Creating a new core business every ten years in line with the corporate mission
 Tostem began business as a retailer, wholesaler and manufacturer of wood interior materials. In 1966, the company entered the aluminum window market. Since then, we have created a new core business roughly every ten years in order to fulfill our corporate mission "Excellent homes and living environments for everyone."
 For the first ten years after entering the aluminum window business as a latecomer, we concentrated on acquiring the top manufacturing position in Japan.
 Our current business foundation was established through aggressive capital investment in superior product development, marketing, production processes and other areas during this period. Shortly after that, we launched balconies as a new product line. Those new products brought us into a whole new market for exterior products. In the following decade, we worked to establish a secure position in the commercial-building window market. Supplying a variety of products to projects ranging from lowrise condominiums to super high-rise office buildings, we built up achievements and technology in commercial-building windows and have supplied curtain wall cladding to over 70% of the skyscrapers now in Japan.
 From the mid-1980s, we expanded our business range into kitchen and bath fixtures, interior furnishing materials and exterior wall materials, such as siding.
 Further, in the 1990s, we launched a prefabricated insulated panel business and, through this business, we are providing not only materials that enhance dwelling performance, but also construction methods that offer a comfortable and healthy home environment all year round.
Adding new value to homes
 Recently, Tostem has been developing products that are not only environment-friendly, but also may incorporate universal design concepts or contribute to greater overall home security, or adapt the home to changes in the homeowner’s life stage. We believe that by promoting such products, we can increase the quality of life as well as the property value of the home itself.
 We are making our best efforts to improve quality and service as we bring further refinement to our operations under the “Total Housing” concept that provides all materials and know-how to build excellent homes.
 On behalf of Tostem, I would like to thank you for your continuing interest and support.
