紀伊水道
Hyōgo has coastlines on two seas: to the north, the Sea of Japan, to the south, the Seto Inland Sea. On Awaji Island, Hyōgo borders the Pacific Ocean coastline in the Kii Channel. The northern portion is sparsely populated, except for the city of Toyooka, and the central highlands are only populated by tiny villages. Most of Hyōgo's population lives on the southern coast, which is part of the Osaka-Kobe-Kyoto metropolitan area. Awaji is an island that separates the Inland Sea and Osaka Bay, lying between Honshu and Shikoku.
