SANWA KAKO

Since its founding on October 1, 1965, Sanwa Kako Co., Ltd. has spent more than half a century evolving with “foaming” technology as a key word for its continued existence—positioning it as a resource-saving technology suited to each era, in pursuit of the efficient use of plastics and rubber.

From our early days, when polyethylene foam and rubber foam were used mainly in household goods, footwear, and civil engineering materials, Japan shifted decisively toward an era of industrialization symbolized by the spread of the Shinkansen, automobiles, air conditioners, and computers. Amid the trend of mass production and mass consumption, customers’ demands for quality grew ever higher. Rather than competing on volume, however, our core strength—the batch-type block foaming method—led us to choose a path that emphasizes “quality” and “fine craftsmanship.”

Later, with the widespread adoption of computers and the internet, along with the advance of globalization, society’s value standards shifted from “mass” to “small lot, high mix.” In the midst of these changes, the “Sanwa spirit” we uphold—small-lot production, high variety, flexibility, speed, kindness, attentiveness, coexistence, mutual growth, proposals, and responsiveness to trends—has become even more closely aligned with our customers’ needs.

As a “pioneer of foaming technology,” we have steadily and sincerely accumulated developments in three areas: new technologies, new products, and new applications. We believe this is the very foundation that has enabled our company to survive and expand its business to the present day. Looking ahead, we will further deepen our commitment to the environment, with “foaming”—a cornerstone of resource conservation—at our core, while combining digital technologies and AI to challenge ourselves in creating even greater value. By extending the experience and know-how cultivated in Japan to overseas markets, we will connect our “Kyo Foam®,” born in Kyoto—a city recognized worldwide—with diverse needs and ideas, and deliver it to customers around the globe.

Please look forward to the future of Sanwa Kako Co., Ltd., as we continue to embrace change without fear and relentlessly pursue innovation.
