Violation

Machine-translated summary — verify against original

NIPPO Co., Ltd. (corporate number 9010001034987) was subject to a nomination suspension from April 11, 2025, to August 10, 2025, by the Kanto Regional Development Bureau, under the provisions of the relevant guidelines for suspension measures related to construction contracts. The suspension was due to violations involving multiple highway construction projects, including those ordered by the Omiya National Highway Office, Tokyo National Highway Office, Yokohama National Highway Office, Nagano National Highway Office, and the Kanto Regional Development Bureau, among others. The violations involved the company’s affiliated plant shipping recycled asphalt as if it were new asphalt, despite contractual specifications requiring the use of new aggregate-based asphalt mixtures. An investigation by the Ministry of Land, Infrastructure, Transport and Tourism revealed that the affiliated plant had used recycled aggregate in the asphalt mixture and had falsely indicated the mixture as new asphalt on shipping documents. The company’s management failed to take appropriate measures to prevent these actions despite being aware of the potential misuse, thus breaching their duty of care. The suspension is part of disciplinary measures for these violations.
