Sarin gas attack on the Tokyo subway, March 20, 1995. ^[1]

It was 11 years ago.
Some of my colleagues have been using the Tokyo subway. I remember that their families worried and phoned the office. Fortunately they were all safe. However, huge number of people was killed and injured.
I don’t use Tokyo subway much, but whenever I walk through the underground, or take a subway, I feel a sort of fear.

I wish that such a sad incident never occur again…
