By accident, I found your post.
Although I am a student of magic history, I know Sankichi Akimoto (秋本三吉) and Rikimatsu Akimoto (秋本力松) who left Japan in August 1890, together with other troupe members, heading to San Francisco.
They performed in USA until around 1899/1900, and then went to Europe.I don't know how they were related to Masaichi Takahashi.
I am grateful if you could be kind enough to send a photograph of Sankichi Akimoto's tombstone that has a memorial reference to his father Rikimatsu.
