Why KKJ?
MONOZUKURI Hub

Discover the heartbeat of innovation in the MONOZUKURI hub of KKJ, where tradition inspires tomorrow

 KKJ’s monozukuri (or manufacturing) legacy traces its origins back to the establishment of Yawata Steel Works, a government-owned iron manufacturing plant built in the city’s Yawata district (now, Yahata). This site was chosen for its prime geographical location marked by minimal risks from earthquakes and other natural disasters. KKJ’s proximity to coal from mines in the Chikuho area and availability of iron ore from China also enhanced its appeal as a strategic and ideal location.

Yawata Steel Works

 Industry leaders soon followed suit, with companies such as Sumitomo Metal Mining, Hitachi Metals Industries, Krosaki Harima, TOTO, AGC ASAHI GLASS, Mitsubishi Chemical, YASKAWA Electric Corporation, and Mitsui High-tec putting down roots in KKJ as they spearheaded Japan’s high economic growth. In recent years, a growing cluster of industries in the mechanical and metal processing, automotive, and environmental and energy sectors have emerged, tapping into KKJ’s wealth of expertise in the materials industry.
