Sashimi doesn’t come with rice. It’s thin slices of raw fish or seafood, served without vinegared rice, so the cut and the freshness of the fish are all the dish has going for it.
Sushi is the one defined by rice (shari). That makes “sashimi sushi” on a menu a pairing of two separate dishes.
Nigiri and maki both carry rice. So does chirashi, which is the one people tend to forget. All of them count as sushi, and sliced fish on its own doesn’t.
Raw fish also has a safety side that most menus never mention. The FDA’s 2011 hazards guidance names sashimi among the products implicated in parasite infection, and one of the freezing schedules it accepts for killing those parasites is -35 C until solid, then 15 hours.
What Is Sashimi, and Is It Sushi?
No. Thinly sliced raw fish or seafood served on its own, without vinegared rice, is a separate dish from sushi and not a version of it.
Rice is what divides them. Sushi has it, sashimi doesn’t.
The rice test
The word sushi itself translates as sour rice (Dictionary.com), and any dish built on vinegared rice qualifies. Raw fish is a common topping, but nothing requires it.
Wikipedia’s sashimi entry notes that plenty of sushi contains cooked seafood, and some has no seafood at all, only vegetables or seaweed. So what actually makes a dish sushi has nothing to do with the protein.
At the table, it comes down to a glance. Vinegared rice under the fish means sushi, whatever the topping. Sliced fish with nothing underneath means sashimi.
Why the two names get mixed up
The two sit on the same menu and both lean on raw fish, and either one arrives with soy sauce, wasabi and pickled ginger. Wikipedia records that many non-Japanese diners use the words interchangeably.
Some reference sources blur the line themselves. Dictionary.com says sashimi is basically sushi without the rice and seaweed. Pogogi goes the other way and says sashimi is never sushi, since the moment vinegared rice is added it stops being sashimi.
I think the Pogogi framing holds up better. It makes rice the test instead of treating sashimi as stripped-down sushi.
The Daily Meal goes a step further. In the strictest sense, sushi refers only to the seasoned rice, and everyday use stretched it into a catch-all term for maki and nigiri. Sashimi falls outside it.
Where Sashimi Ends and Sushi Begins
Vinegared rice under the fish, or wrapped around it, makes the dish sushi. Sliced fish alone stays sashimi.
| Dish | Vinegared rice | How the fish is served | Category |
|---|---|---|---|
| Sashimi | No | Sliced, served alone | Sashimi |
| Nigiri | Yes | Slice set on a hand-pressed oblong of rice | Sushi |
| Maki | Yes | Rolled with rice in seaweed, then cut into pieces | Sushi |
| Chirashi | Yes | Toppings arranged over or mixed into the rice | Sushi |
| Kaisen-don | No, plain steamed rice | Raw seafood over a rice bowl | Rice bowl, not sushi |
Same fish, different dish
A slice of salmon is sashimi by itself and sushi once it’s on rice, a point Pogogi makes outright.
Press that slice onto a hand-pressed oblong of vinegared rice and you get the style known as nigiri sushi, with the topping called neta (The Daily Meal).
Roll it up with rice and nori and the result is maki sushi. Temaki does the same job in a hand-held cone.
None of them are sashimi anymore.
Chirashi and kaisen-don
Chirashi is the confusing one. At sushi restaurants it often means Edo-style chirashi, where slices of sashimi are arranged over sushi rice, according to Just One Cookbook. The rice is vinegared, so the dish counts as sushi.
Kaisen-don puts raw seafood over plain steamed rice instead. Sushi rice is the main difference between the two (Bokksu), and kaisen-don rice is served hot while chirashi rice sits at room temperature (Caroline’s Cooking).
A quick test is whether the rice is seasoned. Hot plain rice makes it a donburi, and cooled seasoned rice makes it sushi.
What Is Sashimi Made Of?
Fresh raw seafood, mostly saltwater fish, sliced and served without rice. Tuna and salmon get ordered the most, with yellowtail and sea bream close behind. Scallop, squid and shrimp fill out the shellfish side, and a handful of non-seafood items show up too.
Fish
- Maguro (tuna) is usually the lean red loin, akami, which is the most common cut (Japan Guide).
- Sake (salmon) is just as popular, and its fattier belly portion is sold as salmon toro.
