Foreign Office Files for Japan, 1919-1952

Sources from The National Archives, UK

Discover Japan’s rise to modernity and its relations with global superpowers through official British Government documents from The National Archives, UK.

This collection provides significant insight into the events between First World War victory and Second World War defeat, crucial to understanding the political journey of Japan during this period.

Topics covered include ultra-nationalism and the Japanese agenda of imperial dominance in the Far East, employment and social conditions in a time of global economic instability, and the ‘Great Kanto Earthquake’ of 1923 which flattened Tokyo. These documents record relations with Axis Powers in the context of changing alliances, the deterioration of relations with the Allies as World War Two reached the Pacific, and American post-war occupation of Japan.

Sourced from the rich FO 371 and FO 262 series at The National Archives, UK, this resource unites formerly restricted Japan-specific documents and is enhanced by the addition of a selection of FO 371 Far Eastern General sub-series, and Western and American Department papers.
