From Street Snack to Art: The History of Sushi

Most people think sushi means raw fish. It doesn’t. The real history of sushi starts with fermented rice, a preservation technique developed over a thousand years ago in Southeast Asia, long before Japan entered the picture.

What began as a practical way to keep fish edible for months eventually became one of the most recognized cuisines on the planet.

This article traces that full journey, from ancient narezushi and the fermented fish traditions of the Mekong basin, through the Edo period street stalls where nigiri was born, to the California roll debate and the global sushi market worth nearly $10 billion today.

By the end, you’ll know exactly how vinegared rice replaced fermentation, why Tokyo Bay changed everything, and how a Japanese conveyor belt ended up in airports worldwide.

What Is Sushi

Sushi is vinegared rice combined with other ingredients. That’s it. Most people think sushi means raw fish, but the fish is optional. The rice is not.

The defining element is shari (seasoned rice), mixed with rice vinegar, sugar, and salt. Everything else, the fish, the nori, the vegetables, are toppings or fillings that vary by style and region.

If you’ve been to a Japanese restaurant, you’ve probably encountered sushi vs sashimi confusion at the table. Sashimi is sliced raw fish served without rice at all. It’s not sushi. A common mix-up, and one that matters if you’re trying to understand what sushi actually is.

The global sushi restaurant market was valued at USD 9.52 billion in 2024, projected to reach USD 17.62 billion by 2032 (Data Bridge Market Research). That growth starts with a dish most people still misidentify.

The Origins of Sushi in Southeast Asia

Sushi didn’t begin in Japan. Its earliest form, narezushi, developed in the Mekong River basin around the 2nd or 3rd century CE, in the region covering present-day Laos, Cambodia, Thailand, and Vietnam.

The people living there had a practical problem: fish rotted fast in a humid climate. The solution was lacto-fermentation, packing fresh fish in salt and cooked rice, letting lactic acid bacteria do the preservation work over months.

Key origin detail: The rice wasn’t eaten. It was the fermentation medium, then discarded. Only the preserved fish mattered.

Food historian Naomichi Ishige traced narezushi’s spread from the Mekong basin to China through Han migration south of the Yangtze River. From China, the technique moved to Japan during the Yayoi period as wet-field rice cultivation took hold.

The character “鮓” (meaning sour or pickled fish with rice) appears in the Chinese text Shiming, written in the 3rd century. That’s the first documented reference to the process that eventually became sushi.

Linguistic evidence from the Khmer language supports the Mekong origin theory. The Khmer word prahoc (fermented fish) is the root of phaak, which means narezushi. The word came with the technique.

Narezushi and Funazushi in Ancient Japan

Japan’s first written record of sushi-like food appears in the Yoro Code of 718 CE, a government document recording taxes paid in fermented fish using the characters “鮨” and “鮓.” It was already considered valuable enough to submit as tribute to the imperial court.

By the 10th century, the Engishiki (an administrative manual) documented narezushi production from multiple regions of Japan, collected as a form of taxation. This wasn’t fringe food. It was a formal part of the economy.

Funazushi: Japan’s Oldest Surviving Sushi

Funazushi from Shiga Prefecture is considered the oldest form of narezushi still made today. It uses nigorobuna, a type of wild crucian carp found only in Lake Biwa, Japan’s largest freshwater lake.

The process is demanding. Fish are salted in early spring, rinsed and dried in summer, then packed in wooden barrels with cooked rice and left to ferment. Minimum aging: one year. Some families age their funazushi for two or three years. The oldest recorded piece was fermenting for 100 years.

The result has been described as tasting like aged cheese. Sour, pungent, complex. Not for everyone, but that’s not the point. Funazushi has been designated a Shiga Prefecture Intangible Folk Cultural Asset since 1998.

The rice was still discarded in early funazushi. Eating it alongside the fish wouldn’t happen until the Muromachi period (1336-1573), a shift that changed sushi’s entire identity.

How Narezushi Was Made

Salt curing: Gutted fish packed tightly in salt, stored under weighted lids for months.

