Abstract : An extremely large number of people would experience difficulties in returning home after a large earthquake, since public transportation is expected to be paralyzed and unavailable. In the previous researches, the number of people with difficulty in returning home has been discussed under the assumption that an event would occur on a weekday. In this study, we defined three types of difficulties in returning home, and attempted to compare the number of those people by assuming an event would occur on a weekday and on a holiday. We demonstrated the number of those people on a holiday will be larger than that on a weekday, and showed the disaster mitigation planning for those people on holiday should be considered.

Keywords : ኱ᆅ㟈 (large earthquake)，ᖐᏯᅔ㞴⪅ (people with difficulty in returning home) ， ᖹ᪥࡜ఇ᪥ (weekday and holiday)
