In 1542, Portuguese traders arrived in Japan. According to Fernão Mendes Pinto, who claimed to have been present in this first contact, they arrived at Tanegashima, where locals were impressed by firearms that would be immediately made by the Japanese on a large scale. The arrival of the Portuguese in Japan in 1543 initiated the Nanban trade period, with the hosts adopting several technologies and cultural practices, such as the arquebus, European-style cuirasses, European ships, Christianity, decorative art, and language. In 1570, after an agreement between Jesuits and a local "daimyō", the Portuguese were granted a Japanese port where they founded the city of Nagasaki, thus creating a trading center which for many years was Japan's main gateway to the world.
