Corporate Overview

Since its founding in 1935, YODOKO has been supporting people's daily lives and society as a whole through a variety of businesses with steel at their core. From its humble beginnings providing galvanized steel sheets, today YODOKO operates businesses leveraging its flexible thinking and proven technologies across a wide range of fields, from the surface treated steel sheets used as construction materials and home appliance components and metal building products that make up the roofs and walls of buildings, to YODO Monooki storage sheds and other exterior products, steel rolls supporting a range of industries, and even the gratings that keep our cities safe from the ground up. Based on our corporate philosophy to "Make people, communities and the future bloom," we create new value unbound by conventional thinking, and will continue making contributions to the betterment of people's lives and the advancement of society.
