YAZAKI's timeline of success dates back to 1929 when Sadami Yazaki began selling electric wires for automobiles. After important changes in governmental regulations in 1935, Japanese companies were allowed to start domestic automotive production with positive effects for YAZAKI: In 1939 the business could be expanded and in 1941, YAZAKI Electric Wire Industrial Co. Ltd. was established with about 70 employees.At this time, automotive engineering was a promising branch of industry and so in 1949, Sadami Yazaki made an important strategic decision: to focus on the production of automotive wiring harnesses. This was a groundbreaking decision which resulted in today's global leadership.The competencies YAZAKI developed in the automotive business were used to establish various types of equipment for the city gas industry, amongst others, also the world's first solar-powered absorption cooling system, designed and built in 1974. Since then the company has developed and provided a large number of products that support the supply and utilisation of various energy sources, such as electricity transmission cables, gas security systems, air-conditioning equipment and the aforementioned absorption chillers. As a result, YAZAKI began to cater for a safe and environmentally friendly society. These products are now integrated into the environment & energy equipment operations, the second biggest sector in the YAZAKI Group, emphasising its continued commitment to an environmentally friendly future.
