Answer 1
I assume you are trying convey something that occurred in Japan during the 21st century?
If so, I would probably use something like: "In 21st Century Japan .. .. .."
Answer 1
It depends what you are trying to convey. If you are describing Japan and using the timeframe to specify Japan, it would be better to use "Japan of the 21st Century". Example: Unlike Tokugawa Japan, Japan of the 21st Century maintains numerous strong, international relationships.
If you are discussing the 21st Century in general and then move to Japan, it would be better to use "Japan in the 21st Century". Example: America in the 21st Century continue to use their military to solve disputes whereas Japan in the 21st Century is committed to peaceful alternatives.
