Sushi: A Complete Guide to Every Type and Their History

The cypress counter glows under dim light. Behind it, a man in a white apron lifts a block of tuna, deep red, almost garnet, and glides his blade through it in a single stroke. The slice falls, perfect, onto the board. With a fluid gesture, he presses a warm ball of rice into his left palm, lays the fish on top, shapes the whole thing with a quick squeeze of his fingers, and places the nigiri in front of you on the bare wood. No plate, no garnish, nothing extra. The sushi sits there, between you and the one who made it, in its absolute simplicity. This gesture, repeated millions of times every day across Japan, holds within it centuries of history, technique, and culinary philosophy.

Sushi (寿司, sometimes written 鮨 or 鮓 depending on era and region) is today the most recognized Japanese dish in the world. Yet what most people picture when they hear the word, a slice of raw fish on a bed of vinegared rice, represents only a fraction of a remarkably rich culinary universe. Sushi has not always looked like what we know today. It has crossed centuries, regions, and cultures, reinventing itself endlessly. From fish fermented for months in rice across ancient Japanese provinces to the starred counters of Tōkyō, its story is one of permanent transformation.

A Thousand-Year History: From Narezushi to Edo-Era Fast Food

Narezushi: Preserving Fish Through Fermentation

The ancestor of sushi looks nothing like what restaurants serve today. Narezushi (馴れ寿司, literally "matured sushi") is a fish preservation technique based on lactic fermentation. It originated in Southeast Asia and is thought to have reached Japan between the third and fifth centuries CE, traveling through southern China. The principle is simple: fresh fish is gutted, salted, then wrapped in cooked rice. The whole thing is pressed under weight in a sealed container for months, sometimes over a year. The rice ferments, produces lactic acid, and that acidity preserves the fish while giving it a powerful flavor, both tangy and deeply umami.

The crucial detail is that the rice is not eaten. It serves only as a fermentation medium and is discarded once the fish is ready. Narezushi, strictly speaking, is fermented fish, not "fish on rice." This method still exists today. Funazushi (鮒寿司), a specialty of Shiga Prefecture on the shores of Lake Biwa, is its direct descendant. Made with the funa carp (鮒) from the lake and fermented for one to three years, funazushi is a dish of striking complexity, prized by connoisseurs and ranked among the regional gastronomic treasures of Japan. A single fish can fetch tens of thousands of yen.

From Namanare to Hayazushi: Speeding Up the Process

Starting in the Muromachi era (1336-1573), the Japanese began shortening fermentation times. Namanare (生馴れ) referred to sushi whose fermentation was stopped earlier, while the rice was still partially intact and edible. For the first time, people ate the rice along with the fish. This seemingly minor change marked a fundamental rupture: rice shifted from preservation tool to food in its own right.

The next step, hayazushi (早寿司, "quick sushi"), appeared during the Edo period (1603-1868). Instead of waiting for natural fermentation, cooks added rice vinegar to cooked rice to reproduce, artificially, the acidity that fermentation had taken months to develop. The result: sushi ready in hours instead of months. This innovation radically transformed the dish and paved the way for sushi as we know it.

It was in this context that the first forms of pressed sushi (oshi-zushi, 押し寿司) and boxed sushi (hako-zushi, 箱寿司) emerged, particularly in the Kansai region around Ōsaka. Marinated or cooked fish (not yet raw) was laid over vinegared rice and pressed in a wooden mold, then cut into portions. Battera (バッテラ), the Ōsaka pressed mackerel sushi, is a direct heir of that tradition.

Hanaya Yohei and the Birth of Nigiri-zushi

The real turning point came in the 1820s in Edo, today's Tōkyō. Hanaya Yohei (華屋与兵衛, 1799-1858), an inventive cook, had the idea of serving a slice of fresh fish (lightly seasoned or cured) directly on a hand-shaped ball of vinegared rice. This nigiri-zushi (握り寿司, "hand-pressed sushi") was a revolution: quick to prepare, easy to eat with your fingers, and delicious. It fit perfectly into the culture of yatai (屋台), the street food stalls that fed Edo's enormous urban population, then one of the largest cities in the world.

Yohei's nigiri did not yet use raw fish in the strict sense. The fish was often marinated in soy sauce (zuke, 漬け), cooked, grilled, or cured in vinegar, because refrigeration did not exist. Bluefin tuna, today the king of the sushi counter, was considered second-rate. People preferred sea bream, cooked shrimp, grilled eel, or kohada (gizzard shad). Only in the twentieth century, with the spread of refrigeration and cold-chain transport, did raw fish take the central role it holds today.

引

Sushi was not born of abundance, but of necessity. Preserving fish, feeding a city, eating on the go between errands: every step of its history answered a concrete need, and that original simplicity is what makes it great.

