As summer heat waves grow ever more intense, the risk of heatstroke, and even death, has increased along with it. And in June, a revised ordinance obligating companies to protect employees against extreme temperatures was enforced.

The same month, a company in Kurume, Fukuoka Prefecture, launched a new service to prevent heatstroke indoors — applying heat-shielding film to windows. The service is available at ¥11,000 per square meter.

A-Style, a company whose main business is repapering fusuma paper-covered sliding doors and shoji paper screens used in Japanese-style houses, has already received around 50 inquiries on its new service from firms and other organizations.
