30 OCTOBER 1945. GSB 168 From: War Department To: Commander-in-Chief, Advance Hq. US Army Forces, Pacific, Tokyo

On 19 Nov 1941 Japanese Foreign Office advised its representatives abroad that in case diplomatic relations with United States, Great Britain or Russia were about to be severed a certain signal in form of false weather report would be broadcast in news message and that all code papers were then to be destroyed. Signal was to be "Higashi No Kaze Ame" (east wind rain) in case of break between Japan and United States, "Kitano Kaze Kumori" (north wind cloudy) in case of break between Japan and Russia and "Nishi No Kaze Hare" (west wind clear) in case of break between Japan and Great Britain. Congressional committee investigating Pearl Harbor attack has requested that Japanese records and authorities be examined to ascertain whether any signal implementing this or any similar code was in fact transmitted on or prior to 7 Dec and if so exact time and manner of transmittal. Inconclusive evidence available here suggests such signal may have been transmitted on or about 4 Dec. Request that all reasonable steps be taken to obtains such information and that this request and resulting information receive no publicity.

BSG 196                                             13 NOVEMBER 1945.
From: Commander-in-Chief, Advance Hq. US Army Forces Pacific, Tokyo.
To: War Department.

Reference message 1 November requiring search of Jap records and interrogation of authorities to ascertain whether an implementing signal to circulars 2353 and 2354 (see GSB 180) Tokyo Foreign Office 19 November 1941 was ever transmitted. Investigation discloses that all pertinent records were burned prior to emperor's rescript of 14 August 1945. Interrogation of authorities so far has resulted in absolute denial of transmission of such an implementing message and existence of any prearranged instructions which would permit transmission of such an implementing signal. It would help the investigation if pertinent authorities could be confronted with circulars 2353 and 2354. This has not been done before in order to avoid disclosing to the Japanese the fact that we had this info. Investigation will be continued but without much prospect of success unless appropriate authorities can be confronted with circulars mentioned.


 
GSB 186                                                13 NOVEMBER 1945.
From: War Department.
To: Commander-in-Chief, Advance Hq. US Army Forces Pacific, Tokyo.

Reference BSG 196 you are authorized to confront Japanese officials with copies of circulars 2353 and 2364 but without disclosing when or by what means they were obtained.


 
                                                       21 NOVEMBER 1945.
BSG 210
From: Commander-in-Chief, Advance Hq. US Army Forces Pacific, Tokyo.
To: War Department

In reply to radiogram 31 October 1945, GSB-168, the results of interrogation of number of employees have indicated that signal implementing circular 2353 and 2354, was probably not transmitted prior to 8 December, Tokyo time, but was transmitted by radio voice broadcast at some hour after 0230, 8 December, Tokyo time. Exact hour unknown. No evidence can be obtained that implementing signal was transmitted by radio telegraph. 1 employee, now in Tokyo, states that he received radio voice broadcast signal in Rangoon at 0930, 8 December, Tokyo time (0630 Rangoon time). No info has been obtained that any signal implementing similar code was transmitted.

As stated in my message number BSG-196, the burning of pertinent records prior to Emperor's rescript of 14 August 1945 precluded obtaining info on this subject from that source.

Furthermore, individuals who were in authority at time under consideration admitted nothing until they were confronted with circulars 2353 and 2354 of Tokyo Foreign Office, 19 November 1941, pursuant to authority contained in your GSB-186.

These employees did not learn when or by what means these circulars were obtained.

Further investigation here appears unprofitable. Request authority to discontinue it.

GSB 196
From: War Department
To: Commander-in-Chief, Advance Hq. US Army Forces Pacific, Tokyo

Reference BSG 210. Only use of Winds code (either voice or radio telegraph) shown here by available contemporaneous records is voice broadcast from Tokyo between 01302 and 0935 on 8 December Tokyo time using code words referring to British Japanese relations. In order to assist in evaluating information given in your BSG 210, Joint Congressional Pearl Harbor Committee desires to know first whether persons who conducted interrogation or those who were interrogated had any knowledge that prior to the interrogation of the United States had information establishing use of Winds code on 8 December Tokyo time, and, secondly, if such persons did have such knowledge, whether they knew that the United States had no definite information establishing use of Winds code at any time prior to 8 December Tokyo time. Prompt reply will be appreciated.


