Suicide prevention programs at a national level in developed countries were briefly reviewed, and the community-based suicide prevention programs in Akita Prefecture, in the Tohoku Region of Japan, were also outlined. Suicide prevention programs were proposed in Western countries in the 1980s. A famous example is the national prevention program in Finland that was started in 1986. The national suicide prevention programs in Western countries share some common features such as their comprehensiveness and diversity. Typical policies of suicide prevention programs were categorized according to primary, secondary and tertiary prevention. Regarding community-based suicide prevention programs using a health promotion approach, the Akita prefectural government incorporated a suicide prevention program into the local health promotion strategy "Health Akita 21" in 2001. An outline of the four action programs was as follows: to raise awareness of suicide prevention, to increase opportunities for mental health consultation, to promote both primary and secondary prevention of depression, and to create a supportive environment for mental health promotion. Community-based suicide prevention programs were started in some communities of model projects that are financially supported by Akita Prefectural government. Efforts to evaluate the effectiveness of community-based suicide prevention programs are needed in the future.
