Premium Tamanishiki (a type of premium sushi rice) is grown in the US and Japan, the US just produces a lot of types of rice. Japonica is a category of rice that includes Calrose for example which is grown primarily in California and is definitely an "American" rice given that it founded the California rice industry
Perhaps because of factual errors (O. s. japonica is not only the same species, but the same subspecies), and pointlessly negative personal opinion making up the rest of your comment.
american white rice is only good when it's transformed into spanish rice, fried rice or creamy rice.
otherwise it's too bland because it's stripped. brown rice is better but still not as good.
both japonica and jasmine rice are good on their own.
love jasmine rice over all of them, it makes your mouth water when you cook it.
edit: who downvotes a comment about rice? lol.
