The Secretary said that he wished to raise the possibility of visits to Japan by Nautilus-type nuclear-powered submarines. The submarines are engaged in long cruises and it would be helpful if they could visit Japan occasionally for crew rest and provisioning. The United States recognizes the sensitivity of this issue to Japan but these vessels have nuclear power plants as differentiated from the Polaris-type submarines. He asked whether the visit of nuclear-powered submarines would create much of a problem for Japan.

The Foreign Minister said that while the Japanese people support peaceful uses of atomic energy, they are behind the times both technically [Page 691]and in understanding of the problem. The public still tends to relate anything atomic to nuclear weapons and thereby to the possibility of involvement in a nuclear war. The Japanese Government would therefore like to give further study to this problem before agreeing to the visits of nuclear-powered submarines.

The Secretary said that we would return to this question at some future time. He felt that the key to the problem is gaining greater public familiarity with the normal uses of nuclear energy, as distinct from nuclear weapons, by demonstrating the potential of nuclear power plants in ships. We hope eventually nuclear-powered vessels, including submarines, would be accepted in Japan.

The Foreign Minister said that the Japanese Government could well understand the desirability of inviting nuclear-powered submarines to Japan. However, in all frankness, he felt that considerable groundwork must be laid first among the public. At present, public opinion is not sufficiently aware of the potential uses of atomic energy; and there is also a lack of understanding in the Japan Science Council which has close ties to the left. At present, there is certain to be a great deal of opposition to almost any step relating to atomic energy, including a visit by nuclear-powered submarines. He said that it was a matter of timing and method in Japan so that a situation could be created publicly whereby United States proposals on such subjects would be acceptable. The Secretary said that we would be in touch with the Japanese Government again on the problem.1
