TOKYO - The daily number of new coronavirus cases reported in Tokyo on Sunday dropped to five, the lowest since the capital was placed under a state of emergency on April 7, and the sources of infection could be traced in all these cases, the metropolitan government said.

In another metropolitan area of Osaka Prefecture, no new case of infection was reported Sunday for the first time since March 9, the prefectural government said.

The two major areas have seen a declining trend in new infections recently, though the central government has come under fire for setting rigid testing guidelines and denying many potential COVID-19 patients access to tests.
