1. Sushi started as a street-side cheap food

There was a time when sushi was not considered a delicacy to be enjoyed at fine dining restaurants.

Customers did not need a credit card to enjoy a lavish sushi spread.

It started as a cheap food sold at street-side stalls to provide quick lunch to people who did not have time to sit down and eat.

2. A 1923 earthquake changed the fate of sushi

The tragedy and devastation brought about by the 1923 earthquake had far-reaching effects and caused the land prices to decline significantly.

It offered an opportunity for the sushi vendors to take their stalls indoors and this led to brick-and-mortar sushi-ya.

By the 1950s, sushi was mostly served indoors at restaurants.

In the 1970s, the modern advances in refrigeration technology and the ability to send sushi-grade fish to long distances increased the demand for premium sushi in Japan.

5. Hanaya Yohei – the inventor of sushi in Japan

Hanaya Yohei is credited as the inventor or introducer of sushi in Japan close to the mid-1800s, during the end of the Edo period.

8. The green paste is not real wasabi 

A traditional plate of sushi will have a green paste known as ‘wasabi’ at the side. However, most places don’t serve the real thing that comes from the rhizome of wasabia japonica plant.

Instead, it is substituted with horseradish, cornstarch, mustard flour, and green coloring. 

Most people have never tasted real wasabi, but the substitute which tastes almost similar. Authentic wasabi is very expensive and often served in high-end sushi restaurants for an extra price.

Most of the mid-range restaurants serve fake stuff and customers don’t mind it.

9. Wasabi was used to kill parasites

The heat of real wasabi comes from the antimicrobial chemicals present in the plant, and it was used in sushi to kill any parasites and microbes in raw fish.

With advances in technology, fish and seafood are now flash-frozen, ruling out the fear of parasites. However, wasabi paste is still served with sushi as a tradition.
