I mainly do research on the history of the British Empire and the Commonwealth. I am also interested in inter-imperial relations, particularly those between the British Empire and the Japanese Empire in the late nineteenth and early twentieth centuries. Since I dealt with the transition of British external policy toward its first application to join the European Economic Community (EEC) from the Anglo-American and Commonwealth perspectives in my doctoral thesis (which was submitted to Kyoto University, Japan, in 2006), I am still interested in European Integration as well as Britain’s relations with its Commonwealth partners.
