The Tokyo Metropolitan Government defines the priority improvement areas in the disaster prevention city development promotion plan. The densely-built wooden urban area extends beyond the ward boundary, and it is important for neighboring wards to share issues near the ward boundary and reflect them in their own plans. The following points are examined in this study: how each ward plans the disaster prevention town development plan and ways to solve issues in densely-built wooden urban areas which span multiple wards. It has become clear that there is a contradiction in the policy with the neighboring ward, especially in the road plan, in the current ward's own method of designating non-combustible special zones and the policy of formulating improvement plan, as wards communicate only with Tokyo, not with each other. As a result, there may be inconsistencies in the improvement projects near the ward boundary.
