Sashimi (刺身) is raw seafood — typically fish — sliced and served with soy sauce and wasabi, sometimes with additional condiments like ponzu, grated daikon, ginger, or green onion depending on the fish. The quality of sashimi is determined entirely by the quality of the fish: its freshness, its sourcing, and how it was handled from catch to plate. The chef's primary contribution is selection and cutting.
This guide covers the major sashimi types, what distinguishes them, how seasonality affects quality, and how to navigate a sashimi menu.
Maguro (鮪) — Tuna: The Three Cuts
Tuna is the most prestigious sashimi fish in Japan. The most prized species is hon maguro (本マグロ) — Pacific bluefin tuna (Thunnus orientalis). Within a bluefin tuna, different sections of the fish have completely different flavor and fat content:
Akami (赤身, "red meat"): The lean loin section of the tuna — the portion that sits furthest from the fatty belly. Deep red, firm, clean iron-forward flavor, minimal fat. The least expensive tuna cut; the most common tuna in mid-range sushi. Also the cut used for tuna tataki (seared exterior, raw interior) and tekka maki (tuna roll).
Chutoro (中トロ, "medium fatty"): The intermediate section between the lean loin and the fatty belly — marbled with fat but not overwhelmingly so. Richer than akami, melts more in the mouth. Considered by many professionals the best balance in tuna: enough fat for richness without the overwhelming unctuous quality of otoro.
Otoro (大トロ, "large fatty"): The fatty belly section of bluefin tuna — the most marbled, most expensive, most intensely rich cut. The fat content in otoro is so high (can exceed 30% of weight) that it literally melts on the tongue. Correctly cut otoro should require almost no chewing; the fat provides a singular sensation. Very expensive; not available at all restaurants.
Other tuna species:
- Kihada maguro (黄肌鮪, yellowfin tuna): lighter colored, leaner, more available; less prestigious than bluefin but genuinely good
- Minami maguro (南マグロ, southern bluefin tuna): Southern Ocean bluefin; excellent quality, similar to Pacific bluefin
- Binnaga (ビンナガ, albacore): the lightest tuna; white-fleshed; less rich; used for canned tuna globally
Seasonal note: Bluefin tuna quality peaks in winter (December–March) when the fish have accumulated maximum fat for the cold season.
Sake (鮭) — Salmon
Norwegian farmed Atlantic salmon is now one of the most consumed sashimi items worldwide — but it is a relatively recent addition to the Japanese sashimi canon. Wild Japanese salmon was historically considered too parasitic (from Anisakis roundworm) for safe raw consumption. The development of parasite-tested farmed Norwegian salmon in the 1980s–90s changed this.
What salmon sashimi provides: The bright orange color, high fat content, and mild sweet flavor make salmon immediately accessible — it is the sashimi most people encounter first.
Quality markers: Deep orange color (not pale pink); firm texture that springs back when pressed lightly; no strong fish smell (fresh salmon has almost no smell beyond faint marine note).
Seasonal salmon variations: Some Japanese restaurants serve wild salmon products in season:
- Ikura (イクラ) — salmon roe, not sashimi proper but related
- Sujiko (筋子) — cured salmon roe in the membrane
Hamachi (ハマチ) / Buri (ブリ) — Japanese Yellowtail / Amberjack
Hamachi and buri refer to the same fish (Seriola quinqueradiata) at different stages of maturity — hamachi is the farmed juvenile; buri is the mature wild adult. Both are popular sashimi; their characters differ:
Hamachi: Younger, farmed; lighter fat content; milder flavor; the yellowtail in most mid-range Japanese restaurants worldwide.
Buri (winter wild): Wild adult yellowtail; significantly higher fat content in winter (kan-buri, 寒ブリ — "cold season yellowtail"); the flavor becomes richer and more complex. Considered one of the great seasonal sashimi products.
Buri is a classic example of shun (旬 — seasonal peak): buri caught in December off the Sea of Japan coast (particularly Toyama Prefecture, famous for Himi buri, 氷見ぶり) during their southern migration is among the most prized sashimi ingredients in Japanese cuisine.
Tai (鯛) — Sea Bream (Red Snapper)
Tai — typically madai (真鯛, red sea bream) — is the most culturally significant fish in Japanese cuisine: the word tai is embedded in medetai (めでたい, "auspicious"), making sea bream the fish of celebrations, new years, and weddings.
As sashimi: Firm, white flesh; delicate, clean flavor; lower fat content than tuna or yellowtail; a study in restraint. The flavor is subtle enough to appreciate the quality of the soy sauce and the freshness of the fish.
