Under the Newly Revised Seacoast Law, the pilot public involvement project on local beach management and construction of shore protection planning has been executed at Kinoppu beach, in Ohata Town, Aomori Prefecture. Citizens of Ohata have passion to join the project for planning of coasts and rivers in their town. Former ordinary system of planning and construction could not follow the local natural, social andcultural context. But new system to involve the public and local knowledge is still immature. Trials of integration ofthoughts and visions of many sectors show many barriers to be changed. Roles of each joining sector were analyzed.
