D: China.

Explanation:

China, as it is well-known, is one of the oldest civilizations in the world. Although the first Chinese references to the land of what is now Japan date back to “only” the first years of what we call Common Era (marked by the birth of Jesus), it is later recorded that China strongly influenced the language (one of the three Japanese alphabets are made up of Chinese characters), architecture, social forms, and government in Japan. This influence has been marked by historical armed conflicts and an eventual and definitive split between the two nations during the 19th century as the West made its appearance on this region of the world.
