Abstract

 It is essential to fireproof wooden buildings that could spread fires within blocks of buildings in order to prevent widespread fires and fire whirlwinds caused by an earthquake. Although fireproofing requires joint rebuilding projects that will consolidate lots without road access, conventional large scale redevelopments cannot match (1) the intentions of land owners to create a people-friendly townscape, (2) site conditions that are small, irregular, and specific, and (3) careful financial planning tailored to the needs of various residents including the aged. Our study proves that cooperative methods of rebuilding may effectively function to meet the requirements with professional support and land consolidation under these conditions. A detailed simulation of specific sites in areas densely crowded with wooden buildings in Tokyo indicates that the cooperative method of rebuilding improves the benefits to every stakeholder and ensures project profitability. Further analysis has identified the determinants of project feasibility and confirmed that the method works more effectively for sites with higher land prices and a higher areal ratio of land without road access.