The Great Families of Sushi

The word "sushi" does not refer to a single dish, but to an entire family of preparations united by one common denominator: vinegared rice, known as shari (シャリ) or sumeshi (酢飯). It is the rice, not the fish, that defines sushi. A plate of raw fish without rice is sashimi (刺身), not sushi. This distinction, often ignored abroad, is fundamental.

Nigiri-zushi: The Centerpiece of the Counter

Nigiri-zushi (握り寿司) is the most iconic form: an oval ball of vinegared rice (around twenty grams), hand-shaped by the chef, topped with a slice of fish or seafood called neta (ネタ). Between the rice and the neta, the chef sometimes places a dab of fresh wasabi. Nigiri is ideally eaten in a single bite, in one smooth motion, fish side down so the flavors hit the tongue first.

Every nigiri is an exercise in balance: the temperature of the rice (slightly warm, never cold), the pressure of the shaping (firm enough to hold, loose enough to dissolve in the mouth), the thickness of the neta, the amount of wasabi. A great itamae adjusts these parameters to the fish being served. Fatty tuna (ōtoro, 大トロ) calls for different handling than the sweet amaebi shrimp (甘海老) or squid (ika, 烏賊).

Maki-zushi: The Art of the Roll

Maki-zushi (巻き寿司, "rolled sushi") wraps rice and filling in a sheet of toasted nori seaweed (海苔), using a bamboo mat called a makisu (巻き簾). The maki family comes in several formats:

• Hosomaki (細巻き, "thin roll") contains a single ingredient: cucumber (kappa maki, 河童巻き), tuna (tekka maki, 鉄火巻き), or pickled daikon (shinko maki). Small and delicate, it often serves as an interlude between two nigiri.
• Futomaki (太巻き, "fat roll") is more generous, filled with multiple ingredients (omelette, shiitake mushrooms, kanpyō, shrimp, cucumber). Cut into thick rounds, it is often served at celebrations, notably during Setsubun (節分) in February, when people eat a whole futomaki while facing the year's lucky direction, called ehōmaki (恵方巻).
• Uramaki (裏巻き, "inside-out roll") places the rice on the outside and the nori within. A relatively recent invention popularized in the United States, its most famous representative is the California roll.

Temaki: The Generous Hand Roll

Temaki (手巻き, "hand-rolled") is a cone of nori stuffed with rice and filling, eaten directly with the fingers. Less formal than nigiri, temaki is the sushi of conviviality. At home temaki parties, each guest assembles their own cone from ingredients spread across the table. It is a familiar scene at Japanese family dinners, especially on weekends.

Chirashi-zushi: The Festive Bowl

Chirashi-zushi (散らし寿司, "scattered sushi") is a bowl of vinegared rice topped with an array of ingredients arranged artistically. There are two main traditions. The Edomae chirashi of Tōkyō features slices of raw fish carefully laid over the rice, close to sashimi served on shari. The gomoku chirashi (五目散らし) of Kansai mixes cooked and marinated ingredients (mushrooms, lotus root, omelette strips, shrimp) directly into the rice. Chirashi-zushi is a celebration dish, served for Hinamatsuri (雛祭り, Doll Festival on March 3rd) and major family occasions.

Oshi-zushi and Battera: The Pressed Sushi of Ōsaka

Oshi-zushi (押し寿司, "pressed sushi") is Kansai's great tradition, predating Edo's nigiri. Rice and fish are layered in a rectangular wooden mold (oshibako, 押し箱), pressed firmly, then unmolded and sliced into clean, geometric portions. Battera (バッテラ, from the Portuguese bateira, "boat," referring to the shape of the mold) is the most famous Ōsaka version: vinegar-marinated mackerel, topped with a thin translucent layer of kombu kelp (昆布), pressed onto rice. Its taste is deep, gently tangy, and its visual appearance, with those sharp edges and pearly gleam, carries an elegance very different from nigiri.

Inari-zushi: The Sweetness of Fried Tofu

Inari-zushi (稲荷寿司) is a pouch of fried tofu (aburaage, 油揚げ) simmered in a sweet-salty broth of dashi, soy sauce, and mirin, then stuffed with vinegared rice. Its name refers to the god Inari (稲荷), Shintō deity of rice and fertility, whose messengers are foxes said to love fried tofu. Simple, sweet, and comforting, inari-zushi is a classic of bentō boxes and picnics, beloved by children and adults alike.

