Japan has undertaken a large number of land reclamation projects since ancient times because of being surrounded by oceans and having a limited amount of flat land. Recent example includes the Kansai International Airport. Taiheiyo Cement has several limestone mines across Japan, and the limestone produced at these quarries is used not only as a raw material for mineral, but also plays an important role in the steel, chemical, and papermaking industries and is well regarded as a high-quality aggregate in a ready-mixed concrete, concrete products, and civil engineering industries. We are expanding businesses that contribute to society by taking maximum advantage of our abundant resources and expertise.

Receipt of surplus construction soil
We primarily sell limestone aggregate produced at quarries in various regions. Our main products are course aggregate and fine aggregate used in ready-mixed concrete, but sales of aggregate used in concrete products and aggregate used in civil engineering such as roadbed materials are expanding steadily. We also supply sandstone and andesite as aggregate materials. We have established supply bases in each region and ship directly from these mining facilities.
Limestone has multiple functions and is used in a variety of industries. One example is the steel industry. Steel is refined from iron ore, and during this refining process, limestone is used to remove impurities. Another example is the papermaking industry, where limestone is used as an essential paper filling and coating material. We handle a variety of products other than limestone, including quicklime, slaked lime, filler, silica, and silicate pigment. We also use our overseas network to import and sell products that are difficult to obtain in Japan, such as hollow ceramics, sepiolite, wollastonite, and kaolin. Additionally, we export limestone to South Korea and Taiwan and are working to expand beyond Japan to enter limestone markets overseas.
The Mineral Resources Business Company handles all products produced from the earth. Soil and sand extracted from our quarries have been used as reclamation material at Kansai International Airport and Central Japan International Airport. These products will continue to be essential for large reclamation projects. We are also involved in recycling surplus construction soil generated during the construction of large buildings and tunnels. We are able to effectively use soil that was previously disposed of in landfills as a raw material in cement and other products.
