Japan's education minister says the government plans to announce standards on reopening schools by the end of March.
Koichi Hagiuda spoke to reporters on Tuesday about standards that municipalities across the country can refer to when deciding the timing to resume classes.
Hagiuda said the conditions for reopening schools in a municipality are likely to depend on factors such as whether there are any infections within the municipality or in neighboring ones.
He said that the government will carefully determine whether to completely withdraw its request to close schools.
Hagiuda also said the government will take into account the results of analyses to be released by a panel of experts on Thursday.
He added that ministry officials will be looking at schools that have already reopened to learn what steps should be taken to prevent infections. He indicated that such measures will also be announced.