Fermentation: Desalted fish layered with cooked rice in sealed wooden barrels, lactic acid bacteria converting proteins to amino acids over months or years.

Serving: Fish sliced and eaten. Rice discarded (in early versions). The preserved flesh was sour, dense, and rich in umami flavor.

How Sushi Evolved During the Edo Period

The Edo period (1603-1867) is where sushi stops being a preservation technique and starts becoming a cuisine. Two major shifts happened, and both were driven by impatience with fermentation.

First came hayazushi (fast sushi), developed during the early Edo period. Instead of waiting for lactic acid fermentation to acidify the rice, cooks simply mixed rice vinegar directly into cooked rice. The sourness was instant. The fish could be eaten the same day.

This single shortcut eliminated centuries of waiting.

Oshizushi and the Osaka Style

The Kansai region, centered on Osaka, developed oshizushi: fish and rice pressed into rectangular wooden molds called oshibako, then cut into neat slices.

Main characteristics:

• Compact, dense texture from the pressing process
• Mackerel, sea bream, and other cured fish used as toppings
• Vinegared rice replacing fermented rice entirely
• Prepared in advance, not made to order

Osaka was a major trading hub, and oshizushi fit that environment. It could be made in bulk, cut into portions, and sold efficiently. The pressing mold was a practical tool for a city that valued commercial scale.

This Osaka style still exists. Battera (pressed mackerel sushi) remains a regional specialty, and the oshibako mold is still used in traditional Kansai kitchens today.

Why Vinegar Changed Everything

The move to rice vinegar as a fermentation substitute wasn’t just a time-saver. It changed the flavor profile completely.

Fermented narezushi was intensely sour, almost cheese-like, with the fish flavor deeply altered by months of bacterial activity. Vinegared rice was clean, bright, subtly acidic. The fish could now taste like fish.

The red vinegar (aka-su) used in early Edo sushi was made from fermented sake lees by Nakano Matazaemon, founder of Mizkan, a company that still produces vinegar today. It gave the rice a reddish tint and a richer, more complex sourness than modern white rice vinegar.

The Birth of Nigiri Sushi in Tokyo

Around 1824, a chef named Hanaya Yohei set up a stall near the Ryogoku Bridge in Edo (now Tokyo). What he served there became the foundation of every sushi restaurant you’ve ever visited.

Yohei’s method was simple and radical. Fresh fish from Tokyo Bay, placed directly on a small hand-pressed ball of vinegared rice. No fermentation. No pressing. No waiting. Ready in seconds.

Yohei first sold his sushi by carrying a box of it on his back. By 1828, he had a permanent stall. The location was strategic: Ryogoku Bridge was one of the busiest crossing points over the Sumida River, with a constant flow of workers and merchants.

Street Food of the Chonin Class

Nigiri became the food of Edo’s working class, the chonin (townspeople). It was fast, affordable, and eaten standing at street stalls called yatai.

By the time the Great Kanto Earthquake hit Tokyo in 1923, hundreds of these yatai dotted the city. The earthquake collapsed land prices, giving vendors the chance to rent indoor spaces. Within decades, the outdoor stall became the indoor sushi counter.

Edo-period nigiri was different from what we eat today:

• Rice portions were two to three times larger
• Red vinegar (aka-su) gave the shari a dark, reddish color
• More salt, less sugar compared to modern recipes
• Fish was sourced exclusively from Tokyo Bay

Yohei also used specific preparation techniques (called shigoto) to keep fish safe without refrigeration. Lean tuna was marinated in soy sauce (zuke). White fish was wrapped in kombu kelp (kobujime). These weren’t just safety measures; they were flavor enhancements still used in traditional Edomae restaurants today.

Edomae Sushi and Tokyo Bay

Edomae literally means “in front of Edo,” referring to the shallow bay now known as Tokyo Bay.

In the 1800s, this bay was one of Japan’s richest fishing grounds, full of shrimp, sea bream, conger eel, and tuna. Without refrigeration, fish had to move from water to table within hours. Edomae sushi wasn’t just a style choice. It was a geographic necessity.

