Japan, This and That
Somewhat cynical, but pretty sure I’m not unique with this line of thinking:
The level of destruction in Japan can be compared to after-war conditions.
Which should be a boon to the economy, in a most basic sense. Everything has to be re-built. All raw materials should go up. And whoever makes bulldozers will benefit (Toyota?).
As for 75% of the rice fields being flooded, it shouldn’t have a huge effect on rice prices, at least outside Japan. They only produce about 5% of world’s rice: not much land there.
