The origin of sushi can be traced back for millennia to the rice fields of Asia - China, to be very precise. Although most people assume that sushi derives its root from Japanese culinary practices, it dates back to a Chinese dish called narezushi. Originally, sushi was introduced in Japan from China around the Nara Period (710-794). The credit goes to the common cultural exchange of rice cultivation art. The original version of sushi was intended to be eaten as a preserved food, made by marinating fish in salt and letting it mature over an extended period of time.

When Tokugawa Ieyasu (a Japanese military leader who helped unify the nation) strengthened its grip over all of Japan in 1603 and moved the capital from Kyoto to Edo (modern-day Tokyo). During the Edo period, Japan was bustling with stores, people, restaurants, and illuminated nightlife. That’s when Nigiri-zushi made its mark. It was fast food that could be eaten immediately after the rice was lightly compressed and combined with raw or cooked seafood on top. It was often served with ginger or wasabi in between. By the end of the Edo period, several other varieties known as the inarizushi and makizushi (rolled sushi) also appeared and the well-known sushi that we know nowadays made its debut. This period was also the godfather of ideas when it came to sushi. People started to use vinegar in the rice, instead of wasting time on the fermentation. This process introduced a new type of sushi: Edomae-zushi.

Some historians also believe that sushi traveled to Japan even sooner. The first reference to sushi appeared in the Yoro Code in 1718, which makes sushi’s birth date in Japan's 8th century. Over the eons, the evolution of sushi has been dramatic. Japanese people started eating three meals a day, boiling their rice for finer flavors and using rice vinegar to ferment the rice more quickly. Undoubtedly the smell of the preserved fish was still strong, but the history of sushi suggests that it helped to fasten up the fermentation process and reduced the time it took to create the actual sushi.

Sushi in the western culture is as much an elite dish as a humble fast food. Although the dish was introduced to the west in the early 1900s after Japanese immigration. The idea of raw fish irked the masses, and the dish wasn’t that popular among anyone except the upper class. After a few years when World War II ended, Japan became the buzzing hub of tourism, trade, and business. By the 1960s, sushi was an incredibly popular dish across American, with many now calling it their favourite dish.
