Our Technology

Create peace of mind.

Technology and quality built on a consistent production system and 150 years of history.

Itagaki's Mikawa Headquarters Factory boasts an area of 52,358m² (1.1 times the size of Tokyo Dome) and has built a consistent production line for steel frame production. The factory premises include a material yard, a mobile painting shed, and a product yard of over 10,000 m². The factory has equipment for primary processing, assembly, welding, and can fabricate columns and beams simultaneously. In addition, we also handle the design and construction of steel frames, and respond to a wide range of customer needs on a one-stop basis. With over 150 years of history since our founding and technology and quality cultivated by the spirit of innovation, we will meet the high demands of our customers.

Providing the world with products that meet strict standards for high-rise and large-scale buildings at H-grade certified factories.

Steel frame manufacturing factories have a certification system that classifies them into five grades (S, H, M, R, J) according to the building scale and the steel materials used. Itagaki Corporation has received "H grade certification" from the Minister of Land, Infrastructure, Transport and Tourism out of this 5-level evaluation. Itagaki provides customers with safe and secure products based on H-grade technology and quality.

It has been more than 150 years since its establishment in the first year of the Meiji era. Challenge to become a company that contributes to the world from Yamagata.

In 1868, the first year of the Meiji era, he founded a blacksmith shop, the predecessor of the current Itagaki. Counting from there, we have carved out a long history of more than 150 years. The origin of our technology is the forging technology of blacksmiths. While firmly rooted in Shonai, Yamagata Prefecture, we entered the Tokyo area early on, and have refined our high quality and advanced processing technology while receiving orders for large-scale projects in Tokyo with a high degree of difficulty, including the Tokyo Sky Tree. We aim to be a company that contributes to the world by continuing to create people's safety and security, accumulating work that will remain in history and on maps.