 
                                                      27 NOVEMBER 1945.
BSG 214
From: Commander-in-Chief Advance Hq. US Army Forces Pacific, Tokyo
To: War Department

Reur GSB-196 persons who conducted interrogation had no knowledge that prior to interrogation United States had info establishing use of Winds code on 8 Dec Tokyo time. Persons who were interrogated were not asked whether they knew that United States had info establishing use of Winds code on 8 Dec Tokyo time. Also, interrogated persons were not asked whether they knew that United States had no info establishing use of the Winds code at any time prior to 8 Dec Tokyo time. They will be questioned on these points at once and answers provided. Employee referred to in my BSG-210 who stated that he received voice broadcast signaling Rangoon at 0930, 8 Dec Tokyo time (0630 Rangoon timed may have meant that he received code words referring to British-Jap relations. He will be questioned again. This partial reply is made now and full reply will be forwarded as promptly as employees can again be found for questioning.


 
                                                          NOVEMBER 1945.
GSB 197
From: War Department
To: Commander-in-Chief. Advance Hq. US Army Forces, Pacific, Tokyo.

Information supplied in BSG 214 is believed sufficient answer to Committee's question, which was directed towards prior knowledge of interrogators and whether anything had developed in the interrogation which would indicate such prior knowledge on the part of Japanese. It seems clear from your BSG 214 that there was no such indication. Please confirm this.

It is requested that no further interrogation on this point be conducted unless Congressional Committee indicates desire to press inquiry further, in which event you will be advised.

Further interrogation of employee referred to in BSG 210 to ascertain whether broadcast heard in Rangoon used code words referring only to British-Japanese relations would be helpful. Other wise you may consider interrogation completed.


                                                       30 NOVEMBER 1945
BSG 219
From: Commander-in-Chief, Advance Hq. US Army Forces, Pacific, Tokyo
To: War Department

Reur GSB 197 nothing developed during interrogation which indicated on part of Japanese prior knowledge of character stated in your GSB 197.

Employee who heard Rangoon broadcast states he does not recall code words heard but believes they referred to severance of British-Jap relations. This resulted from further questioning of this employee and without prompting as to character of answer given.

                                                 Date: 30 November 1945
Subject: Radio Tokyo Broadcast December 8.
Personnel Interrogated: Mr. Shinroku Tanomogi, Head of Overseas 
   Department of Japan Radio Broadcasting Corporation in December 1941, 
   presently member of the Diet and secretary to the Minister of 
   Transportation.
Interrogator: Captain Peyton Harrison, USNR.
Interpreter: Lt (jg) Stanley E. Sprague, USNR.
Summary:

Mr. Tanomogi, as head of the Overseas Department, was in charge of programs, including news programs, beamed to foreign countries. All news releases were controlled or "censored" by the Information Bureau of the Cabinet, the Communications Bureau of the Communications Ministry, and the General Staff.

Mr. Tanomogi was usually on duty at Radio Tokyo every other night. He was on duty the night of December 7 (Tokyo Time) and stated that the regular schedule of programs was broadcast. At about 0400 on December 8, he received a telephone call from the Information Bureau informing him that Japan was at war and that scheduled programs would have to be rearranged and preparations made for broadcasting important government communiqués. An official of the Information Bureau arrived at Radio Tokyo early on the morning of December 8 to work out details with Tanomogi's staff. Tanomogi remained at Radio Tokyo until about 1800 of December 8. He stated that they broadcast only what was given them by Domei News or by the Information Bureau. "All news was official government news".

Mr. Tanomogi was asked if he remembered the "east wind rain" weather report broadcast about 1500 on December 8. He replied that he was not listening to the broadcasts at that particular hour, but that he had a vague recollection of some such announcement being broadcast among the releases abruptly ordered for transmission that day by the Information Bureau.

Mr. Tanomogi was handed a copy of Drew Pearson's article in the Honolulu Star-Bulletin of November 9, 1945. He stated that he would have known of it if a message such as that described as being broadcast December 4 had been transmitted and that he had no recollection at all of any "east wind rain" report or any similar phrase being broadcast prior to December 8.


 PARAPHRASE OF INCOMING TELEGRAM 

To: London, the Hague and Canberra, November 6, 1945.
From: Secretary Byrnes

The Congressional Joint Committee on the investigation of the Pearl Harbor attack has sent to the Department a communication of which the essential portion is quoted below:

"Under date of November 19, 1941 Japan advised its representatives abroad that if danger arose of a breach of diplomatic relations with the United States, or Russia or the British, and the Cutting off of other means of international communications, an emergency system for warning Japanese diplomatic representatives of impending break in diplomatic relations would be used, by adding in the middle of the daily Japanese language short wave news broadcast the following:

"(1) In case Japan-United States relations were in danger, the words Higashi No Kazeame (East Wind Rain).

"(2) In case of Japan-Russian relations in danger, the words Kitanokaze Kumori (North Wind Cloudy).