Narezushi and Funazushi: Ancestors Still Alive

The funazushi (鮒寿司) of Shiga remains a living witness to the original ancestor. Prepared with the funa carp from Lake Biwa, salted for months, then fermented in rice for one to three years, it offers a striking aromatic complexity: acidic, umami, with cheesy notes reminiscent of aged Roquefort or well-aged Comté. Other regions of Japan preserve their own narezushi variants, like kaburazushi (蕪寿司) from Ishikawa Prefecture, which pairs fish with slices of fermented turnip. These archaic sushis remind us that sushi was born of fermentation, not freshness.

The Neta: A World of Fish and Toppings

Neta (ネタ, slang inversion of tane, 種, "ingredient") refers to the topping that accompanies the rice. Its selection follows a seasonal logic deeply rooted in the Japanese culture of shun (旬), the moment when an ingredient reaches its peak of flavor.

Maguro (鮪, bluefin tuna) is arguably the modern king of the counter. It comes in three cuts: akami (赤身), lean red flesh with a clean flavor; chūtoro (中トロ), moderately fatty, melting and fragrant; and ōtoro (大トロ), the ultra-fatty belly that literally melts on the tongue, veined with white lines of fat. Prices can reach astronomical heights. In January 2019, a 278-kilogram bluefin was sold for 333.6 million yen (around 3 million US dollars) at the first auction of the Toyosu market by restaurateur Kimura Kiyoshi (木村清) of the Sushi Zanmai chain.

Sake (鮭, salmon, not to be confused with the rice wine) is today the most popular neta in Japan according to surveys, even though it was virtually absent from traditional counters forty years ago. Ironically, it was Norway that introduced salmon into Japanese sushi culture. During the 1980s and 1990s, a Norwegian commercial campaign called Project Japan convinced Japanese distributors to adopt farmed Atlantic salmon, fattier and milder than Pacific salmon. The success was immediate.

Other classic neta include hamachi (鰤, yellowtail), hirame (鮃, flounder), aji (鯵, horse mackerel), saba (鯖, mackerel, often cured), ebi (海老, cooked shrimp), amaebi (甘海老, raw sweet shrimp), ika (烏賊, squid), tako (蛸, octopus), uni (雲丹, sea urchin), ikura (いくら, salmon roe, from the Russian ikra), tamago (玉子, sweet-savory omelette), and anago (穴子, grilled and glazed saltwater eel).

Neta preparation techniques are as varied as the ingredients themselves. Kobujime (昆布〆) wraps fish in kombu to transfer the seaweed's umami into the flesh. Zuke (漬け) soaks the fish in soy sauce, a historical preservation technique that gives the fish an amber color and remarkable depth. Aburi (炙り) lightly sears the surface of the fish with a flame, releasing fats and creating a contrast between the caramelized exterior and the raw interior.

The Shari: Rice, the Invisible Heart of Sushi

If the neta catches the eye, it is the shari that makes the sushi. Sushi masters repeat it tirelessly: good sushi is, first and foremost, good rice. Shari represents roughly 60 to 70 percent of a nigiri's volume, and its seasoning, temperature, and texture determine the entire eating experience.

The rice used is a short-grain Japanese rice, often a variety like Koshihikari (コシヒカリ) or Sasanishiki (ササニシキ), known for its sticky yet firm texture and gently sweet flavor. After cooking, the rice is transferred into a large cypress tub called a hangiri (半切り), where it is mixed with a seasoning of rice vinegar, sugar, and salt, while being fanned to cool it quickly and give it a pearly sheen.

Every restaurant has its own vinegar recipe (awasezu, 合わせ酢), jealously guarded, and every itamae adjusts the seasoning by season: slightly more vinegar in summer to counter the heat, a bit milder in winter. Ideal shari sits at human body temperature, around 36 to 38 degrees Celsius: warm enough to release the aromas of the vinegar, but not so hot as to cook the fish.

引

Sushi is often judged by its fish. But a master itamae knows the real test is the rice. Mediocre neta on perfect shari still makes a decent sushi; exceptional neta on bad rice is a failure.

The Itamae: Ten Years to Become a Master

The itamae (板前, literally "in front of the board") is the sushi chef, but the word carries a meaning that goes beyond that of a simple cook. The itamae is a craftsman whose traditional training stretches across a decade or more, within a rigorous apprenticeship system inherited from the Japanese artisan guilds.

The classic path begins with minarai (見習い, "learning by observing"). For the first few years, the apprentice touches neither the fish nor the rice. He cleans, washes dishes, prepares secondary ingredients, and watches the master. Then he learns to cook the rice, season it, roll maki. Only after several years is he allowed to cut fish, and later still to stand behind the counter and shape nigiri for customers.

The itamae's knives are his most precious tools. The yanagiba (柳刃, "willow blade"), long and thin, is used to slice fish in a single fluid stroke, without sawing, to avoid damaging the muscle fibers. The deba (出刃), heavy and thick, is used to fillet and break down whole fish, cut through bones and heads. The usuba (薄刃, "thin blade") is the vegetable knife, capable of extraordinarily fine cuts. All these knives are traditionally beveled on one side only (kataba, 片刃), a feature that allows cleaner cuts but demands superior mastery.

