Final answer:
The isolationist ideology of Japan initially resisted Western trade encroachment, but eventually adapted by embracing trade and diplomacy to further its national ambitions.
Step-by-step explanation:
The isolationist ideology of Japan initially resisted Western trade encroachment. In the 17th century, Japan adopted a closed country policy, limiting trade and contact with foreign nations. However, in the 19th century, Japan's seclusion began to unravel with the arrival of Matthew Perry and the demand to open up trade.
Despite the resentment towards Western influence, Japanese leaders recognized the value of diplomacy and trade with the United States to further their expansionistic plans in East Asia. Japan later became aggressive in its quest for empire, resulting in conflicts with China and the United States.
Overall, while Japan initially resisted Western trade encroachment due to its isolationist ideology, it later adapted by embracing trade and diplomacy to further its national ambitions.
