Violation

Machine-translated summary — verify against original

The former executive director of Enhon Kensetsu Co., Ltd. was arrested on October 11, 2023, on suspicion of obstructing public contract proceedings related to the first phase of the Hirakida Yanahara water intake construction, ordered by the Niigata Regional Development Bureau Rural Development Department. He conspired with a former advisor of Iwamura Corporation and a former officer of Ono Corporation to receive information on the estimated price of the project and used fraudulent means to undermine the fairness of a public bid, leading to his arrest. He was subsequently indicted on November 1, 2023, and on February 14, 2024, he was sentenced to one year in prison (with a three-year suspension of sentence). This conduct falls under Article 28, Paragraph 1, Item 3 of the Construction Business Act.