- Hamachi (yellowtail) is a menu regular alongside saba (mackerel) and aji (horse mackerel).
- Tai (sea bream) is a firm white fish, usually cut thin.
Saltwater fish is the norm. MasterClass notes that freshwater fish is avoided because it carries a higher risk of bacteria and parasites.
Tuna gets graded by fat. Akami is lean, chutoro sits in the middle and otoro is the fattiest. The toro cuts from the belly sell for more than the lean loin.
Published fat figures disagree. Wikipedia’s toro entry has put otoro near 40% fat and bigeye akami near 14%, while Yuzu Omakase gives otoro 25 to 30%, with winter peaks close to 40%.
Fat shifts with catch location and time of year, per Wikipedia, so any single number is a rough guide.
Shellfish, squid and octopus
Scallop (hotate) is served as the thick white adductor muscle, and Japan Guide names Hokkaido and Aomori among the best producers.
Of the shrimps eaten in Japan, amaebi (sweet shrimp) is the one most commonly served raw. Squid (ika) ranks among the most common sashimi, with a firm, mild mantle. Uni (sea urchin) sits at the expensive end.
Octopus breaks the raw rule. Wikipedia notes it is sometimes served cooked because of its chewiness.
Meat and vegetable sashimi
Sashimi names a cut and a way of serving, not only a fish. Dictionary.com says a dish prepared sashimi-style usually just means it is sliced thin.
Basashi is horse meat, torisashi is chicken (often seared on the outside), and beef turns up too. Vegetarian versions use avocado cut to resemble salmon, or konnyaku cut to resemble pufferfish.
Raw chicken is where the rules change. Campylobacter overtook Salmonella and Vibrio parahaemolyticus as Japan’s leading bacterial cause of food poisoning in 2003, and chicken is its main source, according to a PubMed Central review of Ministry of Health, Labour and Welfare statistics.
Food Safety News, summarizing Japanese epidemiology, links torisashi, chicken tataki, raw liver and gizzards most often to illness.
Tataki style
A tataki preparation briefly sears or vinegar-marinates the outside of the fish or meat before slicing (MasterClass).
Katsuo no tataki is the classic version. The bonito is seared outside and raw inside, then served thin with ponzu and garlic or ginger (Gurunavi).
How Sashimi Is Cut
A long single-bevel knife and one pull stroke do the cutting, and the name of each cut describes the slice. Hira-zukuri, a flat rectangular slice, is the standard.
| Cut | Meaning | Shape and typical fish |
|---|---|---|
| Hira-zukuri | Flat slice | Rectangular slice; tuna, salmon and kingfish |
| Sogi-zukuri | Diagonal slice | Angled, thinner, broader face; firm white fish such as snapper |
| Usu-zukuri | Thin slice | Very thin diagonal slice; firm fish such as bream, whiting and flounder |
| Kaku-zukuri | Square slice | Cubes of about 20 mm per side |
| Ito-zukuri | Thread slice | Strips under 2 mm across; garfish and squid |
Dimensions and fish pairings come from Wikipedia’s sashimi and culinary knife cuts entries, with the sogi-zukuri detail from SBS Food.
The yanagiba and the pull cut
The yanagiba is the typical sashimi knife, and Wikipedia’s rundown of what makes it work reads a bit like a spec sheet. The blade is long enough to cut a block of flesh in a single stroke. It’s ground on one side only, which gives a more acute edge than most double-bevel knives.
A concave back (urasuki) helps release the slice from the blade. And you draw the knife toward your body instead of pushing down.
The principle is one pull with the full blade. Sawing back and forth or pressing down defeats the design.
Cutting against the grain
Slice across the muscle fibers, not along them. Chef Ishii, quoted by SBS Food, calls keeping the fish cells as intact as possible the rule of thumb.
In hira-zukuri the knife starts at the right end of the saku (the sashimi block) and works left. Sogi-zukuri starts at the left end with the blade angled to the right.
The angle gives a thinner slice with a broader face, which suits firm white fish.
How to Eat Sashimi Properly
Pick each slice up with chopsticks, dip it lightly in soy sauce, and dab wasabi onto the slice instead of stirring it into the dish. Japan Guide adds a rule of manners about pouring only as much soy sauce as the meal needs.
- Pour a small amount of soy sauce into the dish provided.
