On the Ichinomiya coast located on south Kujukuri Beach, a world famous surfing ground was threatened. A conflict regarding the construction of artificial headlands as a measure against beach erosion took place among the administration of coast, surfers, fishermen and users of the coast in 2010. Roundtable discussions to reach a consensus regarding conservation and use of the coast were held to solve the conflict since June 27, 2010. Meetings were held five times between June 27, 2010 and September 3, 2011, and shore protection measures of the coast and the impact of the construction of the artificial headlands on the beach and surfing grounds were discussed. Finally, a consensus was reached among the administration of coast, surfers and users of the beach. This beach will be the place of surfing Olympic games to be held in 2020.
