Edit: also Lincoln would have had to traveled to Paris or Lyon the last year of his life to send a pentelegraph (early fax machine) and said samurai would need to be in the other city to receive it. Not impossible technically, but Lincoln only left the US very briefly at Niagea Falls, never traveled to Europe. So it’s possible, but unlikely.
Did Japan have any fax lines though? Unless you’re talking about a samurai that left Japan
He was visiting the US
