(today, May 15) at Yurakucho Station, a Man (in his 20s or 30s) jumped in front of an Ômiya-bound Local Keihin-Tohoku Train and died. Because of this, The Keihin-Tohoku Line, as well as the Yamanote Line (the loop around central Tokyo), the Tokaido Line, (the Shonan-Shinjuku Line, Saikyo Line, and other lines) were stopped or delayed for longer than an hour. An estimated 231,000 people were effected directly, according to JR East.

Now this is something which is a huge issue in Japan, as I've stated before. And this isn't a first time thing at all. If you have me on facebook, you saw that a suicide cancelled a number of trains from Tokyo station which prevented me from getting home sunday. This morning, because of the closure of one train line, other train lines (that aren't even connected physically to those other lines!) were late...and because of that, I ended up sardined against the side of the train I was riding to get to school....and I was late.
Its a huge issue because these people have so many suppressed issues, they choose to let it all out and end it all in a way they could never do before- publicly, dramatically, TRAUMATICALLY (for the driver of that train for sure!) and in a way which will make people always remember who the heck this crazy guy was, because he impacted so many people. I guarantee you that more than a million people were effected by this than the 231,000 stated by JR East.
In Japan, if someone uses an oncoming train to end their life, the train company typically brings their family to court and charges them exorbitant amounts of money. They have the right to as well, because these cause such horrid delays and not to mention the damage caused to this particular EMU.
Japanese people need to learn that if they have depression, or suicidal thoughts, that they need to seek help. I've seen reports and governmental releases encouraging seeking help too, because of how huge of a problem this is becoming recently. As for the victim, I have zero sympathy for someone who does something like this. It causes such a huge mess for everyone involved, and not to mention for the driver who had the horrible circumstance of killing this man.
This is harsh, but its true. I did not need to be late this morning. I woke up as I usually do, I get my breakfast like I always do, and go to school like I always do. Me and everyone else on the trains this morning. We have our own lives, our own issues, and our own problems. This guy's issues, whatever they were, became MY problems this morning, in the form of massive delays and inconveniences. We did not need these. This man should have solved his issues or at least if he wanted to kill himself, do it in a way which didn't cause such a huge mess this morning.
Also there was a second suicide this evening at Tokyo Station which also screwed up some lines. Thankfully it was an isolated line...if it was the same line as this morning, I may not have gotten home tonight.
