Series consists of a voluminous amount of communication (approximately 270 letters) between both B.C. Binning and their friends and colleagues in Japan, predominantly Bishop Kojo Sakamoto, his family, and other friends and translators. The bulk of the communication occurs mostly around September 1966 onwards, when Sakamoto’s calligraphy was the focus of an exhibit at the University of British Columbia. Correspondence is presented in the form of letters, traditional scrolls, postcards, telegrams, notes, and a small amount of newspaper clippings.
Series is arranged chronologically by date, regardless of author. There are approximately eighteen correspondences that are undated that were all authored by Bishop and Kiyoko Sakamoto. These follow the dated correspondence.
