Osaka Bay (大阪湾 Ōsaka-wan Japanese: [oːsakaɰᵝaɴ]) is a bay in western Japan. As an eastern part of the Seto Inland Sea, it is separated from the Pacific Ocean by the Kii Channel and from the neighbor western part of the Inland Sea by the Akashi Strait. Its western shore is formed by Awaji Island, and its northern and eastern shores are part of the Kansai metropolitan area. Major ports on Osaka Bay include Osaka, Kobe, Nishinomiya, Sakai, Amagasaki, and Hannan. Several islands at the south end of Osaka Bay are part of the Seto Inland Sea National Park.
