整備前 [Apartment Complex by the Project]1) Development of
Collaborative Houses and Public Service Facilities
2) Disaster-resilient Urban Development Projects
• Rebuilding• Seismic retrofit• Collaborations
3) Support to Road Development • Selling collaborative houses to the affected persons in advance
•Consultation of rebuilding and relocation
Selling of TMG owned land to private entity selected from the public and develop an apartment complex.
Subdivide the apartment complex to the land owners of the target project area by priority.

Disaster-resilient District Development Program To construct disaster-resilient buildings and
public facilities where aged buildings are removed.
It provides two options regarding change of rights to 1) collaborative buildings and 2) independent lands.

10 Years Project of Fire-resistant of Densely-built Wooden House Areas
Target of the ProjectConcept of the Activities
25
Target of “10 Years Project of Fire-resistant of Densely-built Wooden House Areas”Target of “10 Years Project of Fire-resistant of Densely-built Wooden House Areas”To make Densely-built Wooden Building Areas Resistant to Fire Spread and Inflammation
Especially for the Project Areas (Apx. 7,000ha) where extensive damages are expected are the target of the focused and intensive activities.
To realize “Fire-resistant City” by accelerating fire-resistant projects in urban area. To realize “a City Resistant to Fire Spread” by facilitating formation of Fire Spread Prevention Belt.
Urgency of the earthquake directly underneath Tokyo and occurrence of the Great East Japan Earthquake accelerate the activities to improve densely-built wooden building areas
26
Facilitation to create Fire-resistant City in cooperation with ward governments• To extend the restricted area for fire-resistant• To establish a special assistance framework (Specific
District for Non-flammable) for the district where is required focused and intensive improvement
Concept of the ProjectConcept of the Project
Strengthening of major urban planning road network to formulate a Fire Spread Prevention Belt• To establish a new framework (Specific Road for
Intensive Development) for rehabilitation of the livelihood of land owners alongside the designated roads
Awareness-raising of citizens to formulate a Fire-resistant City• To implement town meetings and individual consultation
