Background : With the elongation of the expected lifespan of Japanese people, deaths of elder people from accidents have started to stand out recently. Purpose: To find effective measures to reduce mortality of elderly people by elucidating age-dependency of mortality from each cause of accidental death. Method : Calculated accidental death mortality rates of age classes from census (Kokusei-chosa) and mortality statistics of 1995, 2000, 2005 and 2010 to obtain age mortality curves. Results : Most accidental death mortalities increased with aging as did others including deaths from life-style related diseases. Most female accidental mortalities are less than male mortalities. Some mortalities of accident are gradually decreasing recently. In particular, the decreases in mortality from traffic accidents during 2000 and 2010 were remarkable. Discussion: Accidental deaths of elderly people are, at least some extent, preventable by improving environmental and social systems. For instance, seat belts and airbags made significant contributions to decreasing mortality from traffic accidents. Elderly people need more attention and care to prevent unexpected accidental death.
