Violation

A former employee of Keiyo Gas Energy Solution Co., Ltd. was convicted of obstructing public contract proceedings related to the 'Water Pipe Maintenance Work in Ichikawa City, Yawata 2-chome 2-banchi area' conducted by the Ichikawa Waterworks Office of the Chiba Prefectural Enterprise Bureau. The conviction was for using fraudulent means to interfere with the fairness of a public bidding process, resulting in a summary order of a fine of 800,000 yen issued by the Chiba Summary Court on July 3, 2025, which has become final. This conduct is recognized as falling under Article 28, Paragraph 1, Item 2 of the Construction Business Act. Consequently, the Kanto Regional Development Bureau issued a business suspension order for civil engineering work related to public projects in Ibaraki, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa, Yamanashi, and Nagano Prefectures. The suspension period is from August 8, 2026, to October 6, 2026, for a total of 60 days.
