While many cases of nails were found in the grounds of elementary and junior high schools in Tokyo, hundreds of nails were also found in the grounds of elementary and junior high schools in Koto Ward and Kita Ward on the 31st.

In Koto Ward, a total of 21 bottles at 772 locations

In Koto Ward, the city's Board of Education visually inspected the grounds of elementary and junior high schools and found a total of 30 nails and metal fragments buried in 21 school grounds by the 772th.

The large nail was about 8 cm long, and the ward board of education removed everything.

The district board of education suspects that the nail that was hammered into the ground during school events such as sports days may have been forgotten, and will carefully inspect the nails in the school yard during the annual facility inspection.

In Tokyo, it was announced on the 31st that as a result of emergency inspections in other wards, nails were found one after another in the school grounds.

In Kita Ward, a total of 7 nails and hooks were found in the playgrounds of seven municipal elementary and junior high schools, and in Edogawa Ward,
a total of 277 nails were found in the playgrounds of three municipal elementary and junior high schools.

The boards of education in each district will now use metal detectors to check if there are any other nails buried in the ground.

In response to an accident at an elementary school in Suginami Ward, Tokyo, in which a student was seriously injured by a nail sticking out of the schoolyard in April, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) has notified boards of education nationwide to ensure safety inspections are carried out at each school.
