The electric facilities industry with a person and a dream and the purpose of life to value environment


JECA (Japan Electrical Construction Association) was launched in 1948 with the name of Electrical Construction Society. We have been concerned to make the association upgrading and expanding, and electrical construction companies' encouraging initiative, seeking social status. 
We always cooperate with our members all over Japan, and work together with prefectural associations, manufacturers and distributers for various business of electrical construction. We have been involved in the growth and development of electrical constructions industries as national-center more than 60 years.
Now it's a serious problem to supply electrical power stably after the accident of Fukushima nuclear power plant on 3.11 (Great East Japan Earthquake). We maintain the important lifeline which supports economy, industry, and our life in Japan. So we should strengthen safety measures against natural disasters, correspond flexibly to the change of the situation of supplying energy, demands of saving energy. It's also important to provide the knowledge and technology for engineers working on site. 
Through these things above, we are expected to strengthen the saving-energy project and using renewable energy in a positive way to achieve the low-carbon society, which is our medium to long term policy.
We have such a societal demand, we still promote good electric construction business by various measures including the engineering improvement, the business foundation and stable source of manpower. Our mission is to make the electrical construction industry more attractive business with respect people and the environment. It will lead to find motivation in the works for the engineers.
Thank you for your understanding and cooperation.
President, Kiyoshi Goto 


 Security, upbringing of excellent human resources is the pivot of the healthy development of the industry, and I am full of that I call you together for development of the whole electric facilities industry, and, in the electric facilities industry which is labor-intensive industry, the youth whom young worker population carries the future on under the decreasing environment is done with an important problem by the industry.
 I wrestle by an own effort and, in the cause member company of such a background, am carrying out a working experience, the internship of the student for the purpose of improvement of the working awareness of the youth and the contribution to the community in severe management environment.
 Taking into consideration the importance of this approach, I establish the grant system to support the internship that a small and medium size member company carries out as an association, and a burden on internship supports a member of relatively big small and medium size company in the whole industry and aims at the electric facilities industry finding the human resources who, as a whole, are excellent.


The Association aims at promoting the healthy development of electrical construction business and its related business, contributing to the progress of people's security and well-being and public welfare, reconstructing industry, and enhancing culture.
