with a solid omega-3 load, and the rice, sauces and cut decide how heavy the meal gets.
Per 100 g of raw fish, USDA FoodData Central (yellowtail, mixed species) lists 146 kcal and 23.1 g protein. Sushi Walker puts the omega-3s at about 1.7 g DHA and 0.32 g EPA.
USDA averages mixed yellowtail species, so its energy and fat values sit below what farmed Japanese hamachi shows in the fat figures cited earlier. Expect farmed belly cuts to land higher.
Sushi Walker also lists B vitamins and vitamin D. Kikkoman’s cookbook glossary names fat level as the one caveat.
On the plate, the cut matters most, since belly carries more fat than loin and the energy rises with it. Shari adds the carbohydrate the fish lacks. Raw yellowtail is low in sodium per USDA, so most of the sodium comes from the shoyu. Rolls and sauces pile extra energy on top of plain nigiri or sashimi.
Plain sashimi keeps the numbers closest to the fish itself. For how rice, rolls and sauces change the picture across a whole menu, see this look at whether sushi counts as a healthy meal.
Is Hamachi Sushi Safe to Eat Raw?
For most healthy adults, yes, when the fish was frozen to FDA parameters or comes with documented farm and feed controls. For pregnancy, no.
Parasites and freezing
FDA’s Fish and Fishery Products Hazards and Controls Guidance names several freezing routes that kill parasites in fish meant to be eaten raw. Any one of these qualifies:
- -4 F (-20 C) or below for 7 days total
- -31 F (-35 C) or below until solid, then held at -31 F for 15 hours
- -31 F or below until solid, then held at -4 F for 24 hours
The Food Code recommends those conditions to retailers. Tapeworms freeze out more easily than roundworms, so time and temperature both matter, and roundworms such as Anisakis are why parasites in sushi get so much attention.
Farmed does not automatically mean parasite-free. FDA treats fish raised on pelleted feed as free of that hazard, and flags farmed fish fed processing waste, fresh fish or plankton as a possible one.
Japanese farms are not uniform on feed. A SeafoodSource report from 2009, based on a visit to an Ehime farm, found raw fish still preferred over pellets for the larger yellowtail.
The U.S. Food Code lets operators skip freezing for some farmed fish only with a written supplier statement on how the fish were raised and fed. Ask for that statement, or for the freezing record.
If you’re buying a fillet to serve raw at home, look for springy flesh that returns to shape after a light press, and for brightly colored blood portions. Kikkoman’s cookbook glossary gives both tests, plus refrigeration and quick use once the fillet is home.
Mercury
NRDC’s Safe Sushi guide lists hamachi, buri, inada and kanpachi among fish to eat in moderation, or avoid when pregnant. A footnote admits that mercury data specific to these fish were not available, so proxy data stood in.
The measured numbers are thin too. The mercury survey tables from Japan’s Ministry of Health, Labour and Welfare, built from prefectural tests in 2000 and 2001, list inada, the same species at hamachi size in eastern Japan, at a mean of 0.061 mg/kg total mercury across 6 fish, with a maximum of 0.187 mg/kg.
Six fish is a small sample, and neither source tests farmed hamachi by name. The defensible read is no high-mercury signal and no strong dataset, so occasional portions fit better than daily ones.
Who should skip raw hamachi
Pregnancy is the clearest case. FDA’s foodsafety.gov guidance says raw seafood may carry parasites or Listeria and tells pregnant women to avoid sushi.
Consumer Reports, citing the CDC, also lists children under 5 among the groups who should avoid raw fish. And when the supply is unverified, with no freezing record or feed statement, order the fish cooked, since heating that kills bacterial pathogens also kills parasites (FDA).
Parents deciding for a child’s plate can read whether kids can eat sushi. Cooked hamachi, such as grilled kama, sidesteps the raw-fish rules above.
Where Does Hamachi Come From, and What Does It Cost?
Hamachi on a sushi menu is usually farmed in southern Japan. SeafoodSource’s market reporting says the yellowtail used for sushi and sashimi in Japan and abroad is usually farmed, while wild kanburi stays mainly a seasonal domestic item.
Farmed vs wild hamachi
Farmed hamachi is sold year-round with steady quality, because feed and harvest size are managed (Sushi Walker). SeafoodSource adds that exported yellowtail is almost exclusively farmed.
