Abstract
Labour accidents in disaster-relief and disaster restoration work following the Great East Japan Earthquake (2011) were researched and analysed in order to raise awareness of the risks and hazards in such work, over a time period from the occurrence of earthquake up to a 18 months afterwards.

In the building work, the predominant type of accident is a "fall to lower level," which increases mainly due to the fact that labourers are working to repair houses and buildings. And in the civil engineering, the predominant type of accidents is a being "caught in or compressed by equipment," due to the fact that working areas are limited in terms of space and subject to over-congestion. congested and limited. In addition, the number of the accidents classed as "fall to lower level" in the building work correlates closely with the number of partially damaged houses in disaster-affected areas.
