Ten Years in Japan is a fascinating and unique look inside the government of Japan before and during the attack on Pearl Harbour. Written from the detailed personal diaries of Joseph C. Grew the American ambassador based in Tokyo from 1932 and up until war was declared in the beginning of 1942. This book deals, as is right and proper, primarily with American-Japanese relations. But for British readers it has a special interest because it covers a period during which British and American policies in the Orient followed parallel lines; a period when the two Governments were grappling with problems always similar and sometimes identical. The interest is not lessened by the peeps that we get of what were, in fact, unremitting efforts on the part of the Japanese to sow discord between Britain and America on the principle of 'divide et impera.'