"(3) In case Japan-British relations in danger, the words Nishi No Kaze Hare (West Wind Clear).

this signal to be given in the middle and at the end of the broadcast as a weather forecast, 'each sentence to be repeated twice'. This arrangement also said, 'When this is heard, please destroy all code papers, etc.'

EXHIBITS OF JOINT COMMITTEE 3311

"At the same time, on November 19, 1941, the Japanese sent further notice to its representatives that when their diplomatic relations with the United States, Russia or the British were in danger, there would be added at the beginning and at the end of Japanese general intelligence broadcasts words as follows:

"(1) If it were Japan-United States relations, the word 'Higashi'.

"(2) If it were Japan-Russia relations, the word 'Kite'.

"(3) If it were Japan-British relations (including Thai, Malaya, and Nei), the word 'Nishi'.

these words to be repeated five times at the beginning and end of the broadcast.

"The Joint Congressional Committee Investigating the Attack on Pearl Harbor of December 7, 1941 are trying to ascertain whether any broadcast under this system were monitored and overheard, either by the United States or by Australia, the Dutch East Indies or the British, and, if so, on what day and at what time such a broadcast was overheard, and if so the text of the broadcast, and whether either of the three nations mentioned, having overheard the broadcast, advised the United States of the fact. We are particularly interested in the period from November 27th to December 7th inclusive, and suggest that the inquiry first cover that period and then, if time permits, work back to November 19, 1941."

You are requested urgently to inquire of the government to which you are accredited concerning the above and at the earliest possible moment to telegraph a report of the results.

Nothing has been revealed by an exhaustive search of the records of the monitoring service according to the Department of External Affairs. It is stated however that they may have missed certain messages in code as at that time trends only were followed and Japanese broadcasts were not taken down verbatim by the monitoring service.

MINTER.




4(e) DEPARTMENT OF STATE, Washington, December 5, 1945.

MY DEAR MR. MITCHELL: I enclose a paraphrased cable dated December 4, 1945, just received from London in reply to our inquiry of November 6 as to whether the British had monitored and overheard any Japanese broadcasts using the so-called "winds" code between November 19 and December 7, 1941.

PARAPHRASING OF INCOMING TELEGRAM To: Secretary of State, December 4, 1945 From: American Ambassador, London

The Foreign Office has just informed us that while their inquiries are not yet finished, up to the present no evidence has been found that any "wind" message was received before the morning of December 8, 1941, the day following the attack on Pearl Harbor. The Foreign Office says that there was relayed to Singapore from Hongkong a broadcast by the Japanese which contained messages in code and which was received in Singapore six hours following the attack on Pearl Harbor. The text of the Japanese code is not available yet but if desired we will ask the Foreign Office for more particulars.


The following messages appearing on the indicated pages of Committee Exhibit deal with instructions sent in code via ordinary commercial channels of communication, to Japanese representatives to destroy their codes:

Subj: JD-1: 7001, special studies concerning

1. In an effort to locate JD-1 7001 the following sources have been exhaustively studied:

a. numerical file of JD-1 #'s.
b. chronological file of Japanese Diplomatic translations.
c. the "Japanese diplomatic traffic log" for 1941.
d. old GZ card index of Japanese diplomatic traffic, under Tokyo circulars and Washington circuit.

2. A special study of Jd-1 #'s was made to determine the relationship between the date of the message, the date of translation of the message, and the JD-1 #. The results of this study are attached to this memo.

EXHIBITS OF JOINT COMMITTEE 3313

From this study it would appear that JD-1: 7001, if such number was assigned to a translation, was for a message dated 28 November 1941, translated on either 12-2-41 or 12-3-41 by the Army. As all of the JD-1 #'s on both sides of JD-1: 7001 were translated on either 2 December 1941 it seems reasonably certain that the message was dated on or prior to 3 December 1941.

4. Throughout the JD-1 numerical file there are incidents of canceled numbers. The reasons for some of these cancellations are not given: others are given as follows: "duplicate of message previously numbered", "additional part of message already assigned a number", and "number skipped by mistake".

5. In October 1944 and on 14 May 1945 Lieut. Comdr. G. E. Boone called Col. Rowlett at Arlington Hall and secured from him the following information concerning the Army numbering system in 1941: Occasionally numbers were canceled, but there was no indication given of the reason for the cancellation, by whom it was made, nor by whom it was authorized. He stated that there were other cases of numbers canceled in the 1941 file.

