VOC Opperhoofden in Japan were the chief traders of the Dutch East India Company (Vereenigde Oostindische Compagnie or VOC in old-spelling Dutch, literally "United East Indian Company") in Japan during the period of the Tokugawa shogunate, also known as the Edo period.
Opperhoofd is a Dutch word (plural opperhoofden) which literally means 'supreme head[man]'. In its historical usage, the word is a gubernatorial title, comparable to the English chief factor, for the chief executive officer of a Dutch factory in the sense of trading post, as led by a factor, i.e. agent. The Japanese called the Dutch chief factors kapitan (from Portuguese capitão).
The Dutch East India Company was established in 1602 by the States-General of the Netherlands to carry out colonial activities in Asia. The VOC enjoyed unique success in Japan, in part because of the ways in which the character and other qualities of its Opperhoofden were perceived to differ from other competitors.
The first VOC trading outpost in Japan was on the island of Hirado off the coast of Kyūshū. Permission for establishing this permanent facility was granted in 1609 by the first Tokugawa-shōgun Ieyasu; but the right to make use of this convenient location was revoked in 1639.
In 1638, the harsh Sakoku ("closed door" policy) was ordered by the Tokugawa shogunate; and by 1641, the VOC had to transfer all of its mercantile operations to the small man-made island of Dejima in Nagasaki harbor. The island had been built for the Portuguese, but they had been forced to abandon it and all contacts with Japan. Only the Dutch were permitted to remain after all other Westerners had been excluded.
