The arrangement that came from the Treaty of Tordesillas eventually led to the accidental arrival of Portuguese settlers in Japan in 1543, when a storm drove their trading ship onto the island of Tanegashima, where they were shortly followed by members of the Jesuits in 1549. A dispute between the Portuguese and Spanish then occurred over the attribution of Japan, and because neither countries were permitted to colonize it, whichever country gained the exclusive right to spread Christianity in Japan meant that they would also have the exclusive right to trade with Japan (Higashibaba, 2001, p. 73). The right to trade with Japan was on the shoulders of the Jesuits, and they now had to form a Christian following in Japan before the Spanish-sponsored Franciscans could, leading to years of effort and dedication to the conversion of Japanese …show more content…

Following Hideyoshi’s death in 1598, Tokugawa Ieyasu succeeded ruling over Japan and became shogun, or military dictator, of the Tokugawa shogunate, and the country was now a unified “one state organization under a single military power” (Higashibaba,
