一般社団法人日本電機工業会

What 一般社団法人日本電機工業会 does

一般社団法人日本電機工業会 (JEMA) is a general incorporated association (non-profit industry association) founded in 1948 that serves as the recognized representative body for Japan's electrical machinery manufacturers, encompassing power infrastructure equipment (generation, transmission, distribution), industrial machinery, and home appliances. JEMA's primary functions are the development and publication of JEM/JEM-TR technical standards, the publication of research reports, pamphlets, and the monthly Denki magazine, the aggregation and dissemination of industry statistics, the organization of seminars and exhibitions, and policy advocacy to the Ministry of Economy, Trade and Industry (METI). It holds delegated authority as a METI-recognized industrial association to develop technical standards and conduct policy research, and is one of the four major electrical/electronics industry associations in Japan alongside JEITA, CIAJ, and JBMIA.

JEMA's core technological assets are the JEM/JEM-TR standards library — specifications covering power systems, power conditioning systems (PCS), programmable logic controllers, motors, transformers, grid interconnection, distributed power systems, and the FL-net industrial networking protocol — and the JEMA-GX Report series tracking the electrical machinery industry's green transformation. The association operates a four-branch national network (Tokyo HQ, Osaka, Nagoya, Fukuoka) and delivers content through its official website, monthly magazine, free pamphlet downloads, paid publication e-commerce store, member-exclusive information pages, and seminars/webinars. The association served as co-organizer of IIFES (Automation and Measurement Advanced Technology Comprehensive Exhibition) and collaborates with government bodies (METI, Ministry of Environment), universities (Aomori Public University), and other industry associations (JEITA, Japan Wind Power Association, JAMP, IPA) on standards, sustainability, and policy initiatives.

JEMA's revenue model is non-commercial: it functions as a membership organization funded by member-company dues, paid publication sales (JEM standards and research reports sold via its online store), seminar and exhibition fees, and limited service fees. The operating footprint is extremely lean — only 8 staff — with substantive technical work delegated to member-company engineers serving on its technical committees. The membership spans Japan's major electrical machinery manufacturers across the full value chain, giving JEMA a unique position to coordinate industry-wide standardization, certification, and policy positions. As of June 2025, leadership transitioned from Fuji Electric's Shiro Kondo to Mitsubishi Electric's Mitsuru Uruma, reflecting the standard rotation of presidency among major member firms.

Direct peers

• ZVEI (Zentralverband Elektrotechnik- und Elektronikindustrie): The German electrical and electronic industry association. Comparable in mission (standards, policy, sustainability advocacy for the electrical industry) and in serving as the central membership body for German manufacturers - essentially JEMA's European counterpart.
• BEAMA: The UK trade association for electrical infrastructure, energy, and building systems. Comparable as a national industry body providing standards input, policy advocacy, and member services for UK electrical manufacturers and infrastructure providers.
• JBMIA (Japan Business Machine and Information System Industries Association): The Japanese industry association for business machinery and information systems, and another member of the same four-association alliance. Comparable in structure, funding model, and standards/policy mandate for its sector.
• JEITA (Japan Electronics and Information Technology Industries Association): The sister Japanese industry association for electronics and IT, part of the same four-association electrical/electronics alliance. Highly comparable in structure: general incorporated association, member-funded, standards and policy advocacy for technology manufacturers in Japan.
• NEMA (National Electrical Manufacturers Association): The U.S. counterpart industry association for electrical equipment manufacturers. Closely comparable in mandate (industry standards, policy advocacy, statistics) for the electrical machinery sector, serving as JEMA's closest international functional equivalent.
• Orgalim: The European federation representing Europe's electrical, electronic, mechanical, and metalworking industries. Comparable industry association at the European level, with similar focus on standards, digitalization, and sustainability policy for the broader electrical machinery industry.
• ANIE (Federazione Nazionale Imprese Elettrotecniche ed Elettroniche): The Italian federation of electrical and electronic companies, part of Confindustria. Comparable as a national industry association providing standards coordination, policy advocacy, and member services for the Italian electrical/electronic equipment sector.
• CIAJ (Communications Industry Association of Japan): A Japanese industry association covering communications equipment and networks, and a member of the same four-association alliance. Comparable as a domestic industry body providing standards, policy coordination, and member services for a related technology manufacturing sector.

Others

• IEC (International Electrotechnical Commission): The international standards body for electrotechnical standards. JEMA engages with IEC and facilitates its members' participation; IEC is complementary rather than competitive, but is the central venue for global standards convergence that ultimately shapes JEMA's role.

Regional players

• KOEMA (Korea Electrical Manufacturers Association): The Korean counterpart electrical manufacturers association. Comparable in mandate (industry standards, statistics, policy advocacy) but operates in a different geography focused on Korea's electrical machinery sector.
