This new scholarly study examines the history of the relations between the British and Japanese monarchies over the past 150 years. Complemented by a significant plate section which includes a number of rarely seen images, as well as a chronology of royal/imperial visits and extensive bibliography, British Royal and Japanese Imperial Relations, 1868-2018, will become a benchmark reference on the subject. The volume is divided into three sections. Part I, by Peter Kornicki, examines the 'royals and imperials' history during the Meiji era; Part II, by Antony Best, examines the first half of the twentieth century; Part III, by Sir Hugh Cortazzi, focuses on the post-war history up to the present day. Published in association with the Japan Society, its appearance marks the abdication of Emperor Akihito and the enthronement of Crown Prince Naruhito in May 2019. It is also a memorial volume to the late Sir Hugh Cortazzi who died in August 2018, shortly after completing his own contribution to the volume.
