Sushi is a traditional Japanese dish centered around vinegared rice combined with various ingredients, most commonly seafood. Elegant in its simplicity yet infinitely varied, sushi has grown from humble beginnings to become a globally beloved cuisine.

At its core, authentic sushi isn’t just raw fish as many assume. In fact, the word sushi refers to the seasoned rice (sushi-meshi) that forms its base. This rice, lightly seasoned with vinegar, sugar and salt, is paired with toppings or fillings ranging from slices of fresh raw fish to vegetables or egg.

The result can take many forms: delicate nigiri, norimaki rolls wrapped in seaweed, temaki cones, chirashi bowls, and more. Sushi’s presentation is often as much an art as it is a meal, with chefs paying great attention to color, texture, and balance.

In Japan, sushi is savored for its purity of flavor. The tender bite of seasoned rice, the melt of fresh tuna, a dab of sharp wasabi, dipped lightly in soy sauce—it’s a harmony of tastes that exemplifies Japanese culinary aesthetics.

Sushi’s long journey from rice fields to fine dining

The story of sushi begins not in Japan, but in ancient Southeast Asia, in the rice paddies along the Mekong River. Centuries ago, before refrigeration, people preserved fish by packing it in cooked rice and allowing it to ferment. This early form, known as narezushi, dates back well over a millennium.

The rice fermented and produced lactic acid, which acted as a preservative for the fish. The fermented fish was eaten, while the rice was often discarded.

This practice spread to China and eventually to Japan around the 8th century. Over time, the Japanese developed a taste for the rice as well, and the fermentation period was shortened. This style, called namarezushi, meant fish and rice were both consumed before fully fermenting.

Fast forward to the Edo period (17th to 19th centuries), and a major evolution occurred. Chefs began seasoning rice with vinegar instead of relying on lengthy fermentation to get that sour flavor instantly. This was the birth of what we now recognize as sushi.

Credit for the invention of hand-formed fast-food sushi, nigirizushi, is often given to Hanaya Yohei, a chef in Edo, around the 1820s. He shaped vinegared rice into small oval balls and pressed slices of fresh fish on top. This “quick sushi” was sold from street stalls and became wildly popular among the bustling city population.

Over the 19th and 20th centuries, sushi moved from street food to indoor sushi counters and restaurants. With the advent of refrigeration after World War II, sushi could be safely enjoyed in more places and began its spread around the world.

The first sushi restaurant in the U.S. is believed to have opened in Los Angeles in the 1960s. From there, sushi’s global journey kicked into high gear, evolving with local tastes as it went.

Sushi types and how they’re made

Sushi takes many delightful forms, but all share one common element: vinegared rice.

Some of the main types include:

  • Nigiri: a hand-pressed oblong of sushi rice topped with a dab of wasabi and a slice of topping such as tuna or ebi shrimp.
  • Makizushi (Rolls): sushi rolled in nori seaweed. Fillings include raw fish and cucumber. Subcategories include futomaki (thick rolls), hosomaki (thin rolls), and uramaki (inside-out rolls like the California roll).
  • Temaki: hand rolls, cone-shaped nori filled with sushi rice and fillings, eaten with the hands.
  • Chirashizushi: scattered sushi served in a bowl with toppings such as sashimi and garnishes.
  • Oshizushi: pressed sushi from Osaka, made by compressing layers of rice and fish in a mold and cut into rectangles.

Sushi rice itself is crucial. Chefs use short-grain Japanese rice known for its stickiness, seasoning it with a precise blend of vinegar, sugar and salt. The balance is key: too much vinegar or sugar can overpower the fish.

Preparation also involves meticulous knife work. Fish for nigiri is cut against the grain in a single swipe to maximize tenderness. Vegetables like cucumber or egg omelet are sliced with equal precision.

Despite popular belief, not all sushi involves raw fish. Cooked or blanched items like shrimp or grilled eel are common. Many vegetarian options exist too, such as cucumber rolls or pickled plum rolls.

Sushi is usually served with three accompaniments: soy sauce for dipping, a dab of wasabi, and gari—sweet pickled ginger to cleanse the palate between bites.

How sushi became a global phenomenon

In Japan, sushi ranges from a quick supermarket lunch pack to high-end omakase experiences where a master chef places each piece on your plate. It’s enjoyed during celebrations and showcases seasonal fish and regional specialties.

Outside Japan, sushi’s global rise is remarkable. It became popular in the United States during the 1980s and 1990s. Adaptations like the California roll, which used avocado and cooked crab, acted as a gateway for many Americans. Today, sushi restaurants are found even in small Midwestern towns.

In Europe, cities like London, Paris and Berlin have thriving sushi scenes. In Asia outside Japan, countries like Taiwan, Singapore and Thailand have localized sushi with local flavors. In Latin America, sushi rolls may include cream cheese or tropical fruits, or even sushi burritos.

Conveyor-belt sushi, or kaiten‑zushi, offers an accessible and interactive dining experience worldwide. Sushi’s social aspect—sharing plates among friends—has helped cement its place in global food culture.

The dish is seen as light and healthy in moderation. Yet sushi’s global popularity has sparked important conversations about sustainability. Overfishing of species like bluefin tuna led chefs and consumers to explore sustainable sourcing or farmed alternatives.

What you didn’t know about sushi

There’s a common misconception: sushi versus sashimi. Sashimi is thin slices of raw fish served without rice. It can be part of a sushi meal, but it isn’t sushi itself.

Originally, sushi rice was considered a means of preservation. Now it’s the star. Master sushi chefs spend months perfecting their rice recipe. Traditionally they shape nigiri to include a specific number of grains—some aim for around 300—so the bite holds together and is just right.

Etiquette matters: sushi is often eaten in one bite, and using fingers is acceptable. Soy sauce is meant to kiss the fish, not soak the rice. Gari isn’t placed on sushi; it’s a palate cleanser between different fish flavors.

Records around sushi are playful: the world’s most expensive sushi was made in 2013 with edible gold leaf, pearls and diamonds. The world’s longest sushi roll measured about 2.5 kilometers and was made in Russia in 2016—testament to sushi’s global reach.

Sushi has also entered pop culture. Movies like Pixar’s “Monsters, Inc.” feature sushi chef scenes. “Sushi art” involves rolling sushi such that sliced pieces reveal intricate images—pandas or flowers Kawaii style.

All these tidbits show sushi’s unique blend of simplicity and sophistication, making it a food that continually fascinates and delights people around the globe.
