I feel as if world war two was a good thing to happen the the Japanese government and people. If it were not for the ear, there would have never been sanctions placed on japan, making it so they would have never had the time or resources to invest into other markets. Japan now makes some of the best, most fuel efficient cars in the world. Part of this is because of world war two.
The allied powers took control of the Japanese government and made it s they could not invest in military spending anymore, giving the county a need for a new outlet. Just like the germans and Bavarian Motor works (BMW) Japan started invest in more fuel efficient means of travel. Making it so while the United States was making nuclear bombs, Japan was making cars and technology that the rest of the world would soon need.
The only real problem with this is, the past generation has been so focused on wrong that they had forgotten to have children. Making it so the Japanese are losing their workforce and growing their numbers of retired persons.
Due to this lowering of workers in the market place. The japanese motor companies are showing lower and lower profits as well as a depreciation of the japanese yen. This working class problem is starting to help American companies like ford and GM. Possible undoing any good done by post war repercussions.
