The Tohoku-Pacific Ocean Earthquake, which occurred on March 11, 2011, caused serious damage and resulted in numerous fatalities and almost 20,000 missing persons. Furthermore, a major accident accompanied by exudation of radioactive material occurred in the Fukushima Daiichi Nuclear Power Plant.
 A statement regarding the victims' mental health was issued by the Japanese Society of Psychiatry and Neurology on May 21, 2011, which established the Department of Disaster Psychiatry for the provision and assurance of long-term mental care support for the victims.
 The Department of Disaster Psychiatry was consequently reformed in April 2012, focusing on the following objectives: to verify the validity of current mental support methods; to ensure disaster psychiatry and medical care in Japan; and to promote human resource development that can respond to future large-scale disasters.
 Mental health support for disaster victims is of highest priority.
 However, the mental health of relief personnel, who act as front liners during disasters (i. e., police officers, fire fighters, Self-Defense Forces, and health care workers), has often been neglected.
 Therefore, countermeasures for the problems faced by relief personnel are indispensable for a more effective reconstruction. Volunteers are also important members of the disaster relief team and they have witnessed the actual tragedy, and some have experienced burnout. Thus, they require sufficient mental health support, as do relief personnel.
 We thought that the mental health of disaster relief personnel is an important issue; thus, we report their mental health needs, the systematic correspondence to disaster stress, and our works for relief assistance.
 As first responders, relief personnel even without prior disaster education proceed to the area of disaster and may get injured. We therefore suggest that prior to the occurrence of any disaster, networking, education, and disaster awareness should be advocated among relief personnel and volunteers to safeguard their mental health. However, programs on these subjects remain insufficient.
 We extend our utmost respect and appreciation to the disaster relief workforce for doing their best to save lives. We hope that this aids in the reconstruction process of such affected areas.
