August 26, 1941
Notwithstanding representations made by us on successive occasions the United States is treading a course which seems to be bent on exciting public opinion within our country. Beginning the first day of September they are exercising stringent limitations on gasoline shipments essential to our civilian population. At this time they are planning to pass through waters adjacent to our shores with cargoes of petroleum products which should be coming to us. The fact that they are transporting these petroleum products to Vladivostock has dealt a severe blow to the sensibilities of our government and people. At the same time that this brings about grave effects upon Japan and American relations, a terrific blow is being dealt by those in Washington to the whole country far more than you can realize.
This being the case, we are forced to cry out our disapproval of the realization of such measures and the Ministry of Interior as well as the War Ministry are very apprehensive. Therefore, because such measures are not in keeping with the neutrality treaty between Japan and Soviet Russia nor in accord with the interpretation of international law, I would like to have you make representations again to the Secretary of State in order that he may reconsider an immediate cessation of these measures from the general viewpoint of the current Japan-American diplomatic relations. Wire me back as soon as you have filed these representations.
In the event the United States assumes the position that it is impossible to cut off shipments of petroleum products to the Soviet, then as it seems advisable to your Excellency make suggestions that they change the transportation route. However, should they not comply with this request, either, I think it would be wise to try to persuade the American authorities that they revive shipments of petroleum products to Japan immediately.
Furthermore, additional representations have been filed with the Soviet too, as of the 26th.
