| Cases of Industrial Accidents Occurred in Japan |
日本の労働災害事例 |
| In Japan, nearly 2,000 workers still die annually in 2000s from industrial accidents and the number of serious accidents in which 3 or more people suffer death/injury tops 200.
In fact, many of these accidents are similar to the past incidents in their nature. Therefore, we need to take full preventive measures against repeating those tragic accidents by case-studying the past incidents.
In light of this, we've decided to describe on this page cases of industrial accidents occurred in Japan including their summaries and leading causes. | 2000年代の日本では年間2000人近くの労働者が労働災害で死亡しており、3人以上が死傷する重篤な事故は年間200件を超えていました。実際、これらの事故の多くは、過去の事故と似たような傾向を持っています。そのため、過去の事故を事例研究することで、悲惨な事故を繰り返さないように万全の予防策を講じる必要があります。そこで、このページでは、日本国内で発生した労働災害の事例を、その概要と主な原因を含めて紹介することにしました。 |
