The yen crisis is the fault of the Japanese government, for accepting to do what America wants them to do: to become another military power and to allow the US to have military bases in Japan.

This destroyed the thriving Japanese economy. Thriving because they dedicated their intelligence, research, efforts to develop what enhances human life: electronics, (radios, TV, transistors, recording equipment, motorcycles, fabrics, pianos, toys, etc., etc.

Using their brains to destroy humanity, buildings, nature, etc, also destroyed their economy.

In Militarism and its industry, the ONLY beneficiaries are the politicians involved. The rest is all loss.
