We found another reference to Mamoru Chikakane. This time he’s listed in an Alien Crew List at the Port of Tacoma near Seattle USA. Reading from a scan of the original record it looks like the ship was the Saikai Maru which sailed from Vladivostock on 15th June 1916 and arrived at Tacoma on 3rd July 1916. Mamoru Chikakane is listed as aged 20, a Coalperson of Japanese nationality, who joined the ship at Kobe on 23rd May 1916.
I travel through Seattle Tacoma from time to time. Strange to think I may have been walking in my grandfather’s footsteps.
