JEN , formerly named Japan Emergency NGO , was established in January 1994 as the first federation of Japanese NGOs .
By working and pulling together the expertise of human and financial resources across several NGOs, it has become possible to carry out a project which could not be easier. It also aims for a more collaborative form of humanitarian assistance with the cooperation of Japanese government and organizations.
Since May 1994, 14 offices have been established in different areas in Serbia, Croatia, Bosnia and Herzegovina and Montenegro with international staff delegated to each other. The activity of JEN in the form of Yugoslavia, which has started a half-year project, grew from emergency to rehabilitation over the years. In 2004, all of them were implemented in Yugoslavia and were handed over to local NGOs.
After the 2011 Tōhoku earthquake and tsunami , JEN’s teams of volunteers spread out in Ishinomaki to dig out houses and people from the debris.  They also worked on rebuilding houses.  In 2012 the company UniqloInvested $ 300 million in a group of five NGOs, Including JEN, to Support Their projects. 
In March 2016, JEN received the authorization to operate in Pakistan . 
In October 2017, in collaboration with the Ford Foundation , JEN launched three agricultural projects in Sri Lanka to reboot the local economy after the Civil War . 
At present, JEN works in seven countries including Afghanistan, Pakistan, Sri Lanka, Iraq, Sudan,  Myanmar, and Niigata, Japan and their projects differing from providing rehabilitation of schools in Iraq and Afghanistan from livelihood program in Sri Lanka. JEN worked for the victims of the earthquake in Bagh District, Kashmir, Pakistan