Wild kanburi is a winter catch eaten mostly in Japan. SeafoodSource says farm-raised yellowtail carry plenty of fat but taste less oily and lack the springiness of young wild fish.
Sources split on how fatty farmed hamachi really is. A PBS Food recipe writer says most hamachi sold in the U.S. carries the fat of Japanese buri, with hamachi in Japan leaner.
Sushi Walker describes Japanese hamachi as moderate in fat with a clean flavor. Fat is a farm decision.
Rumi Japan labels yellowtail fed a green tea catechin pellet as “Rumi Original Hamachi”. Azuma-Cho Fishery Cooperative in Kagoshima standardizes feed and logs daily growth data for its BURI-OH brand (Government of Japan, 2021).
Production and regions
Kagoshima, Ehime and Oita are the top prefectures, per the Ministry of Agriculture, Forestry and Fisheries 2016 yearbook as reported by SeafoodSource. The species is sensitive to cold, so net pens sit in warm water around Kyushu, Shikoku and the Seto Inland Sea. Azuma-Cho Fishery Cooperative is the largest producer.
The supply constraint is seed stock. Most commercial farms still stock wild-caught juveniles called mojako (Global Seafood Alliance), and Japan caps the annual mojako harvest at 27 million fish for all Seriola species combined. That is why the Fisheries Agency’s 2030 goal of 240,000 MT, up from under 140,000 MT, depends on closed-cycle breeding (SeafoodSource).
As of June 2026, Minato News reports that the 2026 wild juvenile catch fell significantly from recent years. It flags possible supply shortages from late 2027 and slower net-pen growth linked to rising sea temperatures.
Price and sustainability
Wholesale, hamachi sits mid-range. At Toyosu Market in the week ending October 1, 2026, it traded at JPY 1,728 per kg, against JPY 4,463 per kg for fresh domestic bluefin tuna (J-Fish summary of Toyosu data).
Wholesale fish cost is one slice of a menu price. The explainer on why sushi costs so much covers the rest.
SeafoodSource reported in September 2009 that Seafood Watch rated Japanese farmed yellowtail “avoid”, citing heavy reliance on wild-caught fish for feed and concerns over disease and water pollution. Seafood Watch’s senior science manager added that Japanese yellowtail farms often sit in enclosed bays that flush poorly.
The rating has held. Seafood Watch’s February 2024 recommendation list still marks farmed buri from Japanese marine net pens red, and it gives farmed greater amberjack and yellowtail amberjack from Japan the same red rating. Check Seafood Watch’s live listing for any later change.
Hamachi Sushi FAQ
Which drinks pair well with hamachi sushi?
Sake is the traditional match, and Plating and Pairings also publishes wine pairings for hamachi dishes.
Match the drink to the dressing. Shoyu-dipped nigiri sits fine with sake, while citrus-dressed crudo suits something brighter.
Can hamachi be cooked?
Yes. Japanese kitchens grill the collar as buri-kama, and they use hamachi or buri in buri daikon (simmered with radish), teriyaki and buri shabu (dipped in hot dashi).
Heat kills parasites, so cooked hamachi skips the freezing questions that raw service raises.
Is kanpachi the same as kampachi?
Yes. Both spellings name the same Japanese fish, Seriola dumerili, which is a different species from hamachi.
U.S. labels follow FDA market names, which can attach the kanpachi spelling to another Seriola species. Ask what the fish actually is.
Is frozen hamachi good enough for sushi?
Yes. Japan’s yellowtail exports consist primarily of frozen fillets, according to SeafoodSource, and freezing to FDA parameters is also the step that kills parasites.
Fresh fillets make up the smaller, established export market.
What to Ask Before Ordering Hamachi Sushi
Find out which species is on the plate and whether it was farmed. Then ask how it was frozen or raised, which means a freezing record or a feed statement. The order matters, because each answer depends on the one before it.
Price is a decent sanity check too. Wholesale hamachi at Toyosu ran about 39 percent of fresh domestic bluefin per kilogram in the week ending October 1, 2026 (JPY 1,728 against JPY 4,463), so a hamachi piece priced near the toro on the same menu deserves a question about species and origin.
A counter that cannot answer the question about freezing or feed leaves one route: order the hamachi cooked, and accept losing the raw texture.
Once the order is settled, what goes well alongside sushi rounds out the meal.
