That clip that I posted in the first post (video only) was censored from the American version of the film. A few months before the movie was released, the US performed an H-bomb test near the Bikini Atoll (Castle Bravo test) which contaminated a Japanese fishing boat with radioactive fallout, resulting in death and serious radiation poisoning.
The H-bomb tests that the US was doing in the pacific were kept secret from the American public, but in Japan the incident (known as the Daigo Fukuryū Maru (第五福龍丸, F/V Lucky Dragon 5 incident) was a major story and fueled discontent about the American occupation of Japan (which was just then coming to a conclusion).
At first, when the fishing boat returned home, nobody knew what that fine dust was that covered the crew. But then it was tested and determined to be H-bomb fallout.
The clip is pretty much a direct reference to the incident, which is probably why it was censored in the US.
Ultimately, the shared love of the movie by American and Japanese audiences contributed to a long and fruitful exchange of trade and culture between the two countries, which continues to today.
