Box 1346 Ann Arbor, Ml 48106-1346 British Library of Political and Economic Science ABSTRACT During the years preceding the outbreak of the Pacific War in December 1941 Britain's Ambassador to Japan was Sir Robert Craigie. His period in Tokyo has since been the object of a good deal of controversy, with some observers criticising him for being an abject appeaser while others have praised him for his skilful diplomacy and for his realism. Similarly his counterpart, the Japanese Ambassador to London, Shigemitsu Mamoru, has had his career much scrutinised, and has been variously labelled as an Anglophile liberal and as a puppet of the Japanese military. Apart from the dispute over their reputations, ,an analysis of the diplomacy of these two Ambassadors during the years 1937-1941 is important because both men were deeply disturbed by the steady deterioration in Anglo-Japanese relations, and sought to alleviate the growing tensions by espousing alternatives, designed to establish the grounds for a new understanding,to the policies pursued by their respective governments. This study analyses both the practicality and the practicability of the policies put forward by Craigie and Shigemitsu, and also shows the influence they exerted on the course of Anglo-Japanese relations. This is done by investigating not only their roles in the major crises that shook relations during this period, such as the Tientsin crisis of 1939, the Burma Road crisis of 1940 and the events immediately prior to the outbreak of war, but also the whole range of issues that led to increased tensions. In particular, emphasis is put on the effect that economic forces had on the relations between the two countries, and how the rivalry arising first from the Depression and second from the outbreak of the war in Europe in 1939 drove London and Tokyo apart; a process which the two Ambassadors were powerless to stop. It is hoped that this will prove to be a useful contribution to the study of the origins of the Pacific War. 2 ACKNOWLEDGEMENTS There are a number of people and institutions that I would like to pay •S tribute to for their assistance in my endeavours.

This document stated in the lofty tones of diplomatic language- 'On the evening of December 7th His Majesty's Government in the United Kingdom learnt that Japanese forces, without previous warning either in the form of a declaration of war or of an ultimatum with a conditional declaration of war, had attempted a landing on the coast of Malaya and bombed Singapore and Hong Kong. In view of these wanton acts of unprovoked aggression committed in flagrant violation of international law and particularly of Article 1 of the Third Hague Convention, relative to the opening of hostilities, to which both Japan and the United Kingdom are parties, I have the honour to inform the Imperial Japanese Government in the name of His Majesty's Government in the United Kingdom that a state of war exists between the two countries.'* This short communication was the culmination of a decade in which, from the time of the Mukden Incident of 18 September 1931, the interests of Britain and Japan in East Asia had come increasingly into a state of collision; but the question arises, was this war unavoidable? To a number of observers on both sides the depth and range of the clash of interests between the two countries, with Britain as defender of the status quo in East Asia and Japan a revisionist power seeking to expel Western influence from the region, meant that a conflict was inevitable. To other interested parties, however, the mutual antagonism between Britain and Japan, the erstwhile allies, was not a cause for fatalism; there were groups in both countries who believed that though the problems that had arisen were serious they were not insoluble, and that in the long term the interests of the two Empires were not incompatible. To these believers in a rapprochement it seemed expedient for Britain and Japan to sit down and negotiate in a spirit of compromise and determination to overcome the obstacle of mutual misunderstanding. There was, however, in the ranks of those who pushed for this policy a further division. On one side there was the group who were at heart sentimentalists and yearned to return to the Elysian days of the Alliance, while on the other there were those who, for reasons of Realpolitik, saw a closer relationship as a vital necessity in the harsh international climate of the 1930s. This difference in motivation meant that there existed different levels of conformity within each of the two groups. The first, because of its belief that closer ties were an end in themselves, showed an identity of view between its members in the two countries. In the second group, because the British and Japanese members saw reconciliation in terms of their own countries' self- interest, they were frequently pursuing different and at times directly contradictory ends: this was a significant disadvantage as the members of this group tended to wield the greater influence in their respective countries. Two figures who can be seen as belonging to this latter group were Sir Robert Craigie, the British Ambassador to Japan from September 1937 to December 1941, and Shigemitsu Mamoru, the Japanese Ambassador to Britain from November 1938 to December 1941. Both diplomats played a vital role in the years leading up to the Pacific War, they were deeply disturbed by the steady deterioration in Anglo-Japanese relations, and sought to alleviate the growing tensions by espousing alternatives to the negative policies pursued by their respective governments; thus they hoped to establish