Hiroshima is famous for the production of oyster, and they have a lot of waste of oyster shells. In this site, all the topography will be made with gabions filled with oyster shells to utilise this waste. Especially, the baby ousters grow on top of other oystershell, Oyster Gabions can be habitat fot them and other marine creatures when
they are put in the places where tide regularly reaches.
