The Nanban trade (南蛮貿易 Nanban bōeki?, "Southern barbarian trade") or the Nanban trade period (南蛮貿易時代 Nanban bōeki jidai?, "Southern barbarian trade period") in the history of Japan extends from the arrival of the first Europeans – Portuguese explorers, missionaries and merchants – to Japan in 1543, to their near-total exclusion from the archipelago in 1614, under the promulgation of the "Sakoku" Seclusion Edicts.
Nanban (南蛮?, "southern barbarian") is a Sino-Japanese word, Chinese Nánmán, originally referring to the peoples of South Asia and Southeast Asia. In Japan, the word took on a new meaning when it came to designate the Portuguese, who first arrived in 1543, and later other Europeans.
Following contact with the Portuguese on Tanegashima in 1542, the Japanese were at first rather wary of the newly arrived foreigners. The culture shock was quite strong, especially due to the fact that Europeans were not able to understand the Japanese writing system nor accustomed to using chopsticks.
