In 1543, the history of direct contact between Japan and Europe began with the arrival of storm-blown Portuguese merchants on Tanegashima. Six years later the Jesuit missionary Francis Xavier landed in Kagoshima. At first Portuguese traders were based in Hirado, but they moved in search of a better port. In 1570 daimyō Ōmura Sumitada converted to Catholicism (choosing Bartolomeu as his Christian name) and made a deal with the Portuguese to develop Nagasaki; soon the port was open for trade.[citation needed]
