For those who were already here, I am sure you all have very precise memories of that afternoon (I for my part certainly remember very well those moments and the couple days that followed). One thing is clear, there was a "before" and an "after". For the newcomers, easy advice, don't ignore the safety tips, don't think "it will never happen". For those in Kanto, half a day at the Tokyo Rinkai Disaster Prevention Park makes for a useful and actually enjoyable day trip.
That is all, have a good 3.11
DOUBLE EDIT : can't link to this legendary AC Japan song, it will activate the dreaded autoremove,,,
