TOKYO: Tokyo said on Friday (Aug 14) it had confirmed 389 new cases of COVID-19, as the daily tally rose above the 300 mark for the first time since Aug 9.
Those under 40 years accounted for 62 per cent of new cases, while serious cases rose by three to 24 out of all current cases in the Japanese capital.
The central government declared a state of emergency in April, but has since resisted reimposing the measures over the potential impact on the economy.
However, Koike has said the capital would have to do so if cases continued to rise.
Local governments in some prefectures, including Okinawa and Aichi, declared states of emergency over the past month after recording a surge in cases.
The country's top doctors have also warned against domestic travel and urged local areas to decide on their own restrictions. They also called for expanded availability of virus testing.
