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
