A fort located at a strategic location on a sea coast, riverbank, or island. It was furnished with large guns. Daiba were built at the end of the Edo period to defend against possible attacks by foreign ships. The forts built around the bay to defend the port of Nagasaki were the earliest. A well-known example is the Shinagawa Daiba (referred to as Odaiba 御台場), dated 1853, and built to defend Tokyo bay against the black ships of the United States.
