The History of Sushi: From Preserved Fish to Modern Delicacy

Culture · 6 min read · Updated October 2026

Early Origins

Sushi's earliest form is generally thought to have developed outside Japan, possibly in Southeast Asia or southern China. Called "narezushi," fish was fermented with salt and rice for months to years. The rice promoted fermentation that preserved the fish, but was discarded before eating. This technique spread to China and eventually Japan.

Introduction to Japan (8th Century)

Narezushi had reached Japan by the 8th century — sushi is listed as a form of tax payment in the Yōrō Code of 718. Over the following centuries the Japanese began eating the fermented rice along with the fish. Funazushi, made with carp from Lake Biwa, is still produced today using methods over 1,000 years old, though it's an acquired taste.

Muromachi Period Evolution (1336-1573)

During this period, fermentation time shortened to about a month, creating "namanare." People began enjoying both fish and rice together while still partially raw. This marked the transition from purely preserved food to something resembling modern sushi.

Edo Period Revolution (1603-1868)

The modern sushi we recognize emerged in Edo (now Tokyo) around 1820. Hanaya Yohei is credited with inventing "edomae-zushi" - placing fresh fish on vinegared rice. This "fast food" was sold from street stalls to busy workers. The name "edomae" means "in front of Edo," referring to fish caught in Tokyo Bay.

Post-War Transformation (1945-1970)

After World War II, sushi stalls were forced indoors for sanitation regulations, creating the restaurant culture. The California roll is usually credited to Los Angeles sushi chefs in the 1960s–70s (Vancouver chef Hidekazu Tojo also claims a version), with avocado standing in for fatty tuna.

Global Expansion (1970-Present)

The 1970s saw sushi explode internationally, particularly in the United States. Kawafuku restaurant in Los Angeles (1966) and increased Japanese business travel spread sushi culture. The spicy tuna roll, usually traced to Los Angeles in the 1980s, catered to American palates.

Modern Innovations

Today's sushi includes fusion creations unimaginable to early practitioners:

Cultural Significance

Sushi represents Japanese values of simplicity, seasonality, and craftsmanship. Sushi chefs (itamae) traditionally train for many years. In 2013, traditional Japanese cuisine, including sushi, was designated UNESCO Intangible Cultural Heritage.

Economics and Industry

Tokyo's Tsukiji (now Toyosu) fish market auctions set worldwide tuna prices. At the first auction of 2019, a single bluefin tuna sold for 333.6 million yen (about $3.1 million). The industry faces sustainability challenges with overfishing concerns.

Future Trends

Sushi continues evolving with sustainability focus, lab-grown fish development, and increased vegetarian options. Technology like AI-powered ordering and automated preparation coexists with traditional craftmanship, ensuring sushi's relevance for future generations.
