There are several countries in the world that produce rice for sushi. Of course, at the top of the list is Japan but China, Korea and the United States do also produce sushi rice.
There is quite a big difference between the varieties of rice that are produced in the different countries. The rice grain itself may vary in size depending on which country has grown the rice. Of course you have to keep that in mind it will have an effect on cooking the rice.
I have most experience using sushi rice which is either produced in Japan or in the USA.
This is due to the fact that these are the varieties of rice that have available in the stores I shop in Copenhagen. I have equally good experiences with sushi grown in Japan and the United States.
