I'd rather have "make peace with your neighbors, promote commercial exchange instead of putting tariffs everywhere making eating fruits a luxury for 90% of your population".
Seriously, agriculture in Japan is retarded. Productivity is extremely low compared to any other developed country, and they use tons of pesticides (way more than anywhere else), because JA forces folks to use them if they want to sell in their right channels. It's just a big mafia at the national level.
If we were to make stuff at home, everything would be much more expensive (you would never get cheap smartphones like you have now) and the level of life would decrease sharply for everyone. Specialized regions for specific products, with proper exchange of goods is what has worked to make everyone richer in the end.
I don't think granting the countryside the power they have has contributed negatively to their economic outlook.
What I am saying is allowing the countryside an outsized say in the politics of the country writ large does not seem to have negatively affected the economy given the structural realities.
Although, granted, the countryside with their bloc keeps successfully thwarting any agricultural reforms (import tariffs). On the other hand, buy local and grow your own critical sustenance (cuz embargoes: see Qatar).