The 2012 documentary “Jiro Dreams of Sushi” introduced much of the Western world to the philosophy behind this tradition, driving a surge in omakase dining interest globally. By tracking sushi restaurant listings, food historian Samuel Yamashita found Los Angeles alone went from 9 sushi restaurants in 1995 to 115 by 2019.

Sushi Styles That Developed Across Japan

The Edo period didn’t just produce nigiri. Once rice vinegar replaced fermentation and sushi became fast food, regional cooks across Japan started experimenting.

Most of the major sushi styles eaten worldwide today were created during this period. All of them fall under the category of hayazushi (vinegared rice sushi).

Regional Styles at a Glance

Maki Rolls and the Nori Question

Maki sushi developed during the Edo period alongside nigiri. Nori (dried seaweed) production in the Edo Bay region made it a cheap, available wrapping material for working-class food.

Early makizushi was simple: rice and a single filling (pickled vegetable, fish, or egg) wrapped in a full sheet of toasted nori. Hosomaki (thin rolls) and futomaki (thick rolls) were the standard formats.

The inside-out roll (uramaki, rice on the outside) came much later, in North America, as an adaptation for diners who found seaweed off-putting. That’s a different story for a different section.

Kansai vs. Edomae Sushi

The regional split between Osaka and Tokyo shaped two distinct sushi philosophies that persist today.

Kansai approach: Prepared in advance, pressed or molded, ingredients pre-seasoned, focus on visual presentation of the final cut.

Edomae (Tokyo) approach: Made to order, individual portions, chef-to-customer interaction at the counter, fish condition and rice temperature treated as live variables.

Both are legitimate. Neither is the “right” version of sushi. But when people picture a sushi chef working behind a counter, slicing fish and pressing rice for each guest, they’re picturing the Edomae model that Hanaya Yohei built in 1824.

If you’re curious how these types of sushi rolls differ in practice, the regional roots explain most of it.

How Sushi Reached the West

Japanese immigrants brought food traditions to the US West Coast as early as the 1900s. But sushi didn’t gain real traction outside Japanese-American communities until the 1960s.

The turning point was 1966, when Noritoshi Kanai and his business partner Harry Wolff opened Kawafuku Restaurant in Little Tokyo, Los Angeles. Chef Shigeo Saito, brought directly from Japan, ran the sushi counter upstairs while the ground floor served more familiar dishes like tempura and teriyaki.

Kawafuku is widely cited as the first authentic sushi bar in the United States, with a trained Japanese chef preparing nigiri to order.

Kawafuku’s early clientele was almost entirely Japanese businessmen. They introduced sushi to their American colleagues over lunch, and word spread from there. Food historian Samuel Yamashita tracked sushi restaurant listings in Los Angeles from 9 locations in 1995 to 115 by 2019.

Why Los Angeles, Not New York

LA had geographic advantages. Japanese immigrants were concentrated on the West Coast, Mutual Trading Company had reliable supply chains for Japanese seafood ingredients, and Southern California’s food culture was more open to Asian cuisine in the 1960s.

Bluefin tuna had to be imported from Boston for early US sushi bars. Sea urchin required special harvesting arrangements from California waters. The supply infrastructure was already there, which made LA the natural entry point.

Post-war economics also mattered. The wave of Japanese business travelers and executives arriving in the 1970s and 1980s brought per diems and a strong preference for Japanese food, accelerating demand at a critical moment.

Sushi Moves Indoors in Japan

Meanwhile, back in Tokyo, an earlier event had already changed how sushi was served. The Great Kanto Earthquake of 1923 collapsed property values across the city, letting street-stall vendors buy or rent indoor spaces for the first time.

The yatai (outdoor stalls) that had sold nigiri since Hanaya Yohei’s era gradually disappeared. By the 1950s, sushi was served almost exclusively inside restaurants. The sushi counter, not the street stall, became the standard format.

Refrigeration advances in the 1970s then allowed fresh fish to be shipped over long distances reliably, opening Japanese sushi culture to ingredients from outside Tokyo Bay for the first time.

