Sashimi — Japanese thinly sliced raw seafood and its traditions

Characteristics and serving

At its core sashimi depends on very fresh ingredients and careful handling; many chefs source fish that are eaten within hours of landing. Typical accompaniments include soy sauce, a small amount of wasabi, shredded daikon radish, perilla (shiso) leaves and sometimes grated ginger. Presentation and the thickness and shape of each slice are important: the cut can alter mouthfeel and release different flavors.

Common varieties

Many types of seafood are used for sashimi. Popular choices include:

• Salmon (鮭, sake) — oily and rich.
• Tuna (まぐろ, maguro) and its fatty portion (otoro) — prized for texture and depth.
• Squid (いか, ika) — firm and slightly sweet.
• Shrimp (えび, ebi) — sometimes served raw, sometimes briefly cooked.
• Mackerel (さば, saba) — richer, often marinated.
• Horse mackerel (あじ, aji) — delicate and oily.
• Octopus (たこ, tako) — usually boiled for texture.
• Scallop (ほたて貝, hotate-gai) — sweet and tender.
• Yellowtail (はまち, hamachi) — buttery and mild.
• Pufferfish (ふぐ, fugu) — hazardous unless prepared by licensed chefs.
• Sea urchin (ウニ, uni) — creamy, oceanic taste.
• Whale meat (鯨肉) — historically consumed in some regions.

History and technique

Sashimi evolved over centuries as an expression of seasonality and seafood appreciation. Professional preparation requires skillful use of specialized knives and knowledge of cutting styles: for example, hira-zukuri gives broad, sash-shaped slices while usuzukuri produces very thin, translucent pieces. A yanagiba is a long, single-edged knife commonly used to make clean slices that preserve texture.

Safety, preparation, and etiquette

Food safety is essential because sashimi is often raw. Fish are handled to minimize contamination and, where appropriate, freezing is used to reduce the risk of parasites. Some items are partially cooked or cured for texture or safety; octopus and certain shellfish are commonly blanched. Pufferfish requires specially licensed preparation due to toxic organs.

When eating sashimi, many diners dip a corner of the slice briefly into soy sauce, add a touch of wasabi if desired, and eat it in one bite to appreciate the balance of flavor and texture. Because sashimi highlights a single ingredient, cultural appreciation of seasonality, knife craft and ingredient quality is central to the experience.
