I think the country I would like to visit most is Japan. Japan is one of the most popular travel destinations in the world. It is a unique blend of traditional and modern with many temples and buildings in architecture and technology.
The current Imperial Palace (皇居, Kōkyo) is located on the former site of Edo Castle, a large park area surrounded by moats and massive stone walls in the center of Tokyo, a short walk from Tokyo Station. It is the residence of Japan's Imperial Family.
