Violation

Machine-translated summary — verify against original

上武工業株式会社's former representative was involved in a bid rigging scheme related to the 'Kasukawa District Water Pipe Replacement Project (Project No. 2)' executed by Maebashi City on June 26, 2020. The individual received confidential information about the project's estimated price from the vice mayor of Maebashi City and used this information to submit a near-competitive bid, thereby undermining the fairness of the public bidding process. The individual was convicted by Maebashi District Court on March 15, 2023, sentenced to one year in prison (with a three-year suspension), and the sentence was finalized on March 30, 2023. Based on this, Gunma Prefecture issued a one-year suspension of business operations under the Construction Business Act, Article 28, Paragraph 1, Items 2 and 3, effective from August 3, 2023, to August 2, 2024. The suspension applies to water and sewer construction work related to public projects.
