Artificial islands for ports/housing
Engineered land shaping city growth
Kobe's Port Island and Rokko Island plans, carried out by the municipal government from the 1960s and 1970s, created large artificial islands in Osaka Bay using earth cut from the Rokko mountains behind the city. The reclaimed islands combined modern container port facilities with planned residential quarters, schools, parks and new transit links, in a strategy the city promoted as moving the mountains to the sea.
The Kobe islands became the internationally known model of municipal land-making, showing a city manufacturing its own ground for port expansion and housing under a single public strategy. They influenced waterfront and reclamation projects across East Asia, while liquefaction damage in the 1995 earthquake sharpened debates about the risks and finances of large-scale reclamation urbanism.