The California Roll and Western Adaptations

The California roll has two origin stories, and neither is settled. Both involve Japanese chefs working in North America, trying to solve the same problem: Western diners who wouldn’t eat raw fish or seaweed.

Ichiro Mashita at Tokyo Kaikan in Los Angeles is one claimant, credited with substituting avocado for toro (fatty tuna) and eventually developing an inside-out version after American customers kept peeling the nori off.

Hidekazu Tojo in Vancouver claims he created the roll independently in the early 1970s, calling it the “Tojo Maki” before it acquired the California name as it spread south. In 2016, the Japanese Ministry of Agriculture, Forestry and Fisheries named Tojo a goodwill ambassador for Japanese cuisine, a nod to his role in the dish’s global spread.

What Changed Structurally

The California roll wasn’t just a new recipe. It changed the physical structure of sushi.

Uramaki (inside-out roll): rice on the outside, nori hidden inside. Created specifically because American diners found visible seaweed off-putting.

Avocado as toro substitute: similar fat content and buttery texture, but available year-round and familiar to Western diners.

Cooked or imitation crab: removed the raw-seafood barrier entirely for first-time sushi eaters.

There are now an estimated 600 variations of the original California roll worldwide (Sushi Guru CLT). That number reflects what happens when a dish escapes its original context and gets adapted by every culture it touches.

How Japanese Chefs Responded

Reactions split along predictable lines. Traditional sushi chefs in Japan dismissed the California roll as not being real sushi. Younger chefs saw it differently.

American-style sushi eventually made its way back to Japan. Restaurants in Tokyo began serving California rolls and Philadelphia rolls, partly as novelty, partly because younger Japanese diners found them interesting. Food researchers from The Asia-Pacific Journal noted that this reverse adoption was viewed as something “cool and hip” rather than a threat to tradition.

The wine that goes with sushi conversation also emerged from this era, as Western diners started pairing bottles with sushi meals rather than sake or beer. Pairing guides covering what wine goes with sushi became genuinely useful as the Western sushi experience grew into a proper dining occasion.

Sushi in the Modern Global Food Industry

Two inventions shaped how most people experience sushi today. One was conceived out of staffing problems. The other grew out of supply chain improvements and economic expansion.

The global sushi restaurant market was valued at USD 9.52 billion in 2024 and is projected to reach USD 17.62 billion by 2032, growing at 8% annually (Data Bridge Market Research). That growth spans every format, from airport grab-and-go to omakase counters charging $400 per person.

Kaiten-Zushi: How Conveyor Belt Sushi Changed Access

Yoshiaki Shiraishi opened the first kaiten-zushi restaurant, Mawaru Genroku Sushi, in Higashiosaka in 1958. The idea came from watching beer bottles travel along a conveyor at an Asahi brewery. He spent five years perfecting the belt speed before opening.

Eight centimeters per second turned out to be the right pace. Fast enough to move plates continuously, slow enough for customers to grab what they wanted without rushing.

Shiraishi’s chain expanded to 250 locations across Japan at its peak (Tasting Table). His patent on the conveyor system expired in the mid-1970s, after which competitors could copy the format freely. Japan had over 4,000 kaiten-zushi restaurants by 2016.

The 1970 Osaka World Expo gave the concept its international debut. Shiraishi opened a kaiten-zushi restaurant at the fair, exposing 64 million attendees from 77 countries to rotation sushi in one event.

The Omakase Counter and the Supermarket Shelf

Modern sushi exists at two extremes, and most people interact with both.

Omakase dining: reservation-only, chef-selected courses, prices from $150 to over $1,000 per person. Masayoshi Takayama’s Masa in New York became the country’s first three-Michelin-star Japanese restaurant, with dinners topping $1,000 per diner.

Supermarket sushi: pre-made rolls in plastic trays, available in grocery stores across North America, Europe, and Australia. North America saw a 44% increase in sushi-focused restaurant chains between 2020 and 2024 (Global Growth Insights).

Both exist because of the same underlying shift: sushi stopped being a niche Japanese export and became a global food category with its own supply chain, training culture, and consumer base.

