A 54-year-old Japanese man was riding motorbike together with a group of friends in Hamamast, Tokyo. He accidentally hit the safety fence at a corner. The cyclist felt painful at his leg but did not realize that his leg fell off from the knee down after hitting the safety fence. He still continued riding until he stopped at the next destination.

A friend of him picked up his fell off leg; it was crushed but still brought to hospital together with the Japanese cyclist.
