Here are some specific examples of Japan's role in the Cold War:
* Japan provided logistical and financial support to the United States during the Korean War.
* Japan allowed the United States to use military bases in Japan, including the Yokosuka Naval Base and the Kadena Air Base.
* Japan participated in the United States-led nuclear weapons testing program in the Pacific Ocean.
* Japan joined the United States in condemning the Soviet Union's invasion of Afghanistan in 1979.
* Japan also provided economic aid to South Korea and other countries in the developing world as a way to counter the spread of communism.
In addition to these specific actions, Japan also played a more general role in the Cold War as a symbol of the success of the United States' containment policy. Japan's economic recovery and its emergence as a major economic power showed that the United States' strategy of containing the Soviet Union was working.