The activities of KOO CHOO SUI, backed up by the CHI GOO KAI and the KOO HOO (an intelligence society and a publication), is working hard in our behalf to stamp out anti-Japanism. Several incidents have occurred lately and his opponents are rather belligerent. Consequently, Governmental surveillance over KOO is rather close. From April to September of this year we afforded KOO a subsidy for the KOO HOO and a fund for collecting intelligence, amounting to from 2,000 to 3,000 guilders. KOO is so familiar with the Chinese and natives here that in case of emergency he can do much to help us. That is why I have employed him so far. He is ready at our direction to start the distribution of pamphlets designed to win over as many of his consanguinaries and the natives as possible. I think that we should continue to avail ourselves of his services. He has a family of eight. Therefore, I think we should let him have 3,000 guilders for operating expenses; 15,000 guilders for living expenses, and 12,000 guilders as a subsidy for the KOO HOO as of from October 1st to the end of the year. Will you please, therefore, arrange to appropriate and remit that amount, namely 30,000 guilders.

[1] Secret Top Secret-Ultra From: Tokyo To: Hsinking November 28, 1941. Purple. #782 (corrected to #882).

Re your #751.[a] [no footnote "a" found, LWJ]

1. We have been communicating with the German representatives here, giving them much of the Manchukucan opinion and, as a result of a talk between OTAKI and WCHLTHAT, the final draft for a new German-Manchukuan pact is proposed by Germany as follows:

(a) The title of the pact is "A provisional agreement for extending German-Manchukuoan economic Relations."

(b) This pact is effective until the last day of March next year.

(c) The balance of 85,000 tons of soy beans shall be delivered before the end of March at the old price although the agreement expires the end of January.

(d) 4,500 tons of soy bean oil, including the undelivered balance on the contract for jimson, shall also be delivered by the end of March.

(e) Exchange permits shall be given for the unused balance of German contingent goods specified in the pact of May 31, 1941. (Minister WAGNER must have a list of about one million marks' worth of goods in Japan, Manchukuo, Shanghai and other Far Eastern points.)

(f) Export permits shall be gine [sic] for German goods which are now held or may in the future be held in Manchukuo at the convenience of the holders. If a state of emergency shall arise, this goods shall not be confiscated nor seized. The above should be administered on a rational basis.

[2]

(g) The application of this contract will be acted on by specified conferences of local tradesmen.

(h) The term for repayment of the "W" account shall be extended to May 31, 1942. However, this understanding shall be made directly with the bank at the same time the pact is set up: it will not be mentioned in the pact.

(i) 1,000,000 marks shall be appropriated at the end of November and December respectively and 1,500,000 marks at the end of January and February respectively from the "B" account for repayment of the "X" account. (Although their representatives have already expressed their wishes to WAGNER, when I talked with WAGNER on the 21st I did not mention this. As he believes it should be handled from special funds, I think it is best for Manchukua to negotiate for necessary funds for short term credit under this measure).

(j) Germany will offer credit to a maximum of 10,000,000 marks, because of the reduction in amount of shipments of Manchukuoan products (soy beans and soy bean oil). For this credit a new account, "V", will be set up. Thus, the

EXHIBITS OF JOINT COMMITTEE 3317

"Y" account should be liquidated during the term of the new pact through the 5,000,000 marks from account "B" and soy bean payments, and account "W" should he reduced by at least 1,000,000 marks from soy bean payments.

(k) The balance of account "B" shall be used for payments to Germany. Manchukuo is at liberty to make payments under heading (e) from any account whatsoever.

[3]

(1) The second section and the second paragraph of the third section of the pact of May 31, 1941 (means for conversion of obligations not yet settled at the expiration of the pact) shall be left unchanged.

2. Although Manchukuo will probably want to pay Germany through regular channels, because of the obstacles to transportation I think it would be better to deduct German payments from (a) together with a suitable rate of interest. Moreover, believing that the terms of this pact are reasonable since Manchukuo's credit responsibilities are greatly increased, as soon as they get Manchukuo's approval Germany will send it to Berlin. As they wish to have it returned to Tokyo with the signatures of WCHLTHAT, SPINDLER and the Manchukuoan representatives not later than Christmas, they demand speedy consideration by Manchukuo.

Please press the Manchukuo government for prompt adoption of the above pact and please wire a reply. Since Japan and Germany are virtually in agreement on the Chinese text, please urge them again to let us know at once their opinion of the German-Manchukuoan understanding mentioned in our secret message #474 [a] dated September 27th (German edition: German text).

This telegram has been discussed with military authorities and Vice Minister MIURA.

