I’m guessing it’s to protect the rice farmers, since if the price decreases enough, they’ll have to either produce other crops or do something else entirely. They’re already having enough problems with people moving to cities, so I doubt they want to create even more incentive.
Farms in Japan are likely disappearing as they are elsewhere. Attempting to protect domestic supply isn’t a bad idea. Doing it in a way that is not detrimental to the population would probably be helpful.
