Which country does that strong hotel belong to?

Japanese. The hotel is located in the Japanese Bridge area in the center of Tokyo Station, adjacent to many popular attractions such as the Palace Garden, making it a good choice to visit Tokyo. The area where the hotel is located is the CBD of Tokyo, so you can appreciate the modern temperament of Tokyo more intuitively. The hotel is not only in an excellent location, but also located on the roof, overlooking the whole central area of Tokyo, overlooking the bustling urban landscape of Tokyo in front of the French window. It's really beautiful.
