Our company was founded in 1936 as a special dyeing factory. Starting from the dyeing processing industry, we have continuously pursued new technologies with the times, leading to the establishment of our current company, Naigai Special Engineering Co., Ltd., in 1993, based on the idea that "if something doesn't exist, we can create it," after going through the engineering division. We manufacture and sell patented fiber processing machines, various energy-saving devices, and small wind turbines. Among these, we believe that the development of high-performance energy-saving devices that are not bound by existing theories and technologies is necessary. We have been working on management innovation, and in 2010, we received approval from the Governor of Kyoto Prefecture for our management innovation related to the promotion of business activities, and in 2011, we were also certified as a "New Partnership Project" by the Ministry of Economy, Trade and Industry. Our company is constantly striving to respond to the needs of society with new ideas, free from conventional concepts.
