A powerful amenity movement has been raised from the citizens of Hiroshima. So the government decided to launch a landscape improvement scheme along the rivers in the city. And the planmaking and the design were left in charge of us. Based on our survey around the rivers, we set up the design principles as follows: a) conservation of traditional bank images b) encouragement of water front events as possible c) application of local materials d) landscape expression of tidal movement e) assurance of flood control function.
