The reasons the company gives

The company's own explanation, not something inferred from the numbers.

There has been strong demand from metal roofing customers, and the thermal insulation provided by the SOSEI method helps prevent heatstroke and conserve energy. In addition, the shipment area for metal roofing is larger than that for slate roofing, and demand for renovation is expected to increase. The company also aims to provide a labor-saving solution in response to the difficulty of securing skilled workers caused by Japan’s declining birthrate and aging population.
