Research Areas

Modern Japanese History

1) Political History

I study modern and contemporary Japanese history, covering the period from the Taisho era, which began with the outbreak of World War I in 1914, to 1952, when the Second World War ended and Japan was occupied, achieved peace, and gained independence. In particular, I aim to clarify the characteristics of the era through the interpretation of abundant primary sources held by the National Diet Library's Constitutional Materials Room, the National Archives, and the Imperial Household Archives, focusing on political, diplomatic, and military history.

2) Military and Diplomacy in the 1930s

The Manchurian Incident of 1931 marked the beginning of military, international, and economic competition in East Asia and was a military conflict caused by Japanese military machinations. I explore why the military, which instigated this incident, emerged on the political and diplomatic stage in the 1930s, interpreting this development through changes in international order and social norms.
