I received a PhD in Law from the University of Tokyo. My research comprises the political and diplomatic history of
modern Japan. In 2003 I published my first book about the formation of the opposition party in Japan. My second
book, published in 2010, is about Meiji Japan’s restoration of sovereignty through the revision of “unequal treaties”
(now under translation into English). Recently, my interest stretches to several other fields including the history of
political lies and the challenges to them in the form of rhetoric and literature, which results in my third book, "Political
History of Deception: Insincere Politics of Earnest Society", Chuokoronsensho, 2020 March.
