Kumagai Gumi faces the most serious management crisis since its founding caused by its large-scale real-estate investments during the economic bubble. The company entered new construction fields, such as mobile communication towers and wind and solar power generation facilities, to proceed with thorough management reforms and survive the construction downturn. The company also began developing new technologies in preparation for the next generation, such as unmanned construction. In 2014, Kumagai Gumi completed the retirement of preferred shares, which are a type of financial support, and thus completed its restructuring thanks to the support of many people.
