Last month the Yomiuri News on-line reported the following:
As far as all the 170 stations managed by the Tokyo subway (Tokyo Metro) were concerned, nearly all were ready to manage drinking water and blankets for up to a total of 100,000 people who could be unable to return home from the company at the time of a disaster.
It was done for the purpose of strengthening the preparation to an earthquake beneath the metropolitan area after noting that the stations of the metropolitan area were overflowed with victims who were unable to return home immediately after the occurrence of the East Japan great earthquake. The station space before the ticket gates would be opened up at the time of a disaster so as to admit victims who were unable to return home.
Tokyo Metro was basically having first aid outfits ready at all the stations from now on. The case of the East Japan great earthquake would be used in judging the response that should be taken by stations regarding the opening up of the station space; manual for new stations would be decided upon, and the aim was that all the stations could respond systematically.
Because at the time of a disaster the general telephone could become difficult to connect, for the purpose of co-ordination, a line would be dedicated to unite the timing of resuming operation, so as to avoid confusion caused by passengers overflowing at the connecting stations.
It is nice to note that Tokyo Metro has learned from the 3.11 earthquake and has made preparations for a major disaster that may occur.
