国土開発工業 Company Profile

Kokudo Development Industry will challenge itself to transform into a comprehensive construction company with a consistent approach from manufacturing to construction.

Our company was established in June 1973 when the heavy machinery earthworks division separated and became independent from Japan National Land Development Co., Ltd. The heavy machinery earthworks division of the company was the first in Japan to introduce what is now common, such as bulldozers with rippers and swamp-type tracked heavy machinery, during the post-war chaos and the dawn of reconstruction. It also played a pioneering role in the development of underwater bulldozers and has been the only manufacturer of towed scrapers in the country. We have inherited this spirit and have continued our business activities centered on specialized heavy machinery earthworks since our founding. However, as times have changed, so have social needs. We will challenge ourselves to transform into a "comprehensive construction company that integrates manufacturing and construction" capable of undertaking projects beyond heavy machinery earthworks while leveraging the DNA of our traditional heavy machinery earthworks.
