九宝工業株式会社

Kuhou Kogyo Co., Ltd. was the primary subcontractor responsible for excavation work at a new condominium construction site in Fukuoka City. An employee of the company, who oversees safety management and supervises workers, failed to perform the duties required of a work supervisor under the law, such as deciding on work methods and directly supervising work, on June 15, 2023. This resulted in a fatal accident involving a worker. On June 18, 2025, the Fukuoka Summary Court sentenced the company to a fine of 200,000 yen for violations of the Industrial Safety and Health Act, and the employee to a fine of 500,000 yen for violations of the same law and for professional negligence resulting in death. The case falls under Article 28, Paragraph 1, Item 3 of the Construction Business Act.
