The popularity of sushi in Japan may have been associated with Buddhism.
Buddhism was imported in the 6th century AD, and quickly became one of the major religions. One of the rules of Buddhism was to restrain from eating meat, and fish was not counted as such.
Also in 1901, Luigi Bezzera patented his first coffee maker and became an innovator in the field.
However, he could not sell it, only done by Desiderio Pavoni, who refined Bezzera’s invention and marketed it.He presented it at a trade fair in Milan in 1906.
