What is the capital city of Japan?

Tokyo is the capital city of Japan, which is significant in multiple ways. It is not only the political center of the country but also a major cultural and economic hub. Located on the eastern coast of Honshu, Japan's largest island, Tokyo is known for its unique blend of traditional and modern influences, featuring everything from ancient temples to cutting-edge technology.

Seoul is the capital of South Korea, while Beijing serves as the capital of China, and Bangkok is the capital of Thailand. Each of these cities has its own distinct identity and history, but they are not connected to Japan in the way Tokyo is as its capital. Therefore, in the context of Japan's governance and cultural significance, Tokyo is undeniably the correct answer.
