There are many countries that produce rice for sushi such as Japan, the United States, Korea, Italy, and Thailand.
Using Japanese-produced sushi rice is not a must. In Japan, there are many different types of sushi rice of different grades. Japanese sushi rice is not always the best choice if you are not used to cooking sushi rice.
Some Japanese rice varieties are harder to cook than others, so buying Japanese sushi rice is not always an advantage.
On the Sushi course for beginners I talk more about which rice is best for Sushi.
