Government admits restrictions that had been due to end on 11 May have failed to stop rising infections
Japan is to extend a coronavirus state of emergency in Tokyo and three other areas until at least the end of the month in an attempt to arrest a surge in cases less than 80 days before the start of the Olympics.
The economy minister, Yasutoshi Nishimura, conceded on Friday that targeted measures introduced at the end of last month that were due to end on 11 May had failed to check a dramatic rise in infections.
