It is not customary to associate Japan with the Crimean War yet there is a very real connection. When the Russo-Turkish conflict expanded into a general European struggle it made out of the North Pacific and the seas around Japan a new arena of friction. Until March of 1854 the fighting had been confined to the Black Sea and the Near East, but with the entrance of Great Britain and France into the war on the side of Turkey the Asiatic colonies and commercial settlements of Russia were brought within the scope of hostilities. Europe, however, continued to remain the major sphere of battle, which fact tended to eclipse the significance of events that were taking place in and around Japan. Historical treatment of the period of the Crimean War has naturally dealt with these more important phases, ignoring almost entirely the Far East.