- Place a little wasabi, or ground ginger, directly on a slice.
- Lift the slice with chopsticks, not fingers.
- Dip one side lightly, and tilt the dish up if the sauce drips.
- Eat the daikon and shiso between pieces if you like them.
The steps follow Japan Guide’s sashimi page (last updated June 2025) and the Japanese dining etiquette story on Google Arts and Culture.
Wasabi in the soy sauce: where the sources split
Wikipedia’s sashimi entry records wasabi paste being stirred into the soy sauce as a dipping sauce, a habit it says is generally not done with sushi.
Japan Guide calls dabbing wasabi or ginger directly onto the slice the more elegant method, and Google Arts and Culture gives the same instruction.
Tatler Asia makes the practical case in its sushi etiquette guide, saying that mixing blunts the wasabi and muddies the soy sauce.
Dab it.
What the garnishes are for
Shredded daikon sits under the slices and has a fresh, minty taste (Japan Guide). Google Arts and Culture adds that it helps digestion. Shiso leaf is edible too, and squeezing it into the soy sauce adds aroma.
Ginger, either gari (pickled) or grated fresh, is listed among the standard sashimi condiments on Wikipedia.
Where sashimi fits in a meal
Sashimi shows up well beyond sushi counters. Japan Guide lists izakaya and teishoku set meals, along with traditional kaiseki course meals, where it is a standard element.
In a formal meal it often arrives early, according to Wikipedia.
At a sushi counter, omakase, where the chef picks the sequence, sets the order for you. Tatler Asia warns that eating out of order overloads the palate early and dulls the subtler cuts later.
Is Sashimi Safe to Eat?
It can be, with conditions. Sashimi is safe when the fish has been frozen to kill parasites or comes from a controlled source such as pellet-fed aquaculture. Raw fish that skipped both carries a real parasite risk.
Parasite Risk and Freezing
The parasites
The FDA’s hazards guidance names sashimi among the products implicated in human parasite infection.
Roundworms (Anisakis) embed in the intestinal wall and cause nausea, vomiting, diarrhea and severe abdominal pain. Tapeworms (Diphyllobothrium) bring abdominal swelling and cramps, with weight loss and anemia in some cases. Flukes cause abdominal discomfort and diarrhea, and some species migrate to other organs.
The CDC says anisakiasis is most common where raw fish is popular, such as Japan, and that anyone eating raw or undercooked fish or squid is at risk. That is why parasite risk in sushi and other raw fish keeps appearing in food safety guidance.
The freezing schedules
Chapter 5 of the FDA’s Fish and Fishery Products Hazards and Controls Guidance (fourth edition) lays out the freezing regimes that kill parasites in fish intended for raw consumption.
- -20 C (-4 F) or below for 7 days, total time
- -35 C (-31 F) or below until solid, then 15 hours at -35 C or below
- -35 C or below until solid, then 24 hours at -20 C or below
The FDA notes these conditions may not suit fish thicker than 6 inches.
Where the rules disagree and where they fail
Regulators do not share one schedule. At -20 C, the FDA and the Codex fish code both ask for 7 days, while the EU asks for 24 hours.
At -35 C, the FDA and the EU ask for 15 hours, and Codex asks for about 20. The Codex and EU figures come from a Hong Kong Centre for Food Safety summary and a European Commission guide.
Pickling doesn’t replace freezing either. The FDA reports nematode larvae surviving 28 days in a 21% salt brine.
Trimming belly flaps or candling the flesh lowers the parasite count but does not eliminate the hazard, per the same chapter. Farmed freshwater fish can still carry flukes, because those parasites enter through the skin instead of through feed.
What Sashimi-Grade Means
Nothing official. Cook’s Illustrated (America’s Test Kitchen) states that no regulations govern “sushi-grade” or “sashimi-grade”, and the label only reflects the fishmonger’s own judgment that the fish is safe raw.
The FDA’s freezing guidance is a recommendation. Some states enforce it as a requirement, most do not.
Salmon is where the label gets used most, and what sushi-grade salmon actually means depends on the seller’s handling standard. Cook’s Illustrated also rates wild-caught salmon and herring as particularly high-risk.
Ask the fishmonger what the label means and whether the fish was frozen to the FDA schedule.
