Innovative Research Program on Suicide Countermeasures (IRPSC)



The Innovative Research Program on Suicide Countermeasures (IRPSC) is an extensive research program aiming to promote studies of suicide countermeasures from an international and interdisciplinary perspective. IRPSC is referred to the General Principles of Suicide Prevention Policy (revised), approved by the Japanese Cabinet on July 25, 2017, which is derived from Basic Law on Suicide Countermeasures. Principles state that the Japanese government should proceed with establishing a new guideline of suicide countermeasures and prevention.

IRPSC aims at comprehensively developing an effective research environment for suicide countermeasures. The program also has objectives to establish a framework of evidence based policy-making and practice, well effective for decreasing suicide and exploring its related factors, aiming to achieve goals of Principles.

The program advances the following three focus areas to promote researches for suicide prevention and countermeasures.

I. Research on socioeconomic factors

II. Research for designing governmental policies and its effective implementation

III. Research using public health approaches

IRPSC is operated by its organizing groups which are established based on the IRPSC Research Guidelines. Those groups are consisted of several experts in suicide and its related fields. The Governing Board makes highest decisions relating to the program, Program Directors, appointed to each of three focus areas, review individual studies, and Research Promotion Committee oversees research areas and suggests each studies, as well as an entire program.

Principal Investigator(PI) of each studies advances suicide and its related research taking an advantage of advices from those expert groups. PIs are expected to determine and analyze scientific and policy evidences, effectively to promote a comprehensive suicide policy.


From the Director

Suicide has a diverse and complex cause and background, and it is essential to strengthen interdisciplinary research framework, not limited to health care and psychiatry, but cooperating with various sectors. Moreover, having an international perspective is crucial watching global trends of suicide and progress of its preventive policy. Compared with other OECD nations, suicide death rates of Japan is still high, despite decreasing from a peak of FY 2003.

IRPSC is a newly launched comprehensive research program aiming to reduce number of suicide deaths and its death rates, and "to realize a society in which no one is driven to take their own life." Its objective is also to "lower the risk of suicide in society as a whole by reducing the social factors that are impediments to life (suicide risk factors) and increasing those that enhance it (protective factors against suicide)."

In 2017, the first year of IRPSC, total of twelve external research were conducted. All of them are cutting-edge up-to-date studies having an interdisciplinary and an international standpoint in accordance with a new purpose of suicide countermeasures stated in the Japanese General Principles of Suicide Prevention Policy. IRPSC research outputs are promptly and widely disseminated to advance Japan's suicide countermeasures sharing with global counterparts.

JSSC will vigorously pursue the program to implement its evidence and outcomes to Japan's comprehensive suicide reducing policy. Furthermore, as Director of JSSC, I am confident that research outcomes of IRPSC will be effective for other nations as well.