The relationship between the itamae and the customer at the counter (kauntā, カウンター) is an essential part of the high-end sushi experience. At an omakase restaurant (お任せ, "I leave it up to you"), the customer entrusts the entire selection to the chef. The itamae then composes a menu in real time, adapted to the day's catch, the season, and sometimes to preferences he senses in the diner. This silent dialogue between the chef who creates and the guest who savors is one of Japan's most refined gastronomic rituals.

The Art of Eating: Etiquette and Know-How

In Japan, eating sushi comes with a set of conventions that, without being rigid, reflect respect for the work of the itamae and for the ingredients.

Nigiri can be eaten with fingers or chopsticks. Both are accepted, even in the most prestigious restaurants. When dipping nigiri in soy sauce, you flip it to dip the neta, never the rice. Shari would absorb too much soy sauce and fall apart, masking the chef's careful seasoning. Gari (ガリ), the vinegar-pickled ginger, is not placed on the sushi. It is eaten between bites to cleanse the palate and prepare for the next piece. Wasabi (山葵) has already been placed by the itamae between the rice and the fish, and adding more to the soy sauce is considered unnecessary in quality restaurants, though common in more casual places.

The order in which sushi is eaten usually follows a progression: from lighter flavors (white fish, squid) toward richer, more intense ones (fatty tuna, sea urchin), ending with tamago or a maki. This progression is not a whim. It is designed so that each bite can be perceived at its full potential, without strong flavors overwhelming the subtler pieces that follow.

From Kaiten-zushi to the World: Sushi Reinvented

Sushi is not reserved for master counters. In everyday life, Japanese people eat it in much more accessible forms. Kaiten-zushi (回転寿司, "rotating sushi") is a concept invented in 1958 by Shiraishi Yoshiaki (白石義明) in Ōsaka, who had the idea of circulating plates of sushi on a conveyor belt along the counter. Customers grab directly from the belt, and the bill is calculated based on the color and number of stacked plates. Chains like Sushirō (スシロー), Kura Sushi (くら寿司), and Hama Sushi (はま寿司) now serve hundreds of millions of customers per year, with plates starting at 100 yen.

At the opposite end of the spectrum, Tōkyō's omakase restaurants reach the heights of refinement. The most famous of them, Sukiyabashi Jirō (すきやばし次郎), run by Ono Jirō (小野二郎, born 1925), became world-renowned thanks to David Gelb's documentary Jiro Dreams of Sushi (2011). With twenty seats, a fixed menu of about twenty nigiri served in thirty minutes, and a price approaching 40,000 yen per person, Sukiyabashi Jirō embodies the ultimate sushi philosophy: the endless pursuit of perfection through simplicity.

Sushi Outside Japan: Adaptation and Reinvention

Sushi's international expansion truly began in the 1960s and 1970s, with the opening of the first Japanese restaurants in the United States, particularly in Los Angeles. The major turning point was the invention of the California roll in the early 1970s, credited to chef Mashita Ichirō (真下一郎) of the Tokyo Kaikan restaurant in Los Angeles (though the authorship is disputed). By flipping the roll to hide the nori inside (uramaki) and replacing raw fish with avocado and crab (often imitation crab), Mashita created a sushi accessible to Western palates that were wary of visible seaweed and raw fish.

The California roll opened the floodgates. The rainbow roll, the dragon roll, the spicy tuna roll, tempura-fried rolls, sushi drenched in mayo and teriyaki sauce: the West reinvented sushi on its own terms, for better and for worse. In Brazil, the largest sushi-consuming country outside Asia thanks to its huge Japanese diaspora, chefs developed the hot roll (fried sushi) and local combinations with cream cheese and mango. In France, takeaway sushi chains turned maki into everyday grocery fare, available in supermarkets and train stations.

These adaptations sometimes irritate Japanese purists, but they also speak to the universal vitality of the concept. Sushi, with its modular structure (rice plus topping), is an inherently adaptable format. While the boldest creations stray from the original spirit, they have also introduced sushi to the world, pushing millions of people to discover the traditional forms afterward.

In 2013, washoku (和食, traditional Japanese cuisine) was inscribed on UNESCO's Intangible Cultural Heritage list, granting world recognition to a culinary philosophy for which sushi is the most visible ambassador. This inscription does not protect a fixed recipe, but a set of values: respect for seasonal ingredients, harmony of flavors, aesthetics of presentation, and the bond between food and nature. Values that every nigiri, every maki, and every chirashi, from street stall to starred counter, continues to carry across the world.
