The representative director of Sato Construction Co., Ltd. was involved in a bid for a construction project at Yatomi City Hall in May 2025. He used fraudulent means to interfere with the fairness of a public bid, which led to a summary fine order issued by Nagoya Summary Court in March 2026 for obstructing public contract bidding. The penalty was finalized. This conduct falls under Article 28, Paragraph 3 of the Construction Business Act, corresponding to items 2 and 3 of Paragraph 1 of the same article. As a result, Aichi Prefecture issued a one-year suspension of business activities related to public construction projects, effective from July 18, 2026, to July 17, 2027. The suspension applies to construction activities involving public works, including general building construction contracted from clients, as defined by the relevant regulations.
