Aichi Gov. Hideaki Omura said Wednesday his prefecture will declare a state of emergency on Thursday as infections in Nagoya and its vicinity surged amid an apparent second wave of the virus.

The prefecture-wide state of emergency, to last between Thursday and Aug. 24, calls on residents not to make trips across prefectural borders, while asking them to avoid nonessential and nonurgent outings, according to Omura.

The declaration is aimed at preventing further spread of the deadly virus by reducing people's movements during summer holidays, especially the annual Obon period next week, when many people return to their family homes.
