TOKYO, JAPAN - FEBRUARY 28: People wearing face masks walk through Shibuya on February 28, 2020 in Tokyo, Japan. A growing number of events and sporting fixtures are being cancelled or postponed around Japan while some businesses are closing or asking their employees or work from home. Prime Minister Abe has also asked schools to close for around a month as Covid-19 cases continue to increase and concerns mount over the possibility that the outbreak will force the postponement or even cancellation of the Tokyo Olympics.
