Final answer:
The geography of Japan and the economic relationship between medieval Japan and Korea played a significant role in shaping their government and political interactions.
Step-by-step explanation:
The geography of Japan plays a significant role in shaping their government. The country's mountainous terrain forced most of the population to live along the coasts, leading to the development of urban centers and a semi-urban society. Additionally, the isolated island location of Japan has contributed to their unique culture and heritage.
The economic relationship between medieval Japan and Korea was characterized by trade and cultural exchange. Both countries had a strong interest in each other's products and resources. For example, Japan imported Korean firearms and books, while Korea imported Japanese copper and silver. This economic relationship played a part in shaping their political and diplomatic interactions during this period.
