Our guide
The Kitan Strait, also called the Tomogashima Channel, separates Awaji Island from Wakayama and links Osaka Bay to the north with the Kii Channel to the south. It is 11 km wide in all, but the Tomogashima islands would shorten the span of a proposed bridge. The strait is part of Setonaikai National Park.
Tomogashima Island is about 3.6 km from the point we map.
