A small faction of Riders have been sailers. Not to mention his armor clashes with his weapon. His armor and attire seem more to be from western countries, but he wields a Wooden Katana. Granted, its very circumstancial evidence, givent he nature of this series, but without a Mount to go off of, he could just as likely be a Horsemaster as much a Ship Explorer. Not to mention that William Adams can be, I believe, called the first "Western Samurai", and one of the few, so he's more than likely one of the most famous out of all who hold that title.
