NARA — It should have been just another day for Takeshi Yamamoto, 56, when he climbed aboard a Kintetsu train at Koriyama Station at 7:38 a.m. on May 10.

Yamamoto (not his real name) was preoccupied with a tennis tournament starting the next day that he was organizing for his colleagues. In his left hand, he was carrying prizes for the meet in a bag as well as a briefcase.

It turned out that Yamamoto, who worked for the Nara branch of a government-affiliated financial institution, couldn't attend the meet.