the grounds for a new understanding. In addition, in 1941 they both were aware of how events were pushing the two countries towards war, and urged their respective governments to make compromises to avoid this catastrophe. The fact that these ambassadors shared the view that war could and should be averted, and that their opinions on this matter were rejected by their respective governments, is an important comment on the origins of the Pacific War. It raises a number of questions about such issues as why the views of those who were closest to the heartbeat of Anglo-Japanese relations were ignored, how policy was made, what roles the ambassadors took in this process, and most importantly whether a viable alternative actually existed to the path that eventually led to war. There is, however, a problem here, because the use of Shigemitsu and Craigie as examples of responsible diplomats making realistic assessments of Anglo-Japanese relations is to beg a very large question, as the academic debate over the reputations of both these diplomats has never reached a firm consensus about their position in history. On the subject of Craigie, one extreme view is the criticism levelled by his contemporaries in Whitehall and by some later historians that he was an unrealistic and abject appeaser. A fairly moderate example is the comment made by the Japanese historian Professor Sato Kyozo who wrote in his recent essay 'The Historical Perspective and What is Missing' of Craigie's belief in the importance of the pro-British faction by stating that 'He held the ill-founded and over— optimistic belief that each concession on the British part would encourage this faction and thus help bring about a redirection of Japanese policy.... He tended to conceive of Britain's East Asian policy solely in terms of Anglo-Japanese relations.'2 This view of Craigie is balanced by those who have praised him for both his skilful diplomacy and his vision. An example of this can be seen in the work of Professor Donald Cameron Watt, who praised Craigie in his book How War Came for his 'toughness and negotiating skills' and also noted that he was- '... the ablest member of the British diplomatic service in this period to fail to win proper recognition for his stature and achievements from his fellow countrymen.... He was stigmatized, quite unfairly, as an appeaser...'3 Shigemitsu, for his part, has stirred up an even wider disparity of opinions, in a debate which is complicated further by the fact that he was one of the defendants at the Tokyo War Crimes Trial. To some Shigemitsu was an anglophile liberal struggling against the virulent nationalism in Japan, a view which is most clearly seen in the works of contemporary commentators such as Kase Toshikazu in Japan and Lord Hankey and Major— General F.S.G. Piggott in Britain.4 They saw Shigemitsu as a sincere opponent of the war and as a keen proponent of friendly relations with the West. Kase, who had been Shigemitsu's Private Secretary at the end of the war, described the diplomat in his book Eclipse of the Rising Sun as- '... a man of confirmed liberal views, consistently opposed to any policy of aggression and aggrandizement. Firmly convinced that the triangular cooperation of the major naval powers was the key to world peace, he unswervingly supported the policy of friendly collaboration with England and America.*5 In contrast to this very favourable assessment three articles by the Japanese historian Usui Katsumi have portrayed him as a supporter of expansionism and as a closet ally of the military.6 In particular Usui has studied Shigemitsu's role as the Vice-Minister for Foreign Affairs from 1933 to 1936, and this has led him to write in one essay- 'The Amo declaration, the abrogation of the naval disarmament treaties, the obstruction of the British loan to China and co-operation with the army in its separatist manoeuvres in north China, all these important policies and measures may safely be regarded as part of Shigemitsu’s ovei— all design.’7 Usui also contends that the idea of the need for Japanese expansion in East Asia continued to shape Shigemitsu's mind while Ambassador to Britain. Although the controversy over these two diplomats complicates an assessment of their policies and influence, the actual nature of the disputes qver their reputations has its positive side in that it helps to shed light on other issues which are relevant to the origins of the Pacific War. For example, the denigration of Craigie as an appeaser provides a focus for studying the influence of Britain's appeasement policy in Europe on attitudes towards Japan, while the differing assessments of Shigemitsu are valuable as an entry into the question of what constituted a liberal in 1930s Japan, and whether a powerful moderate pro-Western faction actually existed at all in that country. The troubled reputations are also important because they underline the necessity not to look simply at the ambassadorships of the two men in isolation, which might be the temptation if there was a consensus about their respective positions, but to study how their ideas developed, how and to what extent they exerted influence in the years before their assignment, and finally why they were actually appointed as ambassadors. Before delving into the questions raised by this last passage of the role of the ambassadors before they travelled to their respective posts, it is necessary to say a little about the upbringing, early career and character of the two men. To start with Robert Leslie Craigie, he was born in Southsea in 1883 into the family of a naval officer who went on to become
