Violation

香南建設株式会社's then-Representative Director, Tatsuya Kitashiro, around December 2020, solicited a local councilor of Kōnan City to obtain the minimum bid price for the demolition work of Sakae Town A Housing Complex, which was scheduled for bidding on the 17th of that month. The councilor obtained an approximate figure of the bid price from city officials and the company won the bid based on this information. Subsequently, Kitashiro provided the councilor with a 100,000 yen gift certificate as a reward. As a result, on September 27, 2022, the Kōchi District Court convicted him of violating Article 96-6, Paragraph 1, and Article 198 of the Penal Code (Law No. 45 of 1907), sentencing him to 1 year and 6 months of imprisonment, with a 3-year suspension. The sentence was finalized on October 12, 2022.
