It can be argued that Japan was the least resistant to European influence during the Age of Exploration.
During the Age of Exploration, European explorers and traders began to make contact with various countries and cultures around the world. Japan, unlike China and India, had a relatively small and centralized government, which made it easier for Europeans to establish trade relations. Additionally, Japan was also more open to foreign trade and influence than Korea, which had closed its borders to foreigners for centuries. Japan also had a history of active trade with other East Asian countries, and its merchants and sailors were experienced in trade networks and had a knowledge of European traders. Thus, Japan was less resistant to European influence as compared to other countries during the Age of Exploration.
