Sumidagawa Shipbuilding moves to Shiomi

Wikipedia's article on Sumidagawa Shipbuilding records that in 1969 it "moved its head office and works to Shiomi, Kōtō-ku, after its land was bought for the construction of an expressway". After the reclamation was completed, Shiomi grew as a typical semi-industrial district of shipping warehouses, ironworks, shipyards and sanitation depots (Wikipedia).
