He won the 25th Masayoshi Ohira Memorial Prize in June of 2009 and the Yoshida Shigeru Prize in March of 2009 with his Ph.D.-book of Teikoku Nihon no Shokuminchi Hosei [The Origin and Development of Legal Structure of Japanese Colonial Empire]. After the publication, he has concentrated upon post-war issues of decolonization of Japanese Empire that meant normalization of post-war Japan with divided Asian states in East Asia. As for psychological aspect of decolonization, he concentrated upon strong public and national emotions that had been intertwined with lost human lives of Koreans or Taiwanese and confiscated properties for Japanese, which erupted in the diplomatic process each justified with its laws and memories. Also, he is interested in the theories of nationalism, particularly in the complex of emotion, memory and values (select memories) that would formulate a nation itself. His meta-interests over history lie in how national identity has been institutionalized through civil wars, revolutions, colonial mobilization, decolonization, economic development and democratization. Also, the basic frameworks of recognizing history in the process of domestic and international (two levels’ configurated) politics are some of his additional interests.
