TOKYO, June 2 (Xinhua) -- The Tokyo metropolitan government on Tuesday issued what Governor Yuriko Koike has called a "Tokyo alert" to warn against possible COVID-19 resurgence.
The alert served as a call for caution among the public. If the number of confirmed cases further rises, the Tokyo government plans to issue requests again to businesses and people to halt operation and avoid social activities.
The warning came as the number of new cases began trending higher, with 34 new infections reported in the capital city Tokyo on Tuesday.
The number marked the first time since May 14 when daily infection cases topped 30.
It was also the highest number since the country completely lifted the state of emergency last week.
Out of the newly confirmed cases, infection routes of 12 were unknown, the Tokyo government said.
Tokyo has been the epicenter of the outbreak with the largest number of infections in Japan since late March, and reported its first three-digit increase of 116 on April 4.
Though the number has been gradually declining since mid-April, a slight rise has been shown this week.
