Tokyo

Tokyo (東京 Tōkyō), formally Tokyo Metropolis  (東京都 Tōkyō-to) is the capital of Japan, as well as one of the nation's 47 prefectures and the most populous metropolitan area in the world. Naturally, the city and its 23 wards have appeared in numerous kaiju films in some capacity, whether as a primary setting or merely in passing.
