Yamato Kogyo was established in Himeji, Hyogo Prefecture, in 1944. Since then, it has focused on overseas business. Indeed, Yamato Kogyo entered the U.S. market in 1987 as a pioneer among domestic electric furnace manufacturers, and subsequently expanded to Thailand in 1992, and then to South Korea, Bahrain and Saudi Arabia.
Yamato Kogyo has a consistent system that covers production through to sales at its base in each country, and we work on product making to support the social infrastructure of each region.
As a result of the Yamato Kogyo Group’s aggressive overseas expansion, approximately 85% of all group employees are now working at overseas bases.
We have developed each overseas business based on strong relationships with local partners in the respective countries.

From Himeji to the world
Yamato Kogyo Group is a global company with business expanding around the world from its base in Himeji, Japan.
We have established integrated systems from manufacturing to the sale of steel products at each local base, and are working to support the infrastructural needs of the world.
Tirelessly taking on challenges overseas
Yamato Kogyo Group takes pride in having top-class profit performance among Japanese electric furnace manufacturers.
Around 70% of our ordinary income is derived from overseas business, and we believe that the development of the group could not have happened without its overseas expansion.
We entered the U.S. market as a pioneer among domestic electric furnace manufacturers in the 1980s and in Thailand in 1992, with South Korea, Bahrain, and Saudi Arabia following after.
A passion for manufacturing
We believe the biggest reason that Yamato Kogyo Group has become a unique global company in the electric furnace steel industry in Japan is our passion for manufacturing.
Based on our technologies developed in Japan, we have found great partners such as the major U.S. steel company Nucor Corporation and Thailand’s Siam Cement Group. We built up relationships with our partners by dividing the roles so that our partners focus on management matters while we focus on providing technology. Under this type of relationship, we have grown each overseas business.
With our passion for manufacturing, we will continue contributing to the industries of the world as a global company.
