在日本的外国居民是该国面临灾害风险的弱势群体之一。为了实现日本在重大灾害事件中实现零伤亡的愿景，改进是至关重要的。如果2005年卡特里娜飓风的案例是为了深入了解移民在特大灾害情况下的特点，那么就需要对脆弱性进行更广泛的分析，以避免在预期的特大地震发生时造成大规模伤亡。因此，本研究利用东京都市圈外籍居民的空间分布属性分析其脆弱性。本研究使用多种方法，结合地理信息系统来分析次要和主要数据集。结果显示，外国人在空间上集中在大都市的某些地区，特别是在米纳托市7公里半径内。这些地区的密度使地震社区脆弱性等级分别从1.23%和5.42%变化到2.8%和13.46%。虽然只有11%的外国居民为任何灾难做好了准备，但他们与日本国民之间有着高度的互动感，这几乎消除了社区内的隔离。因此，本研究建议在动员有针对性的疏散程序、疏散中心管理和灾害风险信息传播中利用这些属性。
Foreign residents in Japan are amongst the vulnerable groups at risk to disasters in the country. Improvement is crucial in meeting Japan’s vison of zero casualties in major disaster events. If the case of the 2005 Hurricane Katrina is to offer an insight into migrants’ characteristics in mega-disaster situations, then a broader analysis of vulnerabilities is needed to avoid mass casualties should the anticipated megathrust earthquake occur. Hence, this study analyzes the vulnerabilities of foreign residents by utilizing their spatial distribution attributes in the Tokyo metropolitan area. This study uses multiple approaches that combine geographic information systems to analyze secondary and primary datasets. The results reveal that foreign nationals are spatially clustered in some parts of the metropolis, especially within a 7 km radius of Minato city. The densities in these areas alter the earthquake community vulnerability levels from 1.23% to 2.8% and from 5.42% to 13.46%, respectively. Although only 11% of foreign residents are prepared for any disaster, there is a high sense of interaction amongst them and Japanese nationals, which almost eliminates isolation within communities. This study therefore proposes the utilization of some of these attributes in mobilizing specifically targeted evacuation procedures, management of evacuation centers, and disaster risk information dissemination.
