Question: Who invented sushi
About the article "Sushi", section "History".

Candidate passages:
Conveyor belt sushi was invented by Yoshiaki Shiraishi (1914–2001), who had problems staffing his small sushi restaurant and had difficulties managing the restaurant by himself.
He got the idea of a conveyor belt sushi after watching beer bottles on a conveyor belt in an Asahi brewery.
After five years of development, including the design of the conveyor belt and the speed of operations, Shiraishi opened the first conveyor belt sushi "Mawaru Genroku Sushi" in Osaka in 1958, eventually expanding to up to 250 restaurants all over Japan.
However, by 2001, his company had just 11 restaurants.
Shiraishi also invented a "robotic sushi", served by robots, but this idea has not had commercial success.
Initially in a conveyor belt sushi restaurant, all customers were seated to face the conveyor belt, but this was not popular with groups.
Subsequently, tables were added at right angles to the conveyor belt, allowing up to six people to sit at one table.
This also reduced the length of conveyor belt needed to serve a certain number of people.
A conveyor belt sushi boom started in 1970 after a conveyor belt sushi restaurant served sushi at the Osaka World Expo.
Another boom started in 1980, when eating out became more popular, and finally in the late 1990s, when inexpensive restaurants became popular after the burst of the economic bubble.
Recently, Akindo Sushiro became the most famous brand in 2010 in Japan.
A new variant of conveyor belt sushi has a touch screen monitor at every table, showing a virtual aquarium with many fish.
The customer can order the sushi by touching the type of fish, which then is brought to the table by conveyor belt.
An example of this can be seen at the Fugu Restaurant at Eureka Tower, Melbourne.
In recent times, the conveyor belt sushi has inspired the creation of conveyor belt dim sum. 
Sushi of Gari is a Japanese sushi restaurant located at 402 East 78th Street (between First Avenue and York Avenue) on the Upper East Side of Manhattan, in New York City.
It opened in 1997.
The restaurant is known as having an obsessive, cult following.
The chef and owner at nearby Sushi Seki, who uses only the name Seki, spent five years at Sushi of Gari. 
The "Oxford English Dictionary" notes the earliest written mention of sushi in an 1893 book, "Japanese Interiors", where it mentions that "Domestics served us with tea and sushi or rice sandwiches".
However, there is also mention of sushi in a Japanese-English dictionary from 1873, and an 1879 article on Japanese cookery in the journal "Notes and Queries".
A report of sushi being consumed in Britain occurred when the then Prince Akihito (born 1933) visited Queen Elizabeth II during her Coronation in May 1953.
In America in September 1953, Prince Akihito is noted with serving sushi at the Japanese Embassy in Washington, hosted by Ambassador Eikichi Araki (1891–1959).
Sushi was first introduced to the United States in the mid-1960s, possibly at the Kawafuku restaurant in the Little Tokyo neighborhood of Los Angeles.
The California roll was invented in Los Angeles, by substituting a slice of avocado for the seasonal "toro" (fatty tuna) in a traditional maki roll.
