Overview
Leading the Japanese bridge industry for over 100 years. Representative bridges include Rainbow Bridge and Akashi Kaikyo Bridge.
We will also focus on preserving expressways and Shinkansen viaducts, passing on social capital to the next generation. We also construct high-rise buildings and play a role in the development of social infrastructure.
Construction Results
We would like to introduce the construction results of each project.
Bridge Related Products
We have developed products that take advantage of our technological capabilities as a bridge manufacturer.
We will continue to develop products that meet the needs of social infrastructure development, such as seismic products that protect bridges from earthquakes, aluminum products that are attracting attention as inspection and repair tools, and synthetic deck slabs that are effective in bridge construction and renewal.
