Tokyo Dome (東京ドーム, Tōkyō Dōmu) is an indoor stadium in Bunkyo, Tokyo, Japan. It was designed as a baseball stadium following its predecessor, Korakuen Stadium (whose former site is now occupied by the Tokyo Dome Hotel and a plaza for this stadium). In Japan, it is often used as a unit of size; for example, "the new construction is five times the size of Tokyo Dome."
