[Via the US Embassy – Tokyo] “Japan is the most seismically active piece of real estate in the world. The Tokyo metropolitan area experiences regular tremors of varying intensities and the probability that a severe and damaging earthquake will occur is high. The consequences of such a quake will vary greatly depending upon the time of day and year that the quake occurs, and no one can predict with any certainty what conditions will be like immediately following an intensive shock.
It is prudent that everyone be prepared to fend for themselves in the immediate aftermath of a big earthquake. Every family and company should develop its own emergency plan and make sure its personnel and their family members are familiar with earthquake emergency procedures and precautions for their safety. Companies and organizations should coordinate carefully with their ward or city office to ensure that they are familiar with Japanese government plans for their area.”
