Our society has been destroying the environment for a long time. Environmental destruction has been expanding on a global scale in recent years and exasperating environmental problems, such as the frequent occurrence of extreme weather. The Construction Industry and Environmental Protection These look to be conflicting interests, but that is no longer the case. The activities of today's construction industry make environmental protection a minimum condition. Many technologies are made possible because we are a construction company that has walked together with nature by engaging in environmental protection, environmental restoration, environmental creation, and related activities. We at Kumagai Gumi advocate being "A company that makes the environment No.1."
