It would seem unlikely that two island nations separated by a vast continent and 13,000 nautical miles of salt water across four different oceans would have a similar outlook and strategic interest. Yet for Britain and Japan, that is precisely the case, to such an extent that Japan was once called the Britain of the East. (Fisher 1968, p. 344) In 1902, Britain ended nearly a century of splendid isolation with an alliance with Japan which formalised a mutual interest that has existed for centuries and upended the strategic map of Asia. Britain provided intelligence to Japan in the Russo-Japanese War and fought side by side as allies in the First World War in the Siege of Tsingtao and the lesser-known Japanese convoy escorts across the Indian Ocean and the Mediterranean with distinction.
