I want to know the answer to the following question:
What permission allowed trade between Japan and Indo-China?
All the background I'm provided with is that "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.". Is that enough to answer the question?
