Business model
In every phase of the construction value chain, the Kumagai Gumi Group demonstrates the comprehensive capabilities of its eight group companies. We are working to diversify our earnings by strengthening our construction business, which is the core of our business management, and adding construction-related peripheral businesses as further growth areas.
Construction contracting business
Domestic Civil Engineering Business

In the area of major infrastructure renewal, demand is expected to increase for bridge deck slab replacement construction along aging expressways. We are focusing on the promotion of construction methods including the Cotter Floor Slab Method for Bridges, which uses joint members to join precast slabs, and the “Kirikata Jozu” method, which separates the slab from the main girder while the road remains in service. In the field of disaster prevention and mitigation, and national land strengthening, we are conducting research and development to improve unmanned construction technologies.
