TOKYO (REUTERS) - Tokyo Governor Yuriko Koike warned on Friday (July 31) that the Japanese capital could declare a state of emergency if the coronavirus situation deteriorated further, after new cases jumped by a record single-day high of 463.

"If the situation worsens, Tokyo would have to think about issuing its own state of emergency," Koike said, imploring residents to follow health guidelines to avoid that happening.

Earlier on Friday, Chief Cabinet Secretary Yoshihide Suga said Japan does not need to reimpose a state of emergency, reiterating the government's stance amid a surge in new infections across the country.

Suga said the current trend in infections was different from that in March and April.
