Over 90 percent of elementary schools have implemented measures to help protect their students from crime, including "hazard maps," according to an education ministry survey.

The survey by the Education, Culture, Sports, Science and Technology Ministry found 90.4 percent of the elementary schools polled had hazard maps — listing areas children should avoid and places to seek help — at the end of March 2005, up from 61.9 percent the previous year.

In addition, 92.7 percent of elementary schools, up from 86.5 percent, have met with parents and police to discuss security issues, up from 86.5 percent the prior year.
