The ministry of land and transportation improved tools for systemic vista management such as vista deliberation by amendment of vista act February 2014. Furthermore, it set up the specific category and process of vista deliberation for development project February 2017 by the amendments twice. The purport indicates that we need to manage huge development projects, which have great influences on national landscape, systematically and have to consider wider category of vista field, which were covered by current urban planning or architectural deliberation. The coverage of vista deliberation for development project are six categories with twenty-eights projects and they should be reviewed by vista committee before the district designation or the formulation of plan. However, there are some problems such as an unclear criteria or an unreasonable procedures on the operating process. The vista deliberation for development is not mandated to local governments and rules development project before the amendment of February 2014 out, as contrary that the principle of vista deliberation for infrastructure or building is so comparatively clear that local government could operate the deliberation based on the principle. Today, vista deliberation for development project are set in as screening projects which are more than 30,000 square-meter in urban area and more than 300,000 square-meter in rural area. Unfortunately these do not work well because the criteria does not fit with reality that the smaller development projects are thriving without reviewing process. The better change is required in order to deal with the development projects as a part of planned urban design.
