The Ambassador in Japan (Castle) to the Acting Secretary of State

[Paraphrase]

53. Yesterday Shidehara assured me that he was exploring every possibility to bring about acceptance by Japan; he stated that he was in communication daily with Hamaguchi and the Navy but that he was not optimistic. He promised to bring the contents of your telegram, which I gave him in writing, to Hamaguchi’s attention immediately. He evidently was opposed to my approaching the Prime Minister directly; if I saw Hamaguchi personally, sensational articles might do great damage for the press is watching every move.

It is Shidehara’s understanding that on replacement of Furutaka class it was agreed that at the next conference Japan should have the right to demand replacement by one 10,000-ton cruiser when our 16th had been built, another when our 17th had been built, and another when our 18th had been built. He stated he was not sure that the United States reserved the right to oppose but that England had reserved this right. I told him that we reserved the right to oppose; that the original idea had been that Japan would claim right to replace Furutaka class by large cruisers in 1943 but I would consult you as to whether the situation had changed any. He was of the opinion that only the British opposed the idea at present. I told him that the United States, I felt, was firm for the 10–6 ratio in 8-inch cruisers because these were associated, in some way, with capital ships, and that because Japan agreed to this ratio the United States had agreed not to fortify its Pacific possessions. Failure to reach agreement, I impressed upon him, could only lead to a full resumption of the building program of the United States.

With regard to the Reed-Matsudaira conversations, Shidehara stated that Japan did not have a full account of them and this was one difficulty because the Navy keeps asking if this or that proposition was advanced by them. I feel that decision cannot be reached until next week for he has not asked for full information on certain points.

Shidehara’s vigor of presentation or willingness to take responsibility should not be distrusted for I am sure he fully realizes that his statesmanship is at stake.
