Some areas in Japan are struggling to secure enough public school staff to teach Japanese to children with foreign roots, amid a recent surge in the number of such students in the country, a Kyodo News survey showed Wednesday.

The city of Yokohama, Saitama Prefecture and Fukushima Prefecture began the academic years of 2018 and 2019 without enough Japanese-language teachers, with a deficit of 28 in public elementary and junior high schools, according to the survey of local education boards.

The three authorities were short by 21, five, and two teachers respectively.
