Supplying cement globally and contributing to economic growth in and out of Japan with our Integrated Corporate Strength

Updated April 2017

One of the leading Japanese trading companies in cement market

Cement and concrete are basic materials that are indispensable in the construction of office, residential and other types of buildings as well as for civil and infrastructure engineering works, including bridges and roads. As one of the leading trading companies in terms of cement sales, Sumitomo Corporation supplies these essential construction materials globally, thereby contributing to economic development not only in Japan but in countries around the world.

Sumitomo Corporation's cement business dates back to shortly after World War II, although the business did not grow substantially until 1963 when Sumitomo Cement (currently Sumitomo Osaka Cement) was established. That was the year before Japan first hosted the Olympic Games and the country was in the midst of an unprecedented construction boom amid rapid post-war economic growth. It was in this era that Sumitomo Corporation's cement business truly began to prosper. Since then, it has continued to thrive along with the development of expressways, bridges and other forms of social infrastructure nationwide.

In 1988, Sumitomo Corporation established S.C. Cement, a wholly-owned subsidiary specializing in sales of cement and related products, to expand the company's business in this field. Fifteen years later, the subsidiary started manufacturing ready-mixed concrete in the Kyushu region, marking a significant milestone in the history of S.C. Cement as an arm of a Integrated trading company, given that the company grew to cover a wide range of business processes from upstream to downstream, specifically by adding manufacturing and supply of ready-mixed concrete to its original cement sales business. Since then S.C. Cement has expanded its ready-mixed concrete production capacity, currently operating seven plants in Kyushu and holding the top position in the local market in Fukuoka.

Core supplier in the construction of international airport

Sumitomo Corporation is a dominant supplier of cement and related products in Tokyo and other large city areas, and in particular remains the market leader in terms of sales of ready-mixed concrete in Tokyo and the surrounding urban areas. Behind this unrivaled track record established by Sumitomo Corporation's cement business are strong ties with the company's real estate business. The extensive supplier network developed by the real estate segment throughout the industry serves effectively to allow the company's cement segment to capture information on new construction projects ahead of competitors. This internal cooperation has helped position Sumitomo Corporation favorably to receive orders for a wide range of construction projects, from those involving real-estate properties traded by the company to undertakings for diverse types of urban structures, including office buildings and expressways.

Concrete begins to harden shortly after it is mixed and, in general, site work using ready-mixed concrete must be finished within 90 minutes of production. Large scale construction works consume huge amounts of ready-mixed concrete, particularly during peak times, and it is essential to deliver the required amounts of this "perishable product" according to each user's mix design on time. For some mega projects, temporary plants are often built near work sites to produce ready-mixed concrete, allowing for more efficient supply. Thanks to many years working to meet a broad spectrum of these and other demands, Sumitomo Corporation has gained the trust of users in a wide range of business areas.

Computer control is vitally important to maximize efficiencies in operating ready-mixed concrete plants

Sumitomo Corporation has been the exclusive supplier of cement for a number of mega projects in Japan, including the Tokyo Metropolitan Government Building, Harumi Triton Square and the new terminal of Tokyo (Haneda) International Airport. One of the most recent undertakings involved Central Japan International Airport, nicknamed Centrair, built off the coast of Aichi Prefecture. We set up a ready-mixed concrete plant near the work site jointly with other companies in order to supply the tremendous amount of construction material demanded in the most efficient way. A member of the project team said, "The concrete used in the foundation of the airport structures was nearly 100% supplied by Sumitomo Corporation."

Global player in the cement business

Sumitomo Corporation has also been proactively expanding its cement business overseas. Japan-made cement and related products are globally reputed for their high quality, and the company has steadily increased its exports. Our overseas customer list in this field has extended to include countries half-way around the world, specifically countries in West Africa and South America, in addition to Singapore, Hong Kong and other Southeast Asian countries that are geographically closer.

Recently, we have received in succession cement orders for large-scale projects, including Changi Airport 3rd runway project and Hong Kong International Airport 3rd runway project. By leveraging our Integrated Corporate Strength, we will continue to contribute to infrastructure development in Asia, which will continue to achieve remarkable growth.

Supplier for infrastructure improvement projects that contributes to enhanced safety in society

Sumitomo Corporation's cement business is increasingly demonstrating its strength in Southeast Asia, where we hold extensive trading rights and relationships fostered over years of trading activities in this region. Major economies in this region are moving into a new acceleration phase, aiming to achieve the economic level of developed countries, and increasing investment in infrastructure development. This is expected to dramatically raise demand for cement, which translates into the creation of new opportunities for us to demonstrate our capabilities in this field. At the same time, we will also gear up expansion efforts in emerging markets in South America and Africa, where infrastructure-related demand is strong.

Cement technology has developed at an incredible pace in recent years. Innovative methods and materials used for cement mix have reinvented the centuries-old basic construction material into a new material with super strong properties that can support hundreds-meter high contemporary tower structures. This enhanced strength is expected to play an increasingly important role in modern society, whether that be in Japan or other countries, where concrete structures are spreading, in protecting the safety of people, particularly against earthquakes, tsunami and other such disasters. Bearing the significant function expected of this infrastructure material in mind, Sumitomo Corporation will continue its commitment to developing the cement and concrete business, always looking to contribute to the enhanced safety of society.
