Violation

The former officer of ITO Building Materials Store Inc. was convicted of obstructing fair bidding processes related to a large-scale renovation project for the Kakunodate Furusato Museum (mechanical equipment work), which was publicly tendered by Kakunodate City on May 21, 2019. He received guidance on the minimum bid price from the former mayor of Kakunodate City, facilitated the company's winning of the bid through deception, and thereby impaired the fairness of the public bidding process. He was sentenced to one year in prison (with a three-year suspended sentence) by the Akita District Court on July 25, 2022, and the sentence was finalized. This act falls under Article 28, Paragraph 1, Item 2 of the Construction Business Act. As a result, the company was ordered to cease operations related to public works, specifically those involving construction projects commissioned by national or local government entities or designated public corporations, for a period from October 8, 2022, to February 4, 2023, totaling 120 days.
