The Tokyo Marathon took place on Sunday against a backdrop of empty streets and with just a couple of hundred runners due to the coronavirus outbreak.
Organisers had reduced the entries to just elite runners and wheelchair athletes with the mass race, which usually attracts around 38,000 runners, cancelled.
The numbers of volunteers were also reduced and spectators were advised to "avoid gathering along the course" and were instead encouraged to "support through TV and radio."