Bluefin Tuna, Overfishing, and the Sustainability Problem

Sushi’s global spread had consequences. Atlantic bluefin tuna populations declined by an estimated 70% over the past 50 years, driven largely by sushi demand (Global Growth Insights). In the late 1990s and early 2000s, an estimated 50,000 to 61,000 tons of bluefin were caught annually in the East Atlantic and Mediterranean, pushing the species toward collapse (Sustainable Fisheries UW).

International catch quota reductions and management reforms have helped. ISSF’s 2024 report found 74% of monitored tuna stocks are now at healthy abundance levels, up significantly from previous years. Pacific bluefin tuna exceeded international recovery targets a decade ahead of schedule, according to NOAA Fisheries.

Hana Group, one of North America’s largest sushi operators, rolled out robotic sushi preparation systems across 62% of its locations, cutting food waste by 31% and manual prep time by 37%. That’s the direction the industry is moving: automation and sourcing accountability running in parallel.

For anyone planning a wine pairing with Japanese food, the sourcing question now matters as much as the menu itself. Sustainable sushi and premium dining have become linked in a way they weren’t twenty years ago.

FAQ on History of Sushi

Earlier fermented forms existed for centuries before him, but Yohei created what most people recognize as sushi today.

What is the oldest form of sushi?

Narezushi is the oldest form, consisting of salt-cured fish fermented with rice for months or years.

Funazushi from Shiga Prefecture, made with nigorobuna carp from Lake Biwa, is the oldest surviving version still produced today.

When did sushi come to America?

Sushi reached the US in the early 1900s through Japanese immigrant communities, but remained within those communities for decades.

The first authentic sushi bar opened at Kawafuku Restaurant in Little Tokyo, Los Angeles, in 1966.

What is the history of the California roll?

The California roll was developed in North America in the 1960s-70s to appeal to Western diners uncomfortable with raw fish and seaweed.

Both chef Ichiro Mashita in Los Angeles and Hidekazu Tojo in Vancouver claim credit for its invention.

Why did sushi stop using fermented fish?

During the Edo period, cooks began mixing rice vinegar directly into cooked rice, replicating fermentation’s sourness instantly.

This shortcut, called hayazushi, eliminated months of waiting and turned sushi into fast food for the working class.

What is the difference between narezushi and modern sushi?

Narezushi uses lacto-fermentation over months or years. The rice was discarded and only the preserved fish was eaten.

Modern sushi uses vinegared rice as a core ingredient, with fresh fish served immediately rather than preserved through fermentation.

When was conveyor belt sushi invented?

Yoshiaki Shiraishi invented kaiten-zushi (conveyor belt sushi) in 1958, opening his first restaurant, Mawaru Genroku Sushi, in Higashiosaka.

The idea came from watching beer bottles move along a conveyor at an Asahi brewery.

How did sushi become popular worldwide?

Sushi spread globally through Japanese immigration, the California roll’s accessibility, and the 1970s-80s economic boom that sent Japanese businesses abroad.

Advances in refrigeration and supply chains allowed fresh fish to travel internationally, making quality sushi possible outside Japan.

What does sushi mean in Japanese?

“Sushi” refers to vinegared rice, not raw fish. The word derives from an old Japanese adjective meaning sour, a reference to the rice’s acidity.

Raw fish served without rice is sashimi, a separate dish entirely.

Conclusion

This conclusion is for an article presenting how a simple fish preservation method from the Mekong basin became a global culinary force worth billions.

Narezushi, funazushi, oshizushi, nigiri, kaiten-zushi. Each form reflects a specific moment in history, a practical problem solved with available tools.

Hanaya Yohei’s street stall in Ryogoku didn’t just create nigiri-zushi. It redefined what fast food could be, two centuries before the term existed.

The California roll debate, the omakase boom, the bluefin tuna sustainability crisis. None of these exist without that original lacto-fermentation technique developed along the banks of Southeast Asia’s rivers.

Sushi’s evolution isn’t finished. But knowing where it started makes every piece of vinegared rice taste a little different.
