The recent National average of the rate of suicide in Japan is ranging 16 to 18 point. In this research, fourteen prefectures of which suicide rate were higher, moderate or lower than National average were picked up and every suicidal case in their prefectures (total 31500 cases from 14 prefectures) were investigated in detail, according to the reports from Prefectural Police Head Quarters from 1989 to 1995. By this research, several results were obtained as followings ;
1.Suicidal rate in Akita, Niigata and Iwate Prefectures are always higher, and the actual number of suicidal death in these prefectures is twice or three times higher than that of traffic accident. On the other hand, Ishikawa, Shiga, Mie and Okayama Prefectures show always lower rate than National average.
2.The total number of suicide in male is always higher than that in female in every prefecture and in every year.
3.Both male and female in the aged group (over 65 years old), suicidal rate and actual numbers of suicide are higher than the other group.
4.The background of suicide in the aged group is seemed suffering from the disease, but real reasons for committing suicide may exist on his/her emotional part besides his/her disease.
5.Persons having psychiatric problem in the group under 64 years old, result in occupying the higher portion of committing suicide.
6.Hanging is the most popular procedure for committing suicide in Japanese.
7.Persons who live alone occupy only 10% of portions of committing suicide.
From these results, prophylactic approach for preventing suicide has to be targeted to the aged persons and persons who have background of psychiatric disease.
