During Japan's period of isolation, what was one effect on foreign relations?

• A. Increased trade
• B. Diplomatic engagement
• C. Limited foreign influence
• D. Military alliances

Answer: (C)

During Japan's period of isolation, known as Sakoku, which lasted from the early 17th century until the mid-19th century, the country implemented strict regulations that limited foreign influence significantly. This policy was established during the Tokugawa shogunate and aimed to prevent the spread of Christianity and maintain social order by restricting foreign interactions.

As a result, Japan only allowed limited trade with specific foreign countries, most notably the Dutch, who were allowed to trade at Nagasaki under very controlled conditions. The isolationist policies meant that substantial foreign influence, whether cultural, religious, or political, was effectively curtailed. This self-imposed seclusion preserved Japan’s culture and societal structure but at the same time meant that Japan remained technologically and militarily behind many Western nations until the 1850s when it eventually opened its doors to international trade and relations.

In summary, the correct answer—limited foreign influence—accurately reflects the significant consequence of Japan's isolationist policies during this period.