One FDA exemption is worth knowing, and it’s about roe. Once it’s removed from the sac and rinsed, roe is not likely to contain parasites.
The Origin of Sashimi in Japan
Sashimi got its name in Japan’s Muromachi period (1336 to 1573), but raw fish was eaten long before the word existed. The name means pierced body, from sashi (pierce) and mi (flesh), and Wikipedia notes several theories on its etymology.
Raw fish before the word
Chinese records from the Western Zhou period, around 800 BCE, mention eating fish raw (a Chosun University professor, quoted by Asiae in 2021).
Much later, in the Nara period (710 to 794), namasu reached Japan from China. That’s raw fish and vegetables marinated in rice vinegar (The Nibble). The idea of serving raw fish as an arranged dish followed in the Kamakura period (1185 to 1333), also from China, per Wikipedia.
The Nara and Kamakura dates describe different things, a vinegared dish and a style of presentation, so they do not collide. Together they show how far back the Chinese influence runs.
How namasu became sashimi
In the Muromachi period, aristocrats and samurai began eating seafood uncooked. Shiba Tsuneo’s paper in the Journal of National Fisheries University (2012) says the word sashimi was coined for sliced fish dipped in salt or vinegar.
By the end of the Azuchi-Momoyama period, about 400 years ago, large amounts of fresh sea fish were shipped to Kyoto. In the Edo period, sashimi became a delicacy of ordinary people in Edo (now Tokyo), who dipped it in mustard because wasabi was not yet the standard.
The Chosun University professor quoted by Asiae places the shift to soy sauce and wasabi in the late Muromachi period, when sashimi replaced namasu as the name for raw fish served this way.
Where the sources disagree on dates
Dictionary.com’s entries date the English word sashimi to 1875 to 1880 and sushi to 1895 to 1900. Those are the years the words were first recorded in English, not the years they appeared in Japan, although the site’s sushi-versus-sashimi explainer words them as if they were.
Read as English-language dates, they do not conflict with a Muromachi coinage of the Japanese word. They also say nothing about the age of the dish, since the long history of sushi runs back to fermented narezushi arriving in Japan in the early 8th century (Fine Dining Lovers).
Wikipedia and Shiba’s journal paper both place the coinage in the Muromachi period, so that is the date used here.
Sashimi FAQ
How is sashimi different from ceviche and poke?
Ceviche is fish cured in citrus juice, and poke is marinated raw fish, often served over rice in a bowl. Sashimi is just sliced raw fish served plain.
The FDA lists ceviche alongside sashimi among raw fish dishes implicated in parasite infection.
Is carpaccio the same as sashimi?
No. Carpaccio is Italian, thinly sliced raw meat or fish dressed with oil or sauce, and sashimi is Japanese and comes with soy sauce and wasabi.
SBS Food notes that the broad face of a sogi-zukuri slice also suits carpaccio-style dishes.
Is sashimi healthier than sushi?
Yes, if you count rice and add-ons. Sashimi has no rice, while sushi includes vinegared rice and may carry sauces or fried toppings, according to Japanese Taste.
The raw-fish parasite risk is the same for both.
Who should avoid eating sashimi?
Cook’s Illustrated says no raw seafood should be served to pregnant or immune-compromised people.
Cooked fish, and sushi that contains no raw fish, are the straightforward alternatives.
Can you make sashimi at home?
Yes, using fish sold for raw consumption. Start with hira-zukuri, which chef Ishii calls the easy cutting style for beginners (SBS Food).
What does otsukuri mean?
It’s just another Japanese name for sashimi. Good Luck Trip, a Japan travel site, describes it as raw fresh seafood sliced into bite-sized pieces.
What to Order for a First Sashimi Plate
For a first plate, order from mild to rich. Start with akami or tai, the mild, firm cuts. Salmon or hamachi comes next, buttery and in the middle. Otoro goes last because it’s the richest.
Fat coats the tongue, and otoro eaten first flattens the lean cuts that follow, according to Yuzu Omakase’s guide to bluefin tuna cuts.
The trade-off is that the priciest piece arrives last, so a plate that disappoints on the first two cuts never gets there.
Diners who want to taste the rice side of the menu next can start with the main types of sushi rolls.
Freezing advice for raw fish changes only if the FDA revises chapter 5 of its fourth-edition hazards guidance, which was retrieved in October 2026.
