Tsukudajima (佃島, "Tsukuda Island") is a small island in Tokyo Bay, facing Tsukiji to its west. Originally, Tsukudajima was a tiny island at the mouth of the Edogawa river in Tokyo Bay. It was inhabited by a fishing community who migrated from Osaka in early 1600s.[1] It is home to the famous dish Tsukudani (佃煮).[2] The high-rise district of Tsukishima was built next to Tsukudajima on reclaimed land.
