The Real Captain John Blackthorn of "Shogun":
http://en.wikipedia.org/wiki/William_Adams_(sailor)
William Adams (September 24, 1564–May 16, 1620), also known in Japanese as Anjin-sama (anjin, "pilot"; sama, a Japanese social title or honorific more or less equivalent to lord) and Miura Anjin (三浦按針: "the pilot of Miura"), was an English navigator who traveled to Japan and is believed to be the first Briton ever to reach that country. He was the inspiration for the character of John Blackthorne in James Clavell's bestselling novel Shogun.
Soon after Adams' arrival in Japan, he became a key advisor to the shogun Tokugawa Ieyasu and built for him Japan's first Western-style ships. Adams was later the key protagonist in the establishment of trading factories by the Netherlands and England. He was also highly involved in Japan's Red Seal Asian trade, chartering and captaining several sailboats to Southeast Asia. He died in Japan at the age of fifty-six, and is recognized to this day as one of the most influential foreigners during Japan's first period of opening to the West.
