The captain of the San Francisco, Rodrigo de Vivero, was recognized as a former governor of the Philippines, and was granted an audience with the retired shōgun Tokugawa Ieyasu. de Vivero drafted a treaty, signed on 29 November 1609, whereby the Spaniards could establish a factory in eastern Japan, mining specialists would be imported from New Spain, Spanish ships would be allowed to visit Japan in case of necessity, and a Japanese embassy would be sent to the Spanish court.
