Jan Joosten van Lodensteijn (1556?–1623?), a Dutch colleague of Adams' on their ill-fated voyage to Japan in the ship De Liefde, was also given similar privileges by Tokugawa Ieyasu. It appears Joosten became a samurai[citation needed] and was given a residence within Ieyasu's castle at Edo. Today, this area at the east exit of Tokyo Station is known as Yaesu (八重洲). Yaesu is a corruption of the Dutchman's Japanese name, Yayousu (耶楊子). Also in common with Adam's, Joostens was given a Red Seal Ship (朱印船) allowing him to trade between Japan and Indo-China. On a return journey from Batavia Joosten drowned after his ship ran aground.

What permission allowed trade between Japan and Indo-China?
