Japanese local governments that have adopted a "Master Plan for Parks and Open Spaces" are now in the process of revising them. With the amendment of the Urban Green Space Conservation Law in 1994, Japan's Ministry of Land, Infrastructure, Transport and Tourism established a planning system in which local governments draw up master plans for green space conservation and greenery promotion. As of March 2005, 772 municipalities throughout Japan completed the revision of their plans or were revising them. The revisions were necessary after the end of the initial target period for objectives set in the original master plans, and also in response to the growing societal awareness of environmental issues in recent years. Generally, municipalities will be holding public meetings and revising their plans during a two-to-three year period. The following are some of the municipalities working on revisions.

Kodaira City of the Tokyo metropolitan region is seeking comments and suggestions on the draft of the revised green master plan.
Kashiwa City in Chiba Prefecture revised its green master plan in June 2009.
Yokosuka City in Kanagawa Prefecture plans to review the draft of the revised plan and establish a new green master plan in fiscal 2009.
Fukuoka City in Fukuoka Prefecture is inviting public comments on the draft of its new green master plan.
Gifu City in Gifu Prefecture is seeking comments and suggestions on the draft of its new green master plan.
