The predecessor of Kawaguchi Metal Industry Co., Ltd. was Kawaguchi Steel Co., Ltd., a munitions factory established in 1937. The current Kawaguchi Metal Industry No. 1 Factory was constructed at the time of its establishment and is still operational at the same location. After World War II, the first president of Kawaguchi Metal Industry took over the factory of the dissolved Kawaguchi Steel Co., Ltd., and established Kawaguchi Metal Industry Co., Ltd. as a casting company for the private sector.
From a manufacturing company
to a total solution provider
Kawakin Core-Tech was established in 1948 as Kawaguchi Metal Industry Co., Ltd.
Since then, we have remained at the forefront of casting and bridge product development in Japan.
In 2023, we celebrated our 75th anniversary.
Just as we have transitioned from a manufacturing company to a Total Solution Provider, we will continue to evolve to pursue safety and security for Japan and the world in the next 100 or 200 years.

1958
Commenced the design and manufacture of bridge bearings.
In the lead-up to the 1964 Tokyo Olympics, Japan embarked on a massive social infrastructure development push. Large-scale projects like the Tokaido Shinkansen bullet train line, Tomei Expressway, and Shuto Expressway were launched in rapid succession. As a nation with numerous rivers, bridge construction became a national priority in Japan, driving a surge in demand for bridge components. At that time, cast metal was the standard material for bridge bearings. Recognizing this growing need, Kawaguchi Metal Industry Co., Ltd. began designing and manufacturing steel bridge bearings.

1995
The Great Hanshin Awaji Earthquake occurred.
Up until then, cast iron had predominantly been the material used for bridge bearings. However, everything changed dramatically following the Great Hanshin-Awaji Earthquake on January 17 of the same year. During the earthquake, many cast iron bearings suffered damage beyond what was anticipated, leading to significant effects on bridges. Consequently, seismic isolation capabilities became a necessity for bridge bearings. This earthquake marked a significant turning point for us, prompting the initiation of the development of rubber bearings. Since then, our business development has accelerated in both cast metal and rubber bearings.

2023
Opened Istanbul Branch.
In collaboration with Istanbul Technical University, research began in 2022 to introduce buckling restrained braces ( a type of earthquake-resistant structural element) into the market. During this joint research, the devastating Turkey-Syria earthquake occurred in February of the same year. It is said that the increase in damage was partly due to the lack of proper building standards in Turkey. Following the earthquake, there was a request from local facility and road managers for the early deployment of the buckling restrained braces under development and our seismic isolation, vibration control, and earthquake-resistant devices. In response, we established an Istanbul branch office.
