Development in the coastal zone was focused on from functional aspects such as utilization and protection. In recent years, responding to the social demand for nature conservation, numerous projects have been carried out, seeking ways of coexistence with nature. This report presents an outline of the planning, design, construction and monitoring of such an experiment on how breakwaters can be harmonized with nature. Three types of breakwaters were constructed at Maruyama Fishing Port in Hyogo prefecture to compensate for the loss of seaweed beds due to reclamation. In a survey carried out for three years after construction, the situation was judged to have reached mid succession as the number of species and the diversity index of the seaweeds and phytal animals had increased.
