Violation

Watanabe Construction Industry Limited's former representative director was arrested and prosecuted for obstructing public contract procedures related to construction and civil engineering projects ordered by Minamiboso City. He was sentenced to one year in prison, with a three-year suspension of execution, by the Chiba District Court on April 12, 2021, under case number Reiwa 2 (Wa) No. 2285. This led to a business suspension order issued by Chiba Prefecture under Article 28, Paragraph 3 of the Construction Business Act, covering general construction and civil engineering work related to public projects, from October 6, 2021, to October 5, 2022. The company’s main office is located at 23 Yama, Minamiboso City, Chiba Prefecture. The legal basis for the suspension is Article 28, Paragraph 3 of the Construction Business Act, applicable due to the criminal conviction of the company's former representative director for obstructing public contract procedures.