Sakura dai (桜鯛, "cherry blossom sea bream"): Spring sea bream (madai in spawning condition, March–May) is considered peak quality and is called "cherry blossom" for its seasonal timing.
Ika (イカ) — Squid
Squid sashimi (ika sashimi) is served either as thin cut strips or as the entire mantle piece with cross-cut scoring that creates a textured, slightly crispy pattern when the squid releases its juices. The texture: firm-chewy, almost crunchy, with a subtle sweetness. Very fresh ika has a translucent quality.
The cephalopod distinction: Unlike fish sashimi, which has a soft-to-firm range, squid provides a fundamentally different textural experience — the muscle structure of cephalopods is fibrous and firm in a way that creates a satisfying chew without the tenderness of fish.
Sumi ika (スミイカ, cuttlefish): Japanese cuttlefish sashimi is even creamier and more delicate than squid; available primarily in Tokyo Bay area.
Tako (タコ) — Octopus
Octopus is almost always served cooked in sashimi contexts — raw octopus has an unpleasantly tough, rubbery texture; cooking (typically poaching or boiling) converts the collagen and makes it tender. The cooked octopus is sliced into thin pieces showing the suckers on one side.
Flavor: Mild, slightly sweet; the suckers provide a different texture from the arm meat. The purple-brown skin color is retained in proper preparation.
Note: Unlike fish, squid, and scallops, tako is not technically raw — it is cooked sashimi in the way that tako is treated in Japan.
Hotate (帆立) — Scallop
Raw scallop sashimi — the large, white, sweet muscle of the scallop, sliced into rounds or served whole. One of the sweetest and most immediately appealing sashimi items for people new to raw seafood; the sugar content of scallops gives them a clean sweetness absent from most fish.
Hokkaido hotate: The most prized scallops in Japan come from Hokkaido — particularly the large ezo hotate (エゾ帆立) from cold northern waters. The flavor and texture differ detectably from warmer-water scallops; cold water scallops are firmer and sweeter.
Uni (ウニ) — Sea Urchin
Sea urchin gonads (not roe — the reproductive organs of both male and female sea urchins) are the edible part, served on small wooden trays or as sushi. They are the most polarizing sashimi item:
The flavor: When fresh and high-quality: intensely briny, oceanic, sweet, creamy. A flavor with no equivalent in the food world. When not fresh: Bitter, ammonia-like, strongly fishy. Uni is the most time-sensitive sashimi ingredient — quality degrades within hours after harvest.
Grades and species:
- Murasaki uni (紫雲丹): purple sea urchin from Japan's coasts; yellow-orange; sweet
- Bafun uni (バフンウニ): horse dung urchin (the name refers to the shape); darker orange; more intensely flavored; generally more expensive
- Hokkaido uni: considered the best quality in Japan — cold, clean water + specific algae diet
How to Eat Sashimi Correctly
With wasabi: Place a small amount of wasabi directly on the fish, then pick up with chopsticks and eat in one piece. Do not dissolve wasabi into the soy sauce — the wasabi is between the fish and the palate, not diluted into the dipping liquid. (See also: real wasabi guide.)
Dipping: Dip briefly in soy sauce — the fish side, not the cut side, which absorbs more soy and over-salts.
The accompaniments:
- Shiso (大葉): perilla leaf; eaten with the sashimi, not as garnish — the herbal brightness provides contrast
- Daikon oroshi (大根おろし): grated daikon; cleanses the palate and adds moisture
- Momiji oroshi (紅葉おろし): daikon grated with chili pepper; often served with richer fish
Ordering sequence: In a full sashimi meal, progress from lightest to richest — start with white fish (tai, hirame), move through tuna, and finish with the most intensely flavored items (uni, fatty toro). This preserves palate sensitivity for the delicate flavors.
Seasonal Guide (Japan)
| Fish | Peak Season | |------|-------------| | Otoro (bluefin tuna) | Dec–Mar | | Hamachi/buri yellowtail | Nov–Feb | | Tai sea bream | Mar–May (sakura dai) | | Ika squid | May–Aug | | Uni sea urchin | Jun–Aug (varies by region) | | Sake salmon | Year-round (farmed) / Autumn (wild) | | Hotate scallop | Feb–May |
Shun — eating at seasonal peak — is a core principle of Japanese seafood consumption. A fish caught in its peak season, from its best regional source, handled correctly, is a categorically different product from the same fish out of season. This is why experienced Japanese diners ask what's good today rather than ordering from a fixed list.
