Ai Koumuten Protects Workers' Lives and Skills with 'Air-Conditioned' Construction Sites: Industry First! Installing AC in All ~3,000 Homes Starting This Summer

Ai Koumuten Co., Ltd. announced that it will install window air conditioners at approximately 3,000 detached housing construction sites nationwide starting in the summer of 2026 (June–September). Amidst rising labor accident risks for skilled workers over 50, the company is taking an industry-first step to provide cooling environments in all homes under construction, in line with the 'Age-Friendly Guidelines' implemented in April 2026. The company aims to reach 10,000 home deliveries and expects this initiative to help secure and retain skilled workers. Recent data from the Ministry of Health, Labour and Welfare shows that accident rates spike for workers in their 50s. The company selected Corona window AC units for their ease of installation without construction work. Furthermore, a system to resell units to recycle shops after use has been established to control costs and reduce environmental impact. Kazuo Tonogaki, Senior Managing Director, stated that investing in worker safety is the top priority, a move welcomed by on-site carpenters.
