1. China:
* Cultural Influence: China's influence on Japan is profound and long-standing, dating back to the 6th century CE. Japan adopted Chinese writing systems, Buddhism, Confucianism, and many aspects of art, architecture, and philosophy. Even today, Chinese characters remain integral to the Japanese writing system.
* Political and Economic Influence: During the Nara and Heian periods (8th to 12th centuries), China served as a model for Japanese political and economic systems.
2. The United States:
* Modernization and Westernization: After World War II, the US occupied Japan and played a major role in its modernization and reconstruction. This led to the adoption of democratic principles, a market-based economy, and significant cultural influence, including fashion, music, and entertainment.
* Post-War Economic Growth: US investment and technology transfer were crucial in Japan's rapid economic growth after the war.
While China and the United States stand out, other countries have also significantly influenced Japan, including:
* Korea: Influence in areas like art, architecture, and language.
* The Netherlands: Influence in trade and shipbuilding during the Edo period.
* Great Britain: Influence in industrialization and modern technology.
Ultimately, the complex tapestry of Japanese society is woven from threads of influence from various cultures across time, making it difficult to isolate only two countries as having the most significant impact.
