Tokyo Bay (東京湾, Tōkyō-wan) is a bay located in the southern Kantō region of Japan, and spans the coasts of Tokyo, Kanagawa Prefecture, and Chiba Prefecture. Tokyo Bay is connected to the Pacific Ocean by the Uraga Channel. Its old name was Edo Bay (江戸湾, Edo-wan). The Tokyo Bay region is both the most populous and largest industrialized area in Japan.[1][2][3][4][5]
