The European war that began in August 1914 was more than European. Though it was the great European powers that immolated themselves in both victory and defeat, the war was fought around the globe and had immediate consequences for Asia and Japan.
The requirements of the European war were such that Britain, France, Germany, and Russia had to redeploy the troops maintaining their empires in Asia to the European theater of war. At the same time, they all wanted to defend those parts of their empires they could while depriving the enemy of his. Japan was Germany’s foe in this war and a very useful ally of Britain. The war was the final denouement of the tsarist regime in Russia and, when the Bolshevik Revolution had run its course, it would present Japan with a new, virulent, and formidable neighboring regime. Moreover, the successful Marxist revolution in Russia would embolden the nascent communist party in China just as the Bolshevik regime would aid and abet the Chinese revolutionaries who would one day make their own revolution and reshape Japan’s geopolitical reality. In the meanwhile, it was Japan that had an unprecedented opportunity to reshape the geopolitical contours of Asia.
Japan entered the war without hesitation on the side of Britain, sending an ultimatum to Germany on August 15 demanding that Germany withdraw all naval forces from Asian waters, disarm those not withdrawn, and turn over to Japan the whole of Germany’s Chinese territory. A week later, Japan blockaded the German-controlled port of Tsingtao and in early September Japan landed a force in order to assault the port from the rear. By November 7, 1914, Japan had taken the base at Tsingtao. At the same time, Japan also took over Germany’s other Pacific territories and bases, including the Marshall Islands, the Mariana Islands, Palau, and the Caroline Islands, prizes Japan kept as rewards for its participation in the war against Germany. The former German possessions gave Japan’s navy an orientation very different than it had before. Japan’s armed forces were arrayed across the Sea of Japan to China and the continent and, for the first time, had far-flung bases and possessions southward and eastward across the world’s largest ocean.
It is a common view of historians that Japan’s participation in the war was solely to further its territorial ambitions. A typical summary of the period opines that “the Japanese Empire was keen to make the most of the golden opportunity which Germany’s occupation with European events provided. . . . She proceeded to seize every Germany territory in the Pacific she could lay her hands on.” Doubtless this view comes from the Twenty-One Demands that Japan made on China—actually a series of memos that pressed the Chinese to give to Japan the same concessions they had given to Germany, plus several additional ones. The memos put Japan at odds with the United States, which was lamely arguing to restore China’s territorial integrity. In fact, the memoirs of Germany’s Kaiser, written after the war, support this view: “the rapid rise of Tsing-tao as a trading center aroused the envy of the Japanese. . . . Envy prompted England in 1914 to demand that Japan should take Tsing-tao. . . . Japan did this joyfully.”
Yet few history books note Japan’s contributions to the allied effort against Germany. All the great powers, most especially the United States, were apprehensive about Japan’s potential to become the dominant power not only in China but in the Pacific. Germany even briefly tried to pit the anxieties of the North American power against Japan in an effort to save Germany’s Pacific possessions. Britain too was ambivalent about Japan, first demanding that Japan enter the war immediately, then trying to limit the scope of Japan’s operations. But it must be said that Japan adhered to both the letter and spirit of the alliance it had made with Great Britain. In addition to joining the war immediately and taking Germany’s Asian bases, Japan served a number of other roles. First, Japan’s navy helped Britain drive German warships from the Pacific. The Japanese Imperial navy also allowed Britain, and later the United States, to minimize their forces in the Pacific, freeing those ships for duty in waters surrounding Europe. Further, Japan escorted convoys of troops and war materials from the British dominions in the Pacific to Europe—no small task in an era of mine and submarine warfare. Meanwhile, Japanese yards produced both ships of war and merchantmen for British allies. And beginning in 1917, Japan sent two flotillas of destroyers to the Mediterranean Sea to assist Britain in antisubmarine operations and escort troop transports. In the Mediterranean theater alone, the Imperial navy had thirty-two engagements with submarines and escorted a total of 788 allied ships.
One of the few who gave Japan its due was Winston Churchill, who served as Britain’s first lord of the admiralty and wrote a prodigious history of the war. To him Japan was “another island empire situated on the other side of the globe” and “a trustworthy friend.” Similarly, Lord Grey, who served as Britain’s foreign secretary, wrote that “Japan was for us for many, many years a fair, honorable, and loyal Ally.” Nonetheless, when the time came for postwar negotiations, Churchill and Grey were out of office and Britain had obligations to Australia, New Zealand, and the United States, who had all given Britain their firm support in the war.
The Australians and New Zealanders, chips off the Anglo block, were alarmed by Japan’s reach in the Pacific at the war’s end in 1918, and equally aware of Britain’s diminished naval strength. They insisted Japan give up any of the former German holdings south of the equator. Likewise, the United States apprehended Japan, its navy, and its extensive Pacific outposts as a maritime rival and a potential threat to free trade in Asia. As a result, Japan, the United States, Britain, and its oceanic dominions now found themselves in a peculiar geographical and political puzzle.
Japan was Britain’s ally, had built a formidable navy, and had acquired far-flung Pacific bases. Australia and New Zealand were dependable British dominions but strongly preferred to have their security guaranteed by the motherland rather than by Japan. The United States never had a peacetime alliance with Britain, but Britain valued U.S. friendship, and the two democratic, commercial, naval powers sat astride the Atlantic Ocean. Meanwhile, Japanese and American interests and possessions in the Pacific were not separated by any discernible boundary and the two powers viewed each other as rivals. The Americans also insisted on an “Open Door” trading policy in China but Japan clearly had gained the upper hand over the Europeans in that chaotic country.
The Americans had some reason to be concerned about Japan’s new position in the northwest Pacific. Japan had been consolidating its control in southern Manchuria and Korea, had taken over Shantung, and had won most of its twenty-one demands from China. The Open Door policy, the idea that outside powers would compete on equal terms in China and respect its sovereignty, was seriously threatened by Japan’s increasingly advantageous position. Government in China was becoming ever more fragmented and corrupt.
The American government also had domestic pressures to deal with in regard to Asian policy. Navalists saw British power fading and Japanese power expanding. The trend seemed to be toward Japanese dominance in the Pacific. Likewise, American traders wanted the government to take a more aggressive stance that would give them some advantage—or at least, not put them at such a disadvantage in Asia in general and in China in particular. Christian missionaries were also keen to set to work on the vast populations now accessible to their gospel. But worst of all, and most outspoken, the racist Anti-Immigration League in California made barring Japanese immigrants from schools, jobs, and property the sine qua non of their agenda and, consequently, of California politics. The Californians now found allies in various anti-immigration societies in the eastern United States as well as in worker unions and even in recent European immigrants who feared the Asians would not only drive down wages but take their jobs. Thus, the nascent Japanese-American rivalry found expression even at the level of local politics.
Complicating matters further, the Western allies, including Japan, still had troops in Siberia. Their intervention there was a confused, fruitless, and embarrassing attempt to stave the Bolshevik Revolution, or rescue the Czech freedom fighters, or prop up an alternative government, or prevent the massive resources of Siberia from falling into somebody else’s hands, or something similar. Everyone, except perhaps the Japanese, was ready to leave Siberia but not so willing to leave first and allow Japan a free hand. Consequently, the peace conference at the palace Versailles was an infamous mess.
