NIPPO CORPORATION was established in February 1934 with a capital of 1,000,000 yen, succeeding the business of the road departments of Nippon Oil Co., Ltd. (presently ENEOS Corporation) and Asano Bussan Co., Ltd. and inheriting the employees of the road department of Nippon Oil Co., Ltd. and all machinery and equipment of the road departments of both companies. Subsequently, we expanded our business beyond national borders to China, Taiwan, the Korean Peninsula, and other overseas regions. In July 1940, we established Manchuria Pavement Co., Ltd. in Xinjing (present-day Changchun) as a direct subsidiary, and in October 1942, we established branches in Jingcheng, Taipei, and Beijing. However, as the war ended, we lost the aforementioned overseas assets, and we restarted our business in the domestic market.

After the war, we have worked to improve our internal structure by successively opening branch and sub-branch offices throughout Japan and have played a role in road construction projects associated with the reconstruction of the country. Particularly, the first Five-Year Road Improvement Plan, launched in 1954, provided us with an opportunity to enhance our core business of road paving, civil engineering, and product sales by expanding our network of offices, improving our technical capabilities, and strengthening our sales performance. Since around 1985, we have been expanding our business lines and currently, we are engaged in a wide range of businesses, including construction, real estate development, and environmental and PFI projects. Overseas, we have established offices in Guam, China, India, Thailand, Myanmar, Vietnam, Indonesia, and Tanzania.