#766. (Primary importance)

According to reports received from the Vatican through CICOGNANI, the Papal representative in Washington, many indications are evident that Japan forms a great obstacle to the United States' early termination of the present anti-Axis war. Public opinion in the United States is that America would be able to achieve victory for Great Britain simply by large-scale production of military supplies if it were not for this obstacle. In the event of a Japanese-American clash, assistance to England and the Soviet would decrease, making necessary American military intervention by means of forces on the European continent. Moreover, there are a great many who believe that during American-Japanese negotiations Japan put forth stipulations encroaching upon American interests and honor and so causing conditions to become extremely delicate.

3318 CONGRESSIONAL INVESTIGATION PEARL HARBOR ATTACK

There were also reports to the effect that the difficulties of Japanese-American negotiations constrained the Interventionist faction headed by the President and strengthened the position of the Isolationists.

Local military intelligences are as follows. For you information.

1. At the military review in celebration of the anniversary of the revolution 47 airplanes of an unrecognizable type flew over the city of Kuibyshev. They were definitely of American design and construction. It seems that large numbers have recently been arriving.

(The above is a report of the Japanese Military Attaché in the Soviet.)

2. Large bodies of anti-Communist mobile forces are fighting in the vicinity of Mininsk (Russe) and Barugujin [a] (south of Krusnoyarsk), destroying lines of communication and attacking the Kolhoz and Sofhoz. (The above is a spy report.)

3. The 39th Sharpshooters Division (in the neighborhood of Kogaiko [a]) has executed before the firing squad 20 unsuccessful deserters who tried to get into Manchukuo between May and November. To date, 46 Soviet troops have deserted. The Soviet, in order to prevent desertion, has moved certain detachments away from the border or have strung charged barbed wire fences along the border. Another means which they are utilizing is making the regiment responsible for detachments from which there have been deserters. (The above is intelligence of primary importance.)

[2]

4. Recently to the Ude Front, the surveillance troops of the outer Mongolian area have within the last few days deliberately trespassed on Mongolian territory several times, even to the extent of 10 to 20 kilos. They are taking a strong, hostile attitude toward Japanese surveillance troops. (The above is intelligence of primary importance.

Remarks by Carter; They are getting a more complete picture of the operations now and it is evident that at 2130G the Tokyo weather is transmitted and at 2200G the Tokyo weather and weather for other prefectures. Reception is getting better and estimate efficiency on this assignment has increased approximately twenty-five percent.

Foned [sic] Col. Bratton and gave him the message at 7:50 p. m.

Remarks by Col. Bratton: Results still negative but am pleased to receive the negative results as it means that we have that much more time. The information desired will occur in the middle of a program and possibly will be repeated at frequent intervals (Asked Col. Bratton if I should communicate the information to Portland-concerning the fact that the desired data will be in the middle of a program.) No. I will have a conference with Lt.

                                           Washington, February 4, 1946.

The Honorable SETH W. RICHARDSON, General Counsel
    Joint Committee on the Investigation of the Pearl Harbor Attack
       Congress of the United States.

DEAR MR. RICHARDSON: Enclosed are paraphrases of three telegrams received regarding the "winds" message, supplementing previous correspondence on this subject.

Sincerely yours,

                                               HERBERT S. MARKS,
                                      Assistant to the Under Secretary.
Enclosures:
   1. Telegram from London, December 15, 1945;
   2. Telegram from The Hague, January 26, 1946:
   3. Telegram from London, January 31, 1946.

TELEGRAM RECEIVED FROM THE AMERICAN EMBASSY AT LONDON, DATED DECEMBER 15, 1945 (PARAPHRASE)

This morning we had a conversation regarding the "winds" messages with a Foreign Office Japanese expert who was in the Foreign Office immediately preceding and at the time of the attack on Pearl Harbor. He declares that, so far as he knows prior to December 8, 1941 no such messages were received. Investigation is still being carried on but the Foreign Office has as yet no information which would change the statement contained in the Embassy's telegram of December 4, 1945 on this subject.

TELEGRAM RECEIVED FROM THE AMERICAN EMBASSY AT THE HAGUE, DATED JANUARY 26, 1946 (PARAPHRASE)

We have been informed by the Foreign Office in a note dated January 24 that all reports of monitored Japanese broadcasts were destroyed before the invasion of the Netherlands East Indies by the Japanese. The same is true of the archives of the Netherlands Indies Government. For this reason the Foreign Office regrets that it is unable to supply the information which has been requested by the Congressional Committee investigating the Pearl Harbor attack.

TELEGRAM RECEIVED FROM THE AMERICAN EMBASSY AT LONDON, DATED JANUARY 31, 1946 (PARAPHRASE)

The Foreign Office states that the investigation requested in the Department's telegram 9745 of November 6, 1945 has drawn a complete blank and that it does not seem worthwhile to make any further investigation.
