A total of 250 children in elementary school, middle school and high school killed themselves in the fiscal year through March, up from 245 the previous year, according to a ministry survey, Reuters reported.
That was the highest since 1986, when 268 students took their own lives.
“The number of suicides of students have stayed high, and that is an alarming issue which should be tackled,” said a ministry official, Noriaki Kitazaki.
It is difficult to determine the factors behind the increase, he said.
Out of the 250 cases, 33 children were reported to have had concerns about their future, 31 had family problems and 10 were bullied, while 140 were unknown, the survey showed.
High school students in Japan typically graduate at age 18.
Across all age groups, the number of suicides in Japan has fallen to 21,321 in 2017 from a peak of 34,427 in 2003, according to the National Police Agency.
