In 1542 Jesuit missionary Francis Xavier arrived in Goa at the service of King John III of Portugal, in charge of an Apostolic Nunciature. At the same time Francisco Zeimoto, António Mota, and other traders arrived in Japan for the first time. According to Fernão Mendes Pinto, who claimed to be in this journey, they arrived at Tanegashima, where the locals were impressed by European firearms, which would be immediately made by the Japanese on a large scale. In 1557 the Chinese authorities allowed the Portuguese to settle in Macau through an annual payment, creating a warehouse in the triangular trade between China, Japan and Europe. In 1570 the Portuguese bought a Japanese port where they founded the city of Nagasaki, thus creating a trading center that for many years was the port from Japan to the world.
