The Northern Osaka Earthquake occurred during the morning rush-hour (7:58 a.m., June 18, 2018). As the results, a huge number of stranded people had emerged in the urban area. A huge earthquake may occur directly beneath the Tokyo Metropolitan area and paralyze the transportation network in the future. The purpose of this study was to evaluate the validity of the evacuation site designation policy promoted by Tokyo Metropolitan government against urban fires that might occur in the event of a major earthquake by estimating the number of evacuees including stranded people and analyzing the effective area per person to refuge at evacuation sites. It was clarified that several evacuation sites didn't have sufficient capacity to ensure more than 1 m2 per person.
