I guess there are other people who would applaud the japanese to aim for self sufficiency in producing food instead of selling out to corporate interests of few engaging in globalized trade.
If it was sustainable, I would applaud. But the reality is that young people don't want to take over the farms and rural population decreases rapidly. Even with incentives, new people don't want to take over farms because investment needed to modernize them is too important.
I am from Brazil, that is a agriculture powerhouse.
1. Young people here don't want to be farmers either, the ones that do want (me for Example) can't afford the land price anyway.
2. Because exporting the same thing over and over again is way more profitable than selling food to locals, most farms focus on those, we have regions where people eat poorly in the middle of gigantic eucalyptus fields that replaced all farms.
3. Point 2 is so bad we actually import lots of food, most notoriously most of our wheat is imported, some places even sell imported pasta, and most of the imports are mass production crap, for example giant apples with no taste, wheat that only works to make very soft crappy pasta that never befome al dente and has excessive amounts of gluten.
I actually envy Japan and other countries that defend their food security.
