24 years have passed since the Tokyo Subway Sarin terrorism

 Just 24 years ago, on March 20, 1995, at the very center of Tokyo, the chemical weapon, Sarin was used in the subway terrorism attacks occurred by the Aum Shinrikyo, a cult religion group in Japan.
 13 people died and more than 6000 people were injured.
 On that day in the morning, I was commuting by the Tokyo metropolitan subway to my office, located near the Diet and the Prime Minister's Office. The subway station Kasumigaseki, where the Sarin was spread out is just next to it.
 In the subway, there was an announcement. It said that the subway would not stop at the Kasumigaseki Station. It was strange,, I felt. I asked myself, a poisonous gas, or something?
 Arriving at the office, my family called me to know if I was fine and asked me to watch the TV.
On the TV screen, I saw people suffering and falling down inside and outside of the subway stations.
There were five lines of subway in which Sarin was spread, but when it happened, nobody knew it was Sarin and it took some time to discover it.
 It was also mysterious that almost during one week, we did not know exactly who did such a thing and why. I continued to go to office by subway everyday, but sometimes I felt very frightened to take a subway to go out.
 Today, I would like to pray for victims and their families. Never this kind of terrorism should happen. It is very difficult to understand why the Japanese government permit to exist the successor groups of Aum Shinrikyo.
 24 years passed. The widow of a victim, who was 48 years old is now 72 years old. She could have enjoyed more with her loved husband if it had not happened......
