The study made a comparison of the draft making process and implementation of open spaces in Japan and China, and pointed out the issues to be solved. In summary, we discovered that the Japanese plan emphasizes joint conduct and cooperation between residents and corporation/organization, while the Chinese plan is characterized by its active usage of administrative lines. Regarding the policies of their plans, there are many similarities in the basic issues for both countries. The study clarified the differences in measures responding to geographical and systematic features of each country.
