The company was founded in 1944 as an electrical contractor for distribution lines and indoor lines, and in 1964 it entered the air-conditioning and plumbing business ahead of its competitors. Since then, in response to the changing times, we have been diversifying our business into growing fields such as environmental facilities, energy efficiency, information and communication, and renovation. In addition, we are developing businesses that are closely linked to local communities and people's lives, such as disaster prevention systems, remote diagnosis support services for medical imaging, wind and solar power generation systems using natural energy, and ecology.
