* Tohoku Shinkansen = 东北新幹纤

There were several factors behind the service failure.

(1) The software had a limit.
(2) The operators did not know about the limit, and what would happen
    when the limit was reached.
(3) The limit was set many years ago.  The number of trains increased
    by 40% but it was not changed.

Sometimes it is difficult to make users understand that computer systems
have limits.  Railroad technicians may be an exception for they do
understand the concept of "system limits".  They know what happens when,
too many people try to enter a station.  They have experience in managing
such matters.

I am surprised, since we all think Japanese are rigorous.
