On Thursday, Prime Minister Shinzo Abe asked all elementary, junior high and high schools nationwide to close from Monday through the students’ spring break, which ends in early April.

"Efforts have been made to prevent the spread of infection among children in each region, and these one or two weeks will be an extremely critical period," Abe told a Cabinet meeting, according to Japan Times.

Japan’s health and welfare ministry said Abe’s request does not apply to day care centers for children and after-school facilities for elementary school students.

“The most important thing is to prevent infections,” said Norinobu Sawada, vice principal of Koizumi primary school, “so there aren’t many other options.”
