This book offers an account of the life of Shibusawa Eiichi, who may be considered the first ‘internationalist’ in modern Japan, and is written by his great grandson Masahide and published in 1970 under the title Taiheiyo ni kakeru hashi (Building Bridges over the Pacific). Japan had a tortuous relationship with internationalism between 1840, when Shibusawa was born, and 1931, the year the nation invaded Manchuria and when he passed away. The key to understanding Shibusawa’s thoughts against the background of this history, the author shows, lies in the concept of ‘people’s diplomacy,’ namely an approach to international relations through non-governmental connections. Such connections entail more transnational than international relations.
