■Core Competence

We are continually improving the quality of our flagship Japanese-style roofing tiles and are committed to preserving the beautiful scenery of Japanese roofs. In addition, we develop materials to improve the dehumidification and ventilation of houses: these materials are installed under the roof tiles to improve the performance and life span of housing. The materials help reduce the temperature under the roof in summer and greatly substantially prevent the foundation coating from deteriorating. We are also improving our infrared-based structural diagnostic system, which is used not only for identifying the root cause of a leak in the roof, but also for diagnosing the structure of large buildings such as condominiums.
