Breeding is the process of creating new varieties of rice by combining rice varieties in order to make them more resistant to heat, disease, and other factors, and to produce more rice. In order for consumers to buy more rice, we produce rice that is safe and secure, and in order to make it cheaper, we produce rice that can be harvested in large quantities. Rice for business use is rice that has been bred to have good quality and to produce a larger quantity of rice. In Mie Prefecture, "Hoshijirushi" is produced.
