Aiko Otsuka

PhD Student, Japanese Studies


I joined Dr Barak Kushner’s project on ‘The Dissolution of the Japanese Empire and the Struggle for Legitimacy in Postwar East Asia’ in October 2013, receiving a four-year studentship. Additionally, I received first Aoi Global Research Award in 2014 to conduct archival work in Tokyo and in London. I have been investigating war narratives of Japanese veterans through an analysis of Japanese official military records, trial documents, and regimental histories.

Subject groups/Research projects

Japanese Studies:

Research Interests

My current thesis examines war narratives of former members of the Imperial Japanese Army (IJA) after WWII. My research focuses on IJA’s infantry regiments that conducted major military operations and instigated various instances of aggression in Asia and the Pacific region in the 1930s and 1940s. I explore the ways in which they recount Japan’s defeat and construct postwar narratives as a way to examine how a defeated army deals with a contentious past.
