How did Tokugawa insolate japan?

Answer 1

The Tokugawa shogunate isolated Japan through a policy known as sakoku, implemented in the 17th century. This policy restricted foreign trade and prohibited Japanese citizens from traveling abroad, allowing only limited contact with designated foreign nations, such as the Dutch and Chinese, through specific ports. The shogunate aimed to maintain political control, prevent the spread of Christianity, and preserve Japanese culture. As a result, Japan remained largely closed off from the rest of the world for over two centuries until the mid-19th century.
