Abstract
Decentralization in city planning has been promoted in Japan, and it will continue thereafter. It is important to find the solution in the case the benefit of the municipal government has a conflict with the national or regional benefit. The aim of this paper is to study legal system and roles of national, state and municipal governments of the Netherlands to find the approach of city planning in decentralized society. In Netherlands, discussion among and between different layers of governments is a base for any decisions in city planning. Points of the amendment of Spatial Planning Act and its implementation are studied to clarify how the national, state and municipal governments coordinate in planning in decentralization.
