A 28-year-old man died in Japan after choking on a rice ball at a speed-eating contest, an event organiser said Tuesday. The man, whose name was withheld, died on November 16 in hospital three days after choking, said the local farmer's cooperative that sponsored the event in the western city of Hikone. Contestants competed to see how fast they could eat five "onigiri" balls of locally grown steamed rice, a popular Japanese comfort food. The man shoved his fifth rice ball into his mouth before passing out and was rushed to a local hospital where he later died, the organiser said. Needless to say,he didn't win.
